ShouldeRök™

Is there a user height and bar length correlation? I'm 5ft 8in and wondering if I should buy this one or wait for the shorter one.

Although shorter users may have issues with the device, these can be avoided by holding the Shoulderok higher up the shaft (although this will affect the swing dynamics a bit). For your height (5'8") however, there should be no issue at all. 

How would this work post labrum surgery?

First of all I just want to preface this by saying I am not a doctor and this is not medical advice. That being said, often times when people are having various sholderok issues it's often one of a few things. Either trauma, too much stress/not enough recovery, and or poor movement. Poor movement is something that often leads to added unnecessary stress which in turn becomes harder for the body to repair and will cause a subsequent breakdown over time. This is where the shoulderok can be a useful tool. Using it is not going to repair your torn/damaged tissues, there is already structural damage done. If you're moving in a way that is causing your shoulders to break down extra over time that needs to be stopped/corrected. This is where the usefulness of the shoulderok comes in. It is a tool that will teach you to use your shoulder in conjunction with your core. This is very important because a lot of people are moving their joints off an an unstable base, which the core is suppose to be. Without this proper integration of the core the body, and subsequently the joints, lack stability. When there is a lack of stability, movement breaks down and added stress is placed on the structures. So as I said the shoulderok isn't going to cause your tissues to be repaired, but it can assist in removing the root cause that got you to that point in the first place and hopefully put the body in a scenario that allows it to heal itself more effectively. With all of that said, as I mentioned this is not medical advice nor a promise for the shoulderok to cure your issues. You would want to make sure that doing things like swinging the shoulderok are not going to cause more harm. If you lack the range of motion to get the shoulderok behind your head without compromising position, it is going to hurt not help. If doing things like swinging the shoulderok cause pain, it is likely going to be making it worse not better.

Does the ShouldeRok come with any additional weight to start? How heavy is the actual bar? If it doesn't come with weighting options, how does one go about adding resistance to it when they are ready? Thanks :)

The Shoulderok comes by itself (along with the nut) and weighs 8lbs. You can easily add weight using olympic-sized (regular gym size) plates from 2.5lbs up to 10lbs (25 if you are feeling brave). The ability for users to micro-load the Shoulderok is essential to its function and the user's progression in the swing. If 2.5lb jumps are too big, you can purchase smaller weights online (amazon) or use large washers which have the same diameter inner-hole as a plate. Hope this helps! 

Is there an inherent difference between the zinc, black oxide, and nickel coatings? I am particularly asking about a situation where the ShouldeRok will be in a climate-controlled space. My main point of concern is 'grip' and potential rust.

Hi there, 

All of the coatings are rust resistent.  The strongest finish is the nickel, followed by the zinc, and then the black oxide.  If you are in a particularly wet environment, I would recommend the nickel.  In a climate-controlled space, you can't really go wrong with any of the finishes.

Hello there.... Looking to purchase the black powder coated shoulderok....... Any info on how to or wait time??

Unfortunately, due to some plating issues we've had to stop producing and selling the black oxide Shoulderok. There is something in the works that may interest you, stay tuned! 

What is the shoulderok loadable to? I'm looking to get some heavier maces but may just get this.

This depends on the size of the plates and their thickness. If you use calibrated plates, you can fit much more weight than can possibly be swung (4x 10kg plates can fit easily). We regularly fit up to 50lbs with regular plates, and we've even seen our head coach Chris Duffin swing 45lb plates before! 

How long is the shoulderok?

The full length is 48" or 4 feet exactly. 

Will this help an old weightlifter improve shoulder mobility and stability in the catch position of the snatch?

Absolutely! Our tool is actually used by many archers and shooters for that same reason you mentioned - stability in the shoulder, which for them is important as they seek marksmanship and precision in their sport. 

Do you sell the short version of the shoulder rok?

Yes, the Tactical Shoulderok is a break-down unit that can be used as an Indian Club. See here:
https://store.kabukistrength.net/products/tactical-shoulderok

I live in Portland, can I just pick it up in Clackamas? Or is it being shipped from somewhere else? Also, you mention that there is something "in the works," so is it worth waiting for? Thanks! Stanley

We're more than happy to do local pickups, just shoot us an email with when you want to come by so we can make sure we have one in stock and have one available for you!

is the shoulderok available in the UK? If you ship to the UK how much is the postage ? many thanks in advance cheers Spud

We do ship to the UK. Shipping to the UK for the shoulderok is generally around $70. If you being to go through the checkout process it will give you exact costs to ship to your address

Am awaiting Broomstick you have sent to the UK. Can you ship the shoulderok to the UK as well?

We can indeed!

What are the advantages-disadvantages in regard to the 3 finish types of the Shoulderok? Dia. of plates used to load? Thank you

The different finishes all have slightly different properties that I'll detail out here: 

Zinc - this is the cheapest of the finish options, and will provide excellent corossion resistance, but does dull from a shiny blueish silver color to a gunmetal grey over time (while still being corossion resistant).

Black Oxide - this is our less corossion resistant finish, but still provides plenty of protection assuming the shoulderok isn't being stored in a humid area or coming in contact with water and being left wet. 

Nickel - similar to zinc, the nickel finish provides plenty of corossion resistance but is also harder and more durable. The other advantage to the nickel plating is that it holds its "shine" much longer than the zinc does.

The plates used to load the shoulderok are just standard barbell plates (2 inch hole) 

Which direction is the Nut on the shoulder threaded clockwise or counterclockwise. Mine arrived stuck and I don't want to force it in the wrong direction.

To remove the nut, turn it counter-clockwise (lefty-loosey).  To tighten the nut, turn it clockwise (righty-tighty).  If you have access to one, try using a deadblow hammer to strike the nut in the counter-clockwise direction.  A rubber mallet will work, as well.  Neither of those will harm the nut itself.

Is this made in America?

Yes, it is.  Right here in Clackamas, Oregon.

Does the breakdown version of shoulder roc come in different finishes? If so, how do I select? What are the options? What are the prices? Thanks!

The portable ShouldeRok only comes in black oxide finish.

Can the shoulder roc break down version be purchased in other finishes? If so, which ones and how do I select? What is the price for those? Thanks!

The Portable ShouldeRok is only available in black oxide finish.

How much does it weigh?

The ShouldeRok weighs about 9lb.

I’m a 4’ 11” female. I’m very interested in getting this unit, but am concerned with the length. I’m a little worried this may be too long for me to use for optimum effect. Is there a shorter unit available?

There is not a shorter unit available.  However, our Coach Cassandra is 4'11" and 110lb (when she is not 9+ months pregnant) and she uses the ShouldeRok, if that helps.  That being said, we would not suggest it for an athlete under 4'10".  That is about the limit for comfort.

How much weight can be loaded onto it

That depends on the thickness of the plates you are using.  Deep dish will take up a lot of space, so you will not be able to load as much weight as you would if you used calibrated steel kilo plates.  This piece of equipment is made for increasing the stability and mobility of the shoulder girdle.  If you are looking to load as much as possible, you are not using it for the correct and intended purpose,  The internet may show athletes swinging 45lb and more, but that is absolutely not recommended or the standard.  We recommend starting with a 2.5 or 5lb plate and increasing the weight by 2.5lb increments.

I operate at a CrossFit style gym, do rogue rubber/plastic style (normal Olympic plates) work? Or do I use the smaller 2.5kg/1.25kg plates? In your images it’s steel plates so I’m just unsure - and also, if the smaller 2.5/1.25kg plates do fit, how many can I use (or is a few 2-4) going to be tonnes of weight for it? Hope this all makes sense

Bumpers, iron pound or kilo change plates will all work with the ShouldeRok, as long as they are Olympic-sized change plates.  We suggest starting with a 2.5lb plate and moving up by 2.5lb increments from there, as you learn to use the Rok and your body gets used to the motion.  All ShouldeRoks come with a training video for the user to learn how to use it correctly.

Are there shoulderoks available to purchase at the kabuki gym? I live in Portland and would like to avoid shipping costs if possible. Thanks

You are welcome to make your purchase through our online store and select, 'Local Pick Up', as your shipping option.  Then, when the equipment is ready, our Shipping Team will reach out via email to set an appointment for you to pick it up at our manufacturing facility.  If you do not see that shipping option at check-out, feel free to reach out to our Customer Service email at; info@kabukistrength.com and we can create a draft invoice for you with the shipping removed.

For the "Breakdown" version, is there any "tail" attachment if you use the half as an "Indian" club? thanks!

For the Portable ShouldeRok, the tail is permanently affixed to the end of the Rok.  There is no way to attach it to the 'top' end of the Rok.

I have osteoarthritis in my shoulders. The left one is bone on bone but I continue to train my shoulder as much as I can. High rep/lighter weight. I have been using indian clubs for years that help a lot. Do you think I can benefit from using the Shoulderok??

Many people with pre-existing shoulder issues have benefitted from the increased mobility and stability training effects of the ShouldeRok.  We would suggest viewing the training videos that come with the Rok, starting with very light weight and moving up slowly by 2.5lb increments.

Hello I purchased my Shoulderrok 09/04/2021. Always have had stiff popping shoulders. After few days of swinging popping is gone, and not as stiff. I have had a AC joint sprain about 12 months still have pain in that right shoulder. I know my wrist are sore from jumping up in weight to fast/getting use to proper form. But the shoulder with ac joint is a little sore. Just would like some input. Love the product, and can’t wait to get home and swing.

Cedric; Thank you so much for your feedback.  We are very glad to hear you are experiencing improvement with your shoulder issues by using the ShouldeRok.  As with any new exercise, there will be an adjustment period while your muscles adapt to the new movement.  This can result in slight discomfort after training.  This is why we stress that athletes start with light to no weight when using the ShouldeRok, in the supplied training videos.  This will give your muscles, ligaments and tendons time to gets used to the motion.  We would suggest dropping the weight to 2.5-5lbs for a few weeks and when you stop feeling discomfort, move up slowly by 2.5lb increments after that.

Hi, Do you ship to the United Kingdom? If not, is there somewhere / someone in the UK I can buy Kabuki products? Thanks! --Sanatan

Unfortunately, we do not have an EU distributor for our products.  However, we absolutely ship anywhere UPS goes in the world.  Just enter your shipping address at check out and all applicable shipping options will autopopulate.

does this product come with free instructional videos? or are those add on prices? generally, can we learn from any mace video insrtuctions (from non kabuki people) and use the kabuki with it? the same exercises can generally be used with the shoulder rok and a standard mace?

The ShouldeRok does come with in-depth instructional videos.

My nut and bolt is stuck and I am having a tough time removing it. Is there a way I can solve this issue?

We suggest attempting to remove the nut by knocking it in the correct direction with a rubber mallet or a dead blow hammer.  This will apply force without damaging the nut itself.  I have heard of people using a smaller change plate to do the trick, but this may damage and leave dents in your nut and the plating.

Did you guys add a new logo to the shouldeRok? I notice a picture on Instagram and was curious. It has two ShouldeRok crossing, Also do the weights you guys offer fit the ShoukdeRok?

The current version of the ShouldeRok does not have the design at the end of the Rok.  All Olympic-sized change plates will fit on the ShouldeRok, so the iron plates we manufacture will fit.

What finish is the portable shoulderrok?

The portable ShouldeRok is the black oxide finish.

Hi guys, I'm preparing to buy the Shoulderok and have a few questions. I live on a small island in the Philippines and it's very humid and can be salty. I bought a Cerakote bar from Rogue and in less than 2 yrs it was completely rusted all over so bad that I had to strip the cerakote off. I accept that I will have rust issues, but would like the best option to avoid that if possible. So open to advice. Next, what's the weight of the foldable version in the box for shipping vs the single pc? Does it still come in the carry case like in Coop's review? I will be sending it to a shipping forwarder in the US, so need to know the exact weight in advance to calculate the shipping. The cary case seems like a good advantage. Also does the foldable version have the new mobility tool part on the tail? Many thanks

For any humid environment, we would recommend our nickel finish.  It is the most corrosion-resistant plating option we offer.  You will want to treat it (and all of your barbells) with a light coat of 3in1 or mineral oil, applied with a cloth a number of times a year.  That will assist with corrosion resistance.  

In regard to the Portable ShouldeRok, it does not come with a case.  Our Tactical ShouldeRok was the product that came with a case, but we had to remove that as an option over a year ago when COVID made case acquisition difficult and we had multiple quality issues with the cases that were delivered.  The price of the product was decreased and it was rebranded as the Portable ShouldeRok.  It does not come with a case or a 2.5lb weight now, but it does have the IASTM friendly end piece. 

The Portable ShouldeRok weighs the same as the regular ShouldeRok at 9.4lb.  When it is packaged, it weighs about 10lb.

Will this be an effective too to retrain scapular movement? I have dealt with scapular clicking and grinding against the rib cage especially when raising the arm into an overhead position.

We can’t guarantee that it would fix your specific medical issue and this isn’t medical advice, but people have used the ShouldeRok to retrain scapular movement with success in the past.

I am torn between the Nickel vs the Zinc. The zinc is rust resistant for the most part? I work out in my garage in the hot and humid Louisiana weather.

Yes, there is very little difference between the zinc and nickel plating.  If you can store your equipment in a climate-controlled area and then use it in the garage, that would be best.  You can also treat it once a month with a light coat of mineral or 3in1 oil, applied with a cloth.  That will help keep corrosion at bay.

I've been dealing with multiple rotator cuff issues in my right shoulder, both front side and back side. After my first injury (front side), my shoulder has been incredibly stiff, barely being able to get into position for low bar squats and i can bare get my right arm on my back. Could the Shoulderrök help me regain my mobility and maybe even prevent future injury to my rotator cuff? Thanks you in advance.

Do y'all do will call pick ups in Portland?

Yes, if you are local to the Portland area and would like to pick up at our Clackamas manufacturing facility, that is an option with most products.  Please reach out to our Customer Service Team at; info@kabukistrength.com with your name, billing address, telephone number and list of items you'd like to order with the information you'd like local pick-up.  They will create a draft invoice for the items with the shipping removed and correct notes for our Shipping Department.  Once you've paid for your order and the items are ready, our Shipping Manager will reach out to set up an appointment for you to collect your products.

I’m 6’ talk, my basement gym has 10’ ceilings. Should I be able to use the shoulderok in my basement? In other words will there be sufficient clearance?

Unfortunately, no.  The ShouldeRok is 4 feet long and you will be gripping it at the base and swinging it over your head.  A 12 foot ceiling would be safe, but a 10 foot ceiling will be too short.

What is the weight of each of the two halves of the tactical/portable breakdown version?

Could the shoulderok help address shoulder blade issues such as a winging shoulder blade?

The ShouldeRok won’t always address the underlying cause of this particular issue, but it can be a great maintenance tool for facilitating other changes you might need to make to help solve that issue.

I plan on buying the shoulderok but wanted to ask if the break down version is made with the black oxide or another finished type and also how durable is the break down version compared to the bright nickel finish.

Yes, the portable ShouldeRok is the black oxide finish, which provides little to no corrosion-resistance.  If you are concerned about corrosion, I would highly recommend the nickel plating option.

I have a new Shoulder Rok and the nut has somehow become completely stuck to the top of device. It won't rotate at all. I didn't did anything weird to it, like bang it or something. It was just sitting in my workout room and when i went to use it it was stuck. I tried WD-40 to no avail. Is this a typical problem? Is there a recommended fix? I have been loving it otherwise!

Sometimes the threads of the ShouldeRok get damaged over time during the loading of weight, if the plate is not supported by hand all the way down the shaft. I have also had experiences when someone would load a Rok and overtighten the nut.  It only needs to be finger tight.  When our ShouldeRok nuts get stuck in The Lab, we use a dead blow hammer or rubber mallet to knock them loose.  That way it won't dent the nut.  I have heard of people using a 5lb plate to knock them loose, but I wouldn't recommend that if you have access to a dead blow hammer or rubber mallet.

Does the Shoulderok come with any weights? Does your company offer Military Discounts?

Unfortunately, the ShouldeRok does not come with any weights.  

What is the maximum number of plates that can be added? I want to avoid very wide plates (e.g., 25 lb) and want to know how heavy I can make it without using wide diameter plates.

Hey Saman,

This is going to depend on the with of your plates, but when subtracting the width of the nut to hold the plate on, there is 2.375" of loadable space.

I have had a Shoulderok for over a year now and use it 2-5 times/week. I have been using it with a 5 pound plate on it the whole time. I am wondering how to scale the weight and when to add more? I feel like I am not getting as many benefits as I was originally when I started with the 5 pounds. Thank you!

Hey Torin,

We recommend adding load in 2.5 lb increments as you're able to adapt to it. Another fun thing you can try is working on single arm swings with less load. 

For the ShouldeRök, are there any benefits to the different finishes (clear zinc, black oxide, bright nickel)? Or are they purely for aesthetics?

The different finishes/plating options offer different levels of corrosion-resistance and protection.  The nickel finish is the most corrosion-resistant finish that we offer.  The zinc finish is the next level of corrosion-resistance and black oxide offers very little protection.  Therefore, if you live in a humid area, the nickel finish would be your best option.

I am 6'2", my ceiling height is about 9'6", do you think I will have issue with the Rok smacking into the ceiling?

Yes.  For safety, you will want a minimum of 5 feet of overhead clearance for the ShouldeRok - just in case.

"The length of the ShouldeRök™ is designed to maximize balance as well as the eccentric opening and the requirements for muscle engagement and stability." Please explain what this means.

This is meant to explain that the length of the ShouldeRok creates a long enough lever that it makes the swing smooth, but the lever being longer also makes the swing more challenging and creates higher demands on the muscles involved.

Hi does shoulderok ship to Taiwan?

Yes, the ShouldeRok does ship to Taiwan.  Just enter your shipping address at check-out and all available shipping options will populate, so that you can select the best one for your needs.  Most of our international customers prefer UPS's Worldwide Expedited Shipping option, since it covers customs brokerage fees in most countries and has a pretty timely arrival.  Thank you.

How high of ceilings are required?

It depends on how tall you are.  I am fine swinging the ShouldeRok in a room with a 10 foot ceiling (at 5'4), but my 6'7 friend would be cutting it a bit close.

Been greatly enjoying my black oxide ShoulderRök since 2017. I've noticed some very slight rusting, which is unusual as it's always indoors and away from moisture. Encountered an issue today with the nut freezing in place on top a 5-lb plate, won't budge. Before I take a monkey wrench to it and grease up the threads to avoid this issue in the future, do you have any tips or tricks for care and maintenance? Thanks.

Rubbing the surface of your ShouldeRok down with mineral oil a couple of times per year will help prevent rust damage.  If it starts to build up, just use a wire brush lightly over the surface until you no longer see the discoloration.  In terms of having the nut freeze on the threads, utilizing a dead blow hammer or rubber mallet will usually knock it loose with little to no damage.  Thread damage usually happens when someone in the gym is loading weight onto the ShouldeRok by dropping it down the shaft, rather than carefully supporting it by hand to the base.  Even when small weights are dropped into place, it damages the threads over time to the point the nut will no longer thread on, or off correctly.  Once the threads are compromised, there is not much anyone can do to fix the ShouldeRok, so be vigilant about teaching people how to load the ShouldeRok with care.

Am I going to have a hard time with the Shoulderok being that I’m 5’6?

At 5'6 you won't have a hard time with the ShouldeRok, I promise.  I'm 5'4 and swing it comfortably.

I have severe scapular dyskinesia in my right shoulder and I'm curious if the Shoulderok could cure it? I find it near impossible to properly activate my serratus anterior and go through the correct mechanics when performing the corrective exercise such as weightless flat-on-ya'-back military presses. *It's worth noting that there's no pathology of thoracic nerve damage. Thank you, Kabuki!

We cannot promise you any results.  However, we have yet to see a shoulder issue where the ShouldeRok hasn't at least provided some benefit.  Please read the reviews on our product, where you will see customers commenting on the positive results they've experienced with a multitude of shoulder issues using the ShouldeRok.

How do you add the weight?

In order to add weight, you would remove the ShouldeRok nut, add 2.5lbs, 5lbs or whatever weight you prefer, then replace the nut.

Hi, I have a history with shoulder dislocations and am looking for a way to strengthen my shoulders. Of course the Shoulderok looks great for this purpose, but I am a bit worried of it actually causing dislocation, since it work through the unstable position of my shoulder. Do you have any experiences using the Shouderok for rehab of these kinds of issues? Best, Arjan

Hello, if that position is one that causes issues with the disolcation of your shoulder, I would highly recommend checking with a PT or other physician before using the shoulderok. If you do end up trying the shoulderok as a solution, my advice is to just start slow in terms of weight and progress it at a reasonable rate starting with some of the more remedial swings that are detailed in the instructional videos that are included. 

Hi, I recently purchased and received a ShouldeRök and am still learning how to use it - but loving it so far! I have a question RE: programming and progression. If I start with an empty bar 3x/week, how much and how often should I increase weight? I'm not very strong, but I've got some Olympic-size change plates (down to 1.25#) so I can do some micro-loading. Thanks!

A lot of this is going to be based on individual response, but increasing the loading by that 1.25 lbs every 1-2 weeks would be a good starting point. I would just let your technique be the limiter and continue to progress as you're able to without deviations in technique. You'll get to a point of diminishing returns eventually as there's likely not a point to increasing by that forever and trying to do 45 lb shoulderok swings. More is not always better and generally about 20-30 lbs is as heavy as anyone around here ever needs to go. 

How much weight can you add to the ShouldeRok?

The shoulderok fits all standard sized plates and has 2.5" of loadable space, so it will depend on the thickness of your plates. 

Dear Sirs, I plan on buying a shoulderok I don't understand about adding weight were do I buy the weight or can I use my own weights and how do you put the weight on. Thanks Tim Rudd

The Shoulderok fits standard olpymic sized plates (2.5/5/10/25/35/45)

I have past neck issues (disc bulge) and tightness in the scalenes/scm muscles as well as a TMJ dysfunction but it's getting better since I started strengthening my neck muscles. Would the ShouldeRök be something I can use or isnt it recommend for tight necks? Thanks Michaela

First of all I just want to preface this by saying I am not a doctor and this is not medical advice. That being said, often times when people are having various sholderok issues it's often one of a few things. Either trauma, too much stress/not enough recovery, and or poor movement. Poor movement is something that often leads to added unnecessary stress which in turn becomes harder for the body to repair and will cause a subsequent breakdown over time. This is where the shoulderok can be a useful tool. Using it is not going to repair your torn/damaged tissues, there is already structural damage done. If you're moving in a way that is causing your shoulders to break down extra over time that needs to be stopped/corrected. This is where the usefulness of the shoulderok comes in. It is a tool that will teach you to use your shoulder in conjunction with your core.

When there is a lack of stability, movement breaks down and added stress is placed on the structures. So as I said the shoulderok isn't going to cause your tissues to be repaired, but it can assist in removing the root cause that got you to that point in the first place and hopefully put the body in a scenario that allows it to heal itself more effectively.

Hi kabuki strenght I have gone through a herniated disc operation for 6months ago. Now I wonder if it is safe for me to use the shoulderrök.

I would consult your healthcare provider as recovery times for that sort of operation are highly individual. If you're able to do the movement without pain and compensation then it is likely that you would be fine to start, but again please talk to your healthcare provider first.

The nut that tightens the weight down on the shoulder rock will it loosen after a 100 rep set

That is a new question/issue that we have not encountered yet, but you can place a locking collar on top of the nut for added security

What is the overall length?

The total length is 48 inches

How much does the bar alone weigh ?

The Shoulderok unloaded is 9lbs.

I plan on buying a boomstick maybe this week but I also intend on getting the shoulderok as well soon. My question is do many women use this? And can it help my wife with post surgery rehab of a rotator cuff surgery? I heard in a video that you have some physical therapists using this now. If so can you give me a name of a therapist so I can have my wifes therapist call if they are resistant for some reason to using this?

I should have read your Q &A info. My questions were answered. However, I am concerned in regard to the question about the corrosion on the nickel plated Shoulderok. Is this a problem ? Thank you. Joe

Hey Joe,

I skimmed through the questions but didn't see anything about the nickel plating having issues, but it's possible that I may have missed it. That is our highest quality and most durable finish that we use and should provide plenty of corrosion resistance for years and years to come, and we warranty that, so if there are issues we will replace it free of charge.
