Beats a Tennis Ball

By Shane O'Donnell Ranked #17 - Climbing Accessories and Training May 3, 2009

This little trainer has helped me a ton. In the time since I got it I can notice a vast improvement in my climbing endurance, being able to hold on a lot longer. It keeps me occupied in times where I have nothing to do, or if I'm in an airport or class or where ever. It helps warm up my muscles on the way to the project, either during the drive or the approach.
