EAST MOUNT Twister Arm Exerciser - Adjustable 22-440lbs Hydraulic Power, Home Chest Expander, Shoulder Muscle Training Fitness Equipment, Arm Enhanced Exercise Strengthener.

This is a great little workout equipment. My husband asked me to order it, but I have been using it since I opened the package. Comes ready to use with thorough instructions on the safety lock, how to adjust, which resistance levels are recommended for whom, and different exercises you can do. Very clear cut and easy to understand. They have resistance level recommendations for teenagers, women, and multiple levels for men or stronger people. I have used it at level 4 and can feel it working my muscles in my arms, shoulders, chest, and back. Tightening the core gives a nice boost to the movements. I like that it has a soft return after you squeeze the handles inward. It does not jerk back which would be dangerous. Instead, it has a slowed return kind of like a soft close cabinet. I also like that the grips are comfortable and easy for my smaller hands to hold. It doesn’t put stress on my arms in an uncomfortable way like other similar equipment pieces do. I know my husband is going to love this when he tries it. However, he might have to pry it out of my hands first.

This workout machine is great, but the fact that I use it so much and do 300 reps at 10 to 12 weight, and eventually completely snapped and I needed to order a new one which they gave to me for free. I can absolutely see this machine breaking again, simply because I use it so much and the weight is just too heavy for it not to break. It is made very well, but with the amount of strength needed to push about 3000 reps a week, I just cannot see how it won’t keep breaking over and over again. I absolutely love the machine and love what it’s doing to my body and getting me stronger, I just think that it needs to be made a little stronger because I can definitely see it. keep breaking over and over again. But I will definitely keep using it. Definitely a great product.

So far this thing is great. It is very sturdy and absolutely works the muscles. Mostly for chest but you can work biceps and triceps pretty easily. I regularly do push-ups and pull-ups, rows etc... After 2 sets of 10 with the setting on 2, I was sweating. The settings go to 20! I'm not weak and this thing really zeroes in on the muscles and works them. I would recommend for any home gym. 4 stars instead of 5 because I think if the handles were adjustable length, it would be that much better.

This is for all the lazy couch potatoes or skinny computer geeks out there. There are various videos on youtube showing how to workout with this thing; they only take a few minutes to do. You will see gains with this. That being said this device is probably only useful for beginners or people that have tried to workout in the past but burn out quickly. Experienced body builders aren't going to have much use for this due to weight limitations. What makes this great for rookies or people that don't like to work out in general is that you don't have to swap to different pieces of equipment. You will feel each workout and it really does hit your chest very well. It takes time to master but once you get it down spending just 15 minutes a day with this will give you some results. Don't expect to be some sort of body builder with this thing but if you are the type of person that is doing nothing anyway this will help improve your physique. You will notice a difference in your chest for sure.

Arrived on time with some other exercise stuff I got for girlfriend she says it really works your arms it is very sturdy I only have it on 2 you can tell that it is working my arms you definitely get a good arm workout with it and I can see a little difference in my arms already just in a few weeks using it

A simple effective easy-to-learn and use device is ergonomically designed and provides comfortable but also very thorough strength training to any and all muscle groups in a standing or sitting posture which is crucial if you have high blood pressure or stroke risk. Better than dumbbells and about as good as cables. You could use this up to a very decent fitness level including increases in size BECAUSE YOU’LL DO IT, unlike other training options more time consuming. This lies on my kitchen table. 15 reps through 5 different exercises once a day. Increasing resistance as I get stronger. Really a game changer for me. Doc Johnson

For me, this was not a "muscle builder". It is just a useful tool for some "in-house" exercise. It certainly works well, is of good quality, and seems to be durable. I'm sure the heavier settings would be good for those looking for some help with body building.

I bought this for a light-weight way to do some upper-body resistance maintenance while traveling. This packs nicely into a bag, that was my intended use. I started keeping it next to my computer desk for the same reason and using it while thinking or while waiting for computer things to happen. This turned out to be a mistake (for me). I'm a relatively "fit" guy you might say (I use 40lb free-weights regularly and I run several times a week - I'm not 'johnny-workout' but I'm also not entirely inexperienced) so I was not expecting to have a problem with this device. It isolates and works the muscles you expect it to but the unintended consequence is that it absolutely murders the tendons in your wrists and elbows. Tendons. Not the big guys you work out regularly, the little guys that connect the bones to everything else. And it creeps up on you, days or weeks later. There's a reason, I think, that the chest machine at the gym does not involve your wrists & elbows. It's entirely possible that I'm "doing it wrong" and I'm willing to concede that if someone else has found an effective way to make this a part of their daily routine I'm not going to tell them that they're lying, but the way that the device is ergonomically designed led me to operate it in a fashion that felt damaging to the connective tissues that you're really not supposed to strain that way. I hold heavy stuff at weird angles sometimes for hours at work so I don't think that I'm one of those guys who isolates a few cosmetic muscle groups and neglects normal mammalian balanced "connector" muscles in favor or some kind of aesthetic (I don't look or want to look a guy who works out solely for the aesthetic) so I don't think I'm having problems with this device because I'm 'unbalanced' in that way. I don't really "work out" like your average gym-rat now that I think about it, I get much of my 'workout' done on-the-job. Either way, I figure that I probably have enough experience to identify a "good hurt" vs. a "bad hurt". Good Hurt: Sore, exhausted, but energetic (and give it a little time and it'll want more). Bad Hurt: Shooting pains, tender, wants to stay at rest; all movement feels bad. Maybe it's just user-error, but this thing generated a lot of those bad hurts and I just ended up quitting it. I still think the build-quality is solid (although I had to loc-tite the nuts myself - not that big of a pain) but I'd use with caution: I think it's easy to damage yourself with this device, regardless of prior muscle-tone and experience.
