SQUATZ Twister Bar Arm Exercise - Home Chest Expander, Adjustable from 22-440lbs with 2-20 levels, Anti-slip Ergonomic PU handle, Home Fitness Resistance Equipment Bar for Men and Women

PSA for everyone, this exercise tool can be very dangerous. Please wear the included wrist strap while using. Last week I had this slip and it hit the bottom of my chin HARD. I was lucky, I could have ended up in the hospital, but all I suffered was some temporary pain on my chin and jaw. I do love this exercise tool and continue to use it every day. But please stay safe. I am giving it 5 stars since it became my favorite exercise tool where I can squeeze in some reps throughout the day and feel like my upper body is being challenged every time. I prefer to use this while seated than standing. Helpful tip: You can balance your arm on your leg to make it easier by using some leg assist, but don't cheat too much.

This thing is ABSOLUTELY INSANELY AMAZING way beyond my expectations, because I had a similar one?but it was piston and the resistance wasn't very strong.But word to the Wise, I didn't read the directions correctly make sure you put your hands through the straps because if you don't this thing Will Literally Knock You TFO it slipon me twice both were my fault because I never knew what the straps were for? The first time it slipped it hit the bottom of my chin and busted my lip open on the inside, lessen learned NOPE I was using this about a hour before last Thanksgiving and this time it hit my chin so hard it bust the bottom of my chin wide open, my top teeth left left embedded marks on my bottom lip blood was everywhere it took nearly 2hrs for it to completely stop bleeding i probably should have gone to get stitches but it was Thanksgiving and I have a goatee so it didn't show where it had busted open. All of this being said it's amazing you get a crazy good chest workout & pump, I Definitely Recommend but don't be a mada head like me 🤪 Make Sure You Put Your Hands Through The Loops because if you don't i 100% GUARANTEE YOU THE SAME THING WILL HAPPEN THAT HAPPENED TO ME, and when I say it was like getting kicked in the chin by a horse I 100% GENUINELY MEAN THAT!!! This thing can be Seriously Dangerous!!!! Maybe that's why this item says it's no longer available.

Once you get comfortable with the tension adjustment process and set it, you can get a great upper body workout!

You can definitely strengthen your pecs with this device and it's solidly constructed and likely to last for a long time, especially because there is no hydraulic cylinder to leak, there is a heavy duty spring instead. The device handles are strong plastic, I'm ok with that, but some apparently find them uncomfortableIt's easy to alter the resistance on this device by turning the knurled knob near the bottom.All that being said, there are three main issues I have with this exercise machine:1) Though it's easy to alter the resistance, it's extremely difficult to reset the same resistance again unless you leave the setting as is between uses. The problem with that is if you want to fold the device up to stow away, you have to dial out the resistance to let the arms come together.2) Turns of the adjusting knob produce inconsistent and unpredictable increments in the resistance, it's very difficult to gradually increase resistance via fixed increments over time, especially in view of issue #13) Altering the resistance changes the range of motion through which you work the muscles, there is a very small arc of motion at lower resistances and a very large arc at the higher resistances. I feel that you should be able to work your muscles through a full range of motion at any resistance levelIf you want a sturdy, durable device capable of providing a great deal of resistance and don't care about the issues I've outlined, then go for it.

Been sick for last 6 months and lost 35 lbs and my skin on arms was getting loose from muscle loss. Seems to be helping build muscle back

The directions are terrible, at least call the sections by the same title for starters. Thr glove, which isn't a glove but rather a wrist strap, is the size for my 10 yr old daughter. No matter how I adjust the device, the arms are super close together and my 4 year old (I have a few kids) can squeeze together or any larger distance apart I can barely budge. I know I'm a weakling at 6'1" 190lbs and can bench 315 and squat 495 lbs. but who is this built for, Thor the God of Lighting? Sending back tomorrow morning.

Outstanding, but with recommendations:1) Wear leather gloves, especially when reaching maximum resistance levels. The hand straps will cut into your wrists when increasing maximum resistance levels. Unfortunately, the grips are not well ergonomically designed with the hard plastic versus rubber; and2) Make sure you apply controlled pressure on the rebound after each compression.In closing, I prefer a spring apparatus versus a hydraulic power twister because you feel each compression more and there is no leakage of hydraulic fluids.

Easy to use and adjust, doesn’t break (the hydraulic ones are bad about it), suggested to my brother
