Review on Wisdompro Hand Grip Strengthener Rings - Improving Finger And Forearm Strength For Climbing And Workouts by Brandon Peters

Sample provided at discount or no cost for evaluationThese are hard rubber that doesn't have any strong odor, that was an immediate bonus. If you're trying to strengthen your hands, either out of self interest or because you're recovering from injury or surgery, these definitely will help. The green one is the easiest and that's as stiff as I could ever use because I'm weak. But, I kept it in my desk drawer and would take it out several times a day to use and noticed after 2 weeks, my hand was a lot stronger (I only tested on my right hand because I had a very serious injury to my right index finger which accounted for the weakness). My handwriting improved because I was able to hold a pen better. I was actually pretty surprised that, after months of expensive physical and occupational therapy on my finger after my injury that seemed to do nothing, this inexpensive little rubber ring made an almost immediate difference.So, these turn out to be great for strengthening if you have arthritis or some sort of weakness or injury in your hands, or if you just want a better grip. The green is the easiest, then blue and finally orange. Good quality and easy to throw into a drawer for storage in between use.
