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

Got this on sale so it was a good price for what you get, would I buy this at full price tho? Yes I would. It’s a really simple design that uses an oil filled piston that has a knob used to restrict the flow of the oil making it more or less resistant. What’s interesting about this design is they managed to balance the pressure of both sides equally so you don’t over work one side or the other. It’s fairly compact so you can take it anywhere in a backpack or something, but it is a little heavy. The movement of the levers is smooth and offer a good balance and feel. One thing I would have changed is the handles, they tend to get a little slippery after a while when your hands start sweating. They could have made the handles have grooves for your fingers making it easier to grip. Also the little clip on the bottom to hold the handles together for transporting could of been attached to the handle by a small hinge or something making it nearly impossible to lose, but you do get extras so at least that’s nice. Overall this simple device offers a nice easy upper body work out that you can feel after a while, my arms and chest were soar the next day so it’s a good sign it’s working. I would definitely recommend this for people who work at a desk or sit a lot through the day, it’s a good way to work out without having to stand if you can’t or don’t want too.

Years ago I was going to the gym, I wasn't able to Target the muscles that I wanted to. I tried various equipment with no results. This device is targeting the exact muscles that I want to build. I started off using the six sitting because I wasn't sure where my muscles were. 2 months later I've bumped up to 14, I'm doing sets of 20, 25, 20 and it's pretty brutal. It's total resistance during the entire compression, feels like using heavy duty bolt cutters trying to cut through rebar. I definitely recommend this, I am able to compress it on the highest setting, but only once and it's harsh. Not getting any dye rub off on this one, there were a lot of complaints about other similar devices leaving dye on hands and clothes. No issues with hydraulic leakage so far, if it comes up I would probably buy another one.

Really great piece of equipment, just don’t go too crazy with it. The screws on my mine became loose after about a month of using it and it fell apart. Had to figure out what was wrong and just tighten up the screws again. Other than, it’s a solid piece of gear I highly recommend.

Granted I’ve only had this for two days now, but this was an amazing investment. I remember seeing it months back thinking it was too good to be true and ordered some dumbbells instead to work out at home with. However, since I’ve been more consistent at the gym, I would need to order new weights at this point and they aren’t very portable.I work security and have some shifts exceeding 14 hours depending on the day. I can get pretty stir crazy at work and I wanted something that would get me results while on the clock. I did the same thing with forearm trainers back at my old job. I went browsing again and saw this device, and with all the great reviews I figured at this cost it was worth a shot.I can say with full confidence after a mere 8 reps per exercise in each position (also adding in a bicep variant where I have the device against my shoulder) I can feel myself getting a pump after my first set. Knowing I can easily transport it and store it aside at work, use it for quick workouts when I have downtime, and feel the burn after very little use… I’m confident I’ll be seeing excellent results in no time.I can also tell it will be long while before I am strong enough to get up to the highest settings. I get better engagement than with weights and a stronger contraction than cables. It won’t eliminate my upper body days, as cables provide more stretch tension and weights are better for stabilization, but as a way to exercise at work I can say I don’t think there is a better option out there.

I'm over two months in. I use it daily, no set amount of reps or anything just what I feel like in the moment. Typically stay between 12 and 16 with a few 18s here and there. Level 18 gives me tennis elbow after 3 reps though. My chest and neck are toning and shaping up nicely and in a quick amount of time with some visible gains too. It's an impressive piece of equipment for how little it cost. Sturdy and simply built but if I do break something on it, I would have zero problems with buying another one.

This is a beast of a home gym tool! The hydraulic resistance feels smooth, and it really targets chest, arms, and shoulders. Great for quick, effective workouts at home. Adjustable tension is a big plus. Compact yet powerful—perfect for building upper body strength without bulky machines.

Will this make you huge ah no will it maintain and is it a quick easy work out heck yeah! I am an older guy so this is great for me to just keep the blood bumping and keep my chest an arms in good shape. Easy to use and works great

This is the 2nd one of these I've purchased. The other one was another brand, but almost identical to this one. I just love the simplicity and convenience of this thing. I keep one in my desk at work and one at home. Have 5 minutes? Break this out and fire off 3 sets. It's not going to replace a whole routine, if that's what you're looking for. But if you just wanna keep toned up and keep your blood flowing, this is a great purchase. Folds up nicely and takes up very little space.
