EAST MOUNT Twister 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.

I would have given this five stars IF they had included some detailed example exercises that worked specific body muscles. Yeah, they showed some obvious ways one could use this, but it would have been nice if they provided specific exercises for specific muscle groups. This is the only reason I didn't give it 5-stars.That said, overall this is a very good product! I found that this puts tension on specific back and chest areas that my other exercises don't focus as much on. I have included this product into my weekly strength training exercises (twice a week) because of what areas it can focus on. And, with the ability to increase or reduce the level of difficulty, this is a tool I expect to use for a long time to come.

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.

This device is awesome. My mother loves using it, I love using it and especially the teens love using it. It has multiple resistant settings and you can definitely feel the burn while using it as well as the next day. What a great handy device. You can do it while working out or even while watching TV. I would recommend standing while using this so that you get the most strength from your core. It’s fun and worth the money.

So, I just recently received mine about two weeks ago. I will tell you that this is no toy. You can make this thing challenge you physically in as many ways as you can think of, within reason of course. It’s an upper body device that is so versatile that it covers a lot of what you need some kind of a gym for. I love this thing and would recommend it. Just buy one. You will be hooked.

This seems to be a well made product however, it seems to cause me some significant pain, after about 2weeks of use, in the medial elbow region, not exactly sure how to describe this region. After about a week of non use, pain is almost gone.

I bought this for something to keep me moving while I was traveling. The first one I got I was unable to adjust the tension at all. I tried for a couple days then emailed the support email (on the back of the instruction book that comes with it) worked with them sent a short video showing the problem and they sent a new one toy door two days later. No need to return the broken one, just threw it out. Excellent customer service and the device does what it says it does so no complaints here.
