Powerfingers Hand/Finger Strengthener - Exerciser

These are great for working those hand, finger, and arm muscles in the OTHER direction from the common squeeze tools. I am sure this description is not a medically correct way of putting it, but I think you will know what I mean. I especially like this set, because it has multiple strength-rated units in one small container, making it easy to store and carry. I works exactly as pictured.

Really great tool to help any climber avoid elbow tendonitis by balancing the forearm muscles, make sure you check out some videos so you use it to its full capacity!!

I like them a lot! Very comfortable and nice on the fingers! Unfortunately they started falling apart after 2 month of use. I didn't really do anything out of the ordinary - just used them every other day while driving to work in traffic.

Love the antagonist training for climbing necessary for general maintenance for injury prevention. I have found that it is starting to show signs of wear and that I need to stack multiple rings now. More difficult rings would be an asset.

I got these for my boyfriend as a birthday present and he loves them! He's a rock climber and uses these in the car when he's stuck in LA traffic. Really nice that there are different intensities so he can build up his hand muscles gradually.

I broke my hand and these are helping to strengthen my grip quickly.

my hands are so strong now!

This device helps strengthen and realign my arthritic fingers to be able to play the flute.
