This is a pretty cool tool that you can chuck it in back of your car to get a workout anywhere. I will personally be using the Gripedo in a sand bucket for warm up and working for time. I believe it can prevent elbow issues and can help with imbalance issues in the forearm. It is quite difficult to on the grips. The sand training works grips, fingers, wrist, forearms and working with it increases endurance and gives a huge pump in the forearms. This is a very clever design and useful method of training for supination and pronation training for rehab and prehab for elbows and the wrist as well. I am a big fan of wrist rollers and gripedo allows single hand exercises with the nice ball shape handle and you will fell it in your hands really quickly, it works really nicely and allows exercises that are hard to mimic in gym. It is a very versatile device and it is a very clever design. I am a fan of this and implementing in my training.
