Medicine ball rebounders are like small trampolines that have different angle settings so that you can throw a medicine ball and have it bounce back to you. Medicine ball rebounders are great for individual throw-and-catch exercises and they can be used with both bouncing and non-bouncing medicine balls. The Plyoback Reflex Pro has 8 angle settings. The Economy Rebounder adjusts anywhere from 0-60 degrees and has ball storage behind. The Shuttle Rebound has 9 angle settings. All the rebounders can be used for in-place jogging when flat.
