Abstract

The present invention is a separable weight adjustable medicine ball, which can be used in a variety of exercise routines. The present invention is primarily comprised of two pieces, which can either be separated to perform exercises that involve dumbbells or push-up handles or be combined to perform exercises that involve a medicine ball. The present invention allows a user to incrementally increase the exercising load with a plurality of weights. The plurality of weights is separated between the two pieces and held in place with a pair of weight supports. The plurality of weights is secured on the pair of weight supports with a pair of collar clamps. The collar clamp is an user-friendly device that can be opened by squeezing the sides of the collar clamp and can be closed by releasing the sides of the collar clamp.
