A.T. Nader (March 27, 2008) This medicine ball is exactly what I was looking for. Its relatively small size combined with the heavy weight is ideal for my purposes. I use it in boxing training to simulate receiving the impact from body blows (weight transfer etc.).My students get the feel of receiving the blow without suffering the bruising and soreness encountered in actually taking a body punch... The strike and return also serves as a plyometric exercise.
