Rather than following a medicine ball ‘routine’ as such, a more appropriate approach is to select a few exercises and incorporate them into a circuit or session designed to increase power and/or strength endurance.
Medicine ball exercises are an important tool for developing sport-specific power. They can be used as part of a circuit training format or plyometrics program. In fact, upper body plyometric exercises are limited without their use.
Strength training for sport, for the most part, is very different from bodybuilding. While a phase of the strength training program should focus on maximal strength development and occasionally hypertrophy, it is explosive power and/or strength endurance that should be the end-goal for most athletes. While there are various methods to increase power, a common element is speed of contraction. Medicine balls are relatively light allowing exercises to be performed explosively.
