EAST MOUNTTwister 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.

I've been pleased with this purchase. It's portable. You can do several exercises to strengthen you arms and if you're creative, you can use it to do crunches, etc. You can take it with you on vacation or keep it handy at work. It's well made and easy to adjust the resistence.

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 piece of equipment is absolutely AWESOME! The resistance is smooth and HEAVY! This thing will seriously work your entire upper body. chest, shoulders, biceps, lats, etc. This thing is also kind of addictive. I find myself banging out sets on this all day and when sitting around watching TV. It's super portable so you can bring it anywhere. Brilliant in it's simplicity. Five stars from me.

Item arrived in new condition with a very helpful user guide with a list of different types of workouts and the areas/muscles each workout would target. This machine is 100% legitimate and produces results. It's a very sturdy, versatile, and easy to adjust piece of equipment. It's got a wide range of strength settings from a beginner's level all the way to a professional body builder.

It's a quality piece. Made well, works as advertised. But pushups are a better exercise and they're free.

Great for sitting at your desk or watching TV. This thing works better than cable flys. More concentrated and you can do when walking around the house talking on the phone. Build quality is exceptional. Don’t try and fly with it as a carry-on. Even though it only weighs 4.5 lbs they have discretion on anything they believe is over 5lbs.
