This will blast your forearms. I feel my grip strength has improved significantly. I used Vaseline to lubricate the ball joint after I noticed some squeaking. I tried using a silicone based lubricant but it quickly started to squeak at high resistance. Make sure you use petroleum jelly for maintaining it

tarda mucho en llegar y llega por correo corriente, los materiales son de calidad y su funcionamiento es simple pero efectivo, el manual de usuario está en ruso asi q recomiendo ver videos en yt para diseñarse una rutina de uso, llevo un par de semanas con el y me siento muy bien usandolo

It is THE BEST thing I've tried for hand, wrist, forearm, shoulder blade connection and strength. Exercises go right up the chain to the shoulder blade. Honestly the best rotator cuff exerciser I've tried and it's not billed primarily as a rotator cuff exerciser!It primarily strengthens the hands and forearms. Like the devil. So simple, VERY mechanically solid construction. Hundreds of applications. Easy to do a bit now and a bit later - 3-8 minute stints before your forearms cannot do anything more. It is uniquely effective and it's almost immediately obvious as soon as you begin using it.I've had it less than two weeks and I'm honestly amazed at what it's done in that time. At times, when I'm done my 7 mins or so on it (I do this 2-3 times per day for 6-8 minutes per session just going through some of the exercises from the Russian only pamphlet that comes with it) my shoulders are sore. I've gotten some minimal development of my rear delt with it and certainly any upper back muscles are more toned, more stable, and stronger.If you have hand problems, wrist problems, or shoulder problems, I would HIGHLY recommend you look at this or any of the other models of Sotsky Bison trainers. I'm so shocked this is a secret. I don't think there is anything out there that is better for developing grip strength from the core out to the palms.That said, this won't work your FINGERS in all ranges of motion as well as the Bison 2 looks like it will. Or this Bison 1 with flat handles would be great for fingers. After using Bison 1 for 2 weeks I'm pretty sure I'll end up also buying it with flat handles, and also buying Bison 2 for fingers specifically.But what this doesn't do for fingers specifically it DOES do for wrist, forearm, and shoulder girdle. It's been a lifesaver and a godsend and I'm so surprised that this isn't more well known. Everyone should have this as part of their workout to be honest. There is nobody who can't improve their work with this. One massive bodybuilder on a Russian YouTube channel said he was able to stop using lifting straps after 1 month using this. I have no doubt it does a lot more than that.I am fixing a series of old injuries that had become almost predatory to my peace of mind and enjoyment of life - from a wrist injury that turned into a forearm imbalance, that turned into a shoulder girdle/rotator cuff dysfunction. And it's getting into ALL those muscles most remarkably, quickly, and consistently.My shoulders feel way more relaxed, stable, and ready than they did 2 weeks ago and I've been working on them for years. I really feel that 2 or 3 months of this for 10-20 minutes daily will work miracles.I'll stop raving now but I'll say it's worth twice its price, is long overdue, is amazingly effective, and that if you're trying to figure out if to buy this the answer is YES, emphatically. It's well worth the wait (takes a month and a half to arrive) and it's well worth the money.You won't find much in English about this or this company, or its inventor in the Internet but the guy who invented it deserves a nobel prize. There, I said it. Oh, and he can bend 9 inch nails into knots. That's not a joke - look up Sotsky's Nail. They don't do a lot of English marketing but this thing is amazing.

I really love this!! It works superbly well. It absolutely works out the hands, wrists, and forearms. And it is built really well. Happy I bought it. Thank you Sotsky's.
