CAP Barbell's 8-lb rubber medicine ball is a classic fitness tool that has been used for decades to develop strength, coordination and endurance. This new version is designed with a tacky grip for easy hold, and it bounces for partner or wall exercises.
I bought this to help with a maintenance program to keep off about 38 pounds I lost earlier in the year. It has become a mandatory tool in my exercise arsenal. I use it for sit-ups, twists and tosses. I like it a lot.
