Climbing Pull Up Power Ball Hold Grips with Straps - Non-Slip Hand Grips Strength Trainer Exerciser for Bouldering, Pull-up, Kettlebells, Fitness, Workout

I use a chinning bar set-up for "standing Pilates," stretching, etc., and these are a perfect addition to that, without getting in the way. Regular hand pull-downs never seemed to give any variation or benefit to the set-up, and would hit me in the face (too long and low). Their description of the change in tendon angle, etc., seems plausible and feels good. Dimpled, golf-ball-type surface was a stroke of genius: good grip without the wear and tear of protruding nibs or ridges on sensitive fingertips.

Works well. Durable. Only wanted to take half star off because they started coming loose after one use. However, a little bit of torque and they haven’t ever since. Possibly because I use them for all varieties of upper movements. Great product!

I love training on these. I'm working on my underhand grip but so far it's been fun. Tested them with 200lbs.

Use them daily in my gym at work. The rubber does give a little bit around the eyelet but overall a great product for a great value. Will have your forearms huge in a week.

I am only able to use them for a short while ... dead hangs and maybe one pull-up. But I am confident they will improve my grip strength and grip endurance. My son-in-law, who does obstacle course racing, tried them out over the weekend and decided he needed to buy a pair.

The power balls are of wonderful quality. They seem like they will hold up over time. These definitely allow an individual to work on hand and forearm strength and I look forward to future days of training with them.

Nice and grippy, can be strapped to a rack, clipped to a cable, even strapped to a barbell for landmine rows and such. ice little addition to the home gym to enhance exercises with some grip work.

After a few weeks of moderate use (pull-ups only), one of the balls peeled apart straight down the middle. I weigh 180 pounds (81 kilograms), so I’m assuming you should be alright if you weigh a good bit less than me if you want these things to last a while.

Perfect thank you

Work perfectly for exercises in the gym where handles aren’t a good solution such a reverse tricep crossovers.

Nice and solid. Works well in the gym!

good very fuctional

Great for bicep & tricep curls/presses. Also , cable chest flys, rear deltoid flys , pronated forearm curls, chin ups , lateral cable single deltoid lifts/raises.
