I suffered a serious injury to the index finger on my right hand (and I am right-handed). I was looking for something to help strengthen it without being boring, repetitive and something that would actually be useful when I stumbled across the Dynaflex pro. I wasn't quite sure what it was, but I gave it a shot anyway. When it arrived, at first I was very confused as to what to do with it. I understood the concept of a gyroscope but not how it worked within this ball. The directions weren't that helpful so I searched online for a video hoping maybe someone could SHOW me how to use it. That wasn't much more helpful, but I'm a determined person and kept trying to figure it out. I couldn't understand WHAT it was supposed to be doing. I could see there was a heavy, magnet-feeling weight to it and something that rattled inside (think of a heavy cement marble inside of a slightly larger plastic ball and what it would feel like if you were trying to get it to spin around using centrifugal force). Everything I tried frustrated me because I could NOT get it started. It comes with a red string, that sort of looks like a shoe string and the directions did say if you can't get it "started" (still not sure what that meant at the time), you could insert the string in the hole located on the yellow part (see the photo), wrap it around and give it a pull - similar to those toy cars where you insert the long, plastic strip and give it a yank it get it started zipping across the floor. So, I followed the directions, pulled the string and felt a weight against my hand. I got a good grip on the ball in the palm of my hand and sort of flippled my hand palm up/palm down, working against the weight to make it spin. What happens is, the weight (inside of the yellow part) begins spinning (sort of like I described with the marble I assume) and goes faster and faster, requiring you to have a stronger and stronger grip on the ball. You can feel the muscles all the way up your arm into your shoulder beginning to work, the faster it spins, the more difficult it is to hold! I then tried transferring it to my left hand and realized it had to make it spin the other direction. In the end, it was the perfect thing to strengthen my finger (I had accidentally sliced my tendons & arteries, nearly severing my finger) to the point where I can type this review, hold a pencil and my surgeon was amazed at my quick progress. It's also a great way to work your biceps and triceps and strengthen your wrists. It's about the size of a tennis ball, maybe a bit smaller. Maybe I'll find some time to make a video review to help anyone who needs that little extra "something" to get it started. This is a great toy, portable exerciser or perfect for OT/PT and recovery from injury as well.

fonctionne bien

Im currently deployed to Afghanistan and dont get the chance to go to the gym as often as Id like. One of my friends back stateside had the metal dynaflex and I thought it was cool but couldnt see spending the money on it. Since I get bored in my little off time, I figured Id finally man up and buy a dynaflex. I opted for the cheaper version and figured it wouldn't be a total loss if I couldnt get it working. Its taken me a little bit of time, but after watching some pointer videos on youtube, I can do get the dynaflex going. Its not as easy as it sounds or looks and the string in my opinion makes it harder. The thumb flick trick works well. Overall I see how the dynaflex can definitely help with wrist exercises. I recommend this to anyone who types a lot or just has sore wrists. Your hands get tired pretty quickly once you get it going. Thanks Amazon and Dynaflex. Shipping said it was going to take a month and a half to reach Afghanistan...it took 5 days. Needless to say I was really excited when it got here after being told it would take forever. Buy it but dont give up on learning to use it.
