PRO expands on the ingenious design of Gripmaster providing serious athletes with the most advanced hand exerciser in the world. The PRO features a larger profile, superior steel springs that resist wear, and an integrated ergonomic palm bar for comfort.
PRO isolates and strengthens each finger individually, helping you improve your overall strength, endurance, and dexterity. A few daily workouts with the Gripmaster Pro and you'll enjoy better control of cards, coins or other magic apparatus, with each finger working seamlessly with the others.
To keep things interesting and to accommodate certain uses, the company recommends several different exercises which are explained on the Gripmaster website, prohands.net. Best of all, you can work out anytime and anywhere with the Gripmaster Pro, which fits neatly in your pocket.
In essence it took a good month of two, using this product frequently in order to start noticing a difference. I would walk around with it in my pocket using it no matter where I was, and it has worked wonders for my cardistry and magic. For some reason, performing certain sleights is now easier and holding a palm invisibly is a lot easier.
A great buy!
