FIITY 8/12 Pounds Resistance Adjustable Rotator Machine for Upper Body Strength Training, 360 Degree Rotating Grips, Multifunctional Spinning Burn Machine for Forearm Trainer, Boxing, Workouts

Great resistance, strength, stretch & tone device. 8lbs is enough for this 70 year old grandma. It has improved my upper back stretch extension and released stiffness. Love it!!

Be warned, if you dial up the resistance this is a truly challenging workout. It's not just a whimpy product for novices. This is the real deal, and with the proper resistance setting it can fully exhaust your shoulders and arms in less than 1 minute. Repeat 3 or 4 times and you're going to be cashed out for the day.You can also dial the resistance down and use this for warmup (which is what I do). The different ways you can use this are great to keep forearms and wrists strong and preserve mobility.I would buy this all over again. If fitness and strength are a part of your life, then I would highly recommend adding this to your workout equipment, especially if you want a lot of value from something that fits in a small space.

I am using these daily with dumbbells and martial arts training and they really build muscle. I saw online that The Detroit Lions weight training program and The Worlds Fittest Man both include them in their workouts. You do have to search online for the best exercises, but to me they're great. I only use the kind with resistance because that was part of what I want them for, building up punching power. I would think any boxer or fighter would gain from using them regularly.

it's really good quality the sad thing is You can't take it apart to oil. Or greece the ball bearings Inside the unit.

I'll be 70 years old next year. I'm very fit since I've worked hard at it for a long, long time. I wanted to accomplish the following at a minimum:- Isolate shoulders- strengthen forearms- strengthen grip- portable equipment I could travel withThe Rotator Machine checks all the boxes and engages abs, back and related upper body. And, the fittest man on Earth, Mat Fraser - 5x Cross Fit Games Champion calls this his secret weapon, check out his video. I bought the 12lb and the 8lb.The 12lb is a beast. I use it in front of me and lower for arm work.. The 8lb is no joke, I use it raised and overhead for shoulder work. The 18lb is likey too much for all but the biggest arms out there. You'll exhaust your muscles very quickly,Build quality seems excellent. Fit and finish are impressive. Get one...or like me, two.

Better than expected if you think this is expensive you're wrong. This is a high quality device that works my muscles differently and better than anything else. It's heavy though so if you cannot pick items with weight don't buy it. I am trying to prevent carpal tunnel, I already have tennis elbow. I went back to working out body building again and I noticed my hands were going numb during the first treatment of the day. Huge disconnect from your client, everything so far seems to be helping. Great addition to my equipment so far.

The thing is not bad when it works. It lost resistance on one side which makes it useless. I tried to contact the seller but didn't get any solution. Now it's an expensive paper weight. It's a shame. Wanted to love it. If it worked I would love it. Meh. Waste of money.

This product is excellent for upper body exercise. I use it every day and the adjustable resistance is a plus.
