Thank you for the review! We've already addressed the magnetic pin issue. The new pins have zero chance to of the magnets falling out. The bracket was also designed to fit true 3"x3 uprights since our GR3 power racks now use true 3"x3" uprights. There is a second set of holes on the bracket to allow it to fit more snug on metric uprights.
@@griffin_fitnessthanks! Could you also please give us an idea on the weight of these with the handles attached? They appear to be super heavy from coops comments.
I was looking at those but couldn't find much info or reviews on them. I ended up ordering the Bells of Steel Hydra arms. They lock in position but could also use more holes because the lock positions are limited. I just got the Kaizen adapters for them Monday and have the Gym-Pin Taco handles on the way. Overall I love trolley lockable jammer arms. Seated overhead press with them is now my favorite shoulder exercise. No kicking up dumbbells anymore. With the Kaizen adapters I can start wide and end with my hands together...... absolutely love them. They're also great for shrugs and presses when using the spotter arm mod to put the plates way out in front.
The next feature someone needs to develop for the jammer arms is a counterweight system to help them adjust up and down the rack. I have a set of the Rogue jammer arms that I attached a fitness band to so they are much easier to adjust which led to them getting much more use.
The ones from Amazon are $200 (and that's Canadian $) - That's honestly the most I'd pay for Jammer arms. I think they look way cooler than what people report them to be. I'd say most people I've seen have them report to not even use them.
the evolution of these jammer arms is going from isolated plane of motion, to two planes, to free motion, like were nearly back at freeweights. I give it a couple years til everyone gives up on making these.
The potential benefit of jammer arms over free weights is that resistance curve can be configured to be difficult at the top or bottom. For those who believe in lengthened partials this can be helpful.
Maybe one day one of these big brands can integrate the arms into the functional trainer pulleys to act as articulating arms that use the weight stack.
Yeah, the point of machines that they take away some of the stabilizer muscles. Which can be a bad thing since you want to strengthen those. But can also be a good thing for those wanting to do rehab or just give their joints a break from heavy barbell work. The problem becomes when these jammer arms are so free range of motion then it’s basically just dumbbells at that point. Machines are also specialized to be at specific angles to maximize the movement, these aren’t, and unless you’re familiar with the angles you might put yourself in a compromising position worse than barbell work. I still want a pair of jammer arms 😆 but maybe not free motion style.
These look amazing. As I recall, Griffin was the first to release multi-plane jammer arms before anyone else in the US when they dropped their first version of this
After pretty much falling in love with Jammer arms, everyone kept telling me "just give a few months, that will fade" and I kind of agree only that I still love the basic movements (chest press, shoulders, shrugs, and some rowing). So I almost feel the the over-engineering of these (unless to make them easier to use) I don't think is necessary for what most would practically use them for.
@@time.4174 Crandall is like 3-4 lbs pounds less and rogue is 2-3 lbs more. Prx says 60 but not sure that includes the handle. The crandall lever arms have no rollers so I’d imagine they feel way heavier.
For me, the griffins beat the Crandalls simply because of the pop pin lock in on the rack feature. The way you have to secure the crandalls on the upright with the pin will get extremely annoying especially given the weight of the arms
Looking forward to seeing what you have to say about the Crandall Fitness version. Didn't know about this company until I saw their AMA on the HomeGym Subreddit. I live in El Paso, TX. So, I might take a look at their showroom.
Yes, I want to see your review of Crandall. I want to know how burdensome it is to wrestle the crandall trolley up and down, and if its new 1" only holes work with 5/8" racks. Good review on the griffin. I've seen several jammer reviews now, and I'm convinced most are overbuilt, needlessly. I"m convinced the average home gymer is not a musclehead who doesn't mind wrestling with gear before they do the lift, nor someone who pushes heavy. Where's the lighter more agile gear for most of us normal (or older) dudes? Not unsafe gear, but lighter within reasonably safe limits that most of us lift in?
Hello, avid subscriber here! I thank you very much for your reviews which have helped me make a more educated decision when buying some of the products you’ve recommended. However, when talking about jammer arms, I see that those you recommended are made for 3x3 uprights. Unfortunately, the uprights on the smith machine I bought when building my home gym are 2X2 inches and unless I find adapters/jammer arms that would fit them, I’ll have to continue ignoring the jammer arms as a form of exercise I would really like to try. Changing the smith machine at this point is impossible for me: I’m a 64 year old partially disabled (eye sight problems) and this, my budget is limited. My smith machine (ER Kang bought on Amazon) came with jammer arms, but they do not have the adaptability features you talk about and, therefore, are a pain to use. Do you know of any adapters/jammers arms I could purchase to match my machine? Your advice will be greatly appreciated. Thank you! Tirso
I've owned the 1.0 version of these for over a year and I will only say that they are sufficiently "Awesome." Only advice is that "IF" you can, install them on their own dedicated rack...
17:08 I have the first gen of these and i agree there needs to be more holes and they are heavy. I have them on a vulcan and they fit snug to the rack, I also have the magnetic pins and ive never had an issue with the magnets coming out. I think you should check out the Vulcan jammer arms they look promising and at a lower cost than other companies.
@@joenikiforakis5829 dunno either. But remember that there is a HUGE benefit to being able to clamp your favorite bar with your favorite knurl into the smith clamps. And to then make them independent of each other, as well as be able to use them as a trolley with cable (so it basically replaces the Dialed Motion system). I think the versatility justifies the extra cost. His jammer arms will be able to lock into 3, 2, or 1 plane of motion. To be able to have the handles EXACTLY as to what feels right to you is 100% worth it. To be able to play with all the angles and not be forced into one boring fixed set of handles is worth the expense (although I may rethink that if the price is too high but Larry seems to keep the prices fair). I really want to know what the cable isolator is gonna cost. I’ve been eyeing that ever since I saw the prototype rendering.
@@jasonmckinney3876 Where did you see the prototype rendering? The VTS is really overpriced at $900. The Isolator is $800. These are discounted prices already. I can't imagine their lever arms costing less than $2k. I've seen the handles and they're legit but also I don't see many people taking the time to make micro adjustments to the handles. They'll probably be like $400 too.
Don't get fooled folks, bought some cheaper jammer arms and now I just have two belt squats. These all look nice but are a waste of money for the majority! Stay yoked folks
@@djf41393the fringe sport mammoth has a “special” on the mammoth belt squat right now where it comes with the much needed kickstand for $250…. With no taxes charged to California
I thought these would be great for bench where I like to use a neutral grip and bring my hands closer together at the top. But my press kind of sucks (tops out around 160 or so) and the initial weight of these appears to be kind of high (but it is a lever so it's hard to tell). But realistically I might be pushing things trying to use with with a half squat rack (Titan 3X) and they would really take up a lot of room in my tiny gym...
Can you do an update, even in a Short, showing the Jammer Arms being used with the other set of holes meant for Metric racks? This review doesnt do these justice if we can't see it used as Griffin intended
@@time.4174 I've been looking around at different handles and stuff for the Jammer arms. Most handles I found are at least 20 lb. So the Jammer arms weigh about 50 lb. Almost makes sense that they weigh as much, almost as much as a barbell with how much weight they have to hold. It seems like the key is to get Jammer arms that have rollers, so it's easier to slide them up and down the rack.
Some are saying the Crandall Fitness arms are better than these but the Crandalls locking feature is so much worse than these. With these you have a pop pin on the trolley that automatically pops into place on the rack when you find the desired hole but the crandalls have a pin that you have to slide in manually and I can see this getting annoying when you can’t find the hole all the time and because they’re heavy. For me, the way the Griffins pop into place is a feature that can’t be overlooked and is high on my list of jammer arm must have features.
I'm not a patent expert, but from what's being said, PRx may not have an enforceable patent if the invention was already part of "prior art". It's bad form for them to knowingly file a patent for an invention that already exists, and I would guess that it would not hold up in court.
I am betting rep is hitting the streets with an updated arm soon... their arms are on clearance now along with their other "outdated" version 1 equipment...
"I just wish there was a more budget friendly option to try" Ever hear of Amazon? They have really cheap options. $120-$180 jammer arms. The $180 set doesn't look terrible.
Still not sold but this looks like a good step in the right direction for jammer arm Stans. Waiting to see if Bulletproof Fitness comes out with something to push the category forward
Patents can be problematic sometimes, chinese company will not respect your patent, you spend a lot of time and energy fighting it. PRX should keep the patent for a year or two, then allow other companies to use it for a percentage.
There is so much hate on jammer arms, it's honestly shocking given how versatile they are. If you bought them and don't use them that's all on you for being lazy not because they're not useful.
Don't get why people are upset with PRX patenting a good design. That's the lay of the land, it's how capitalism works. You build something cool and you protect your interests with patents. Then other companies find creative ways around the patents, and often come up with better designs. Capitalism (within an IP regime)! Love it or hate it, it works for innovation.

So you’re saying on a rack like the Rep PR4000 we should use the second set of holes and it wouldn’t wobble?
