Weighted balls are an efficient and multifunctional training tool that can be incorporated into strength, conditioning, and sport performance programs. They provide instability and rotating difficulty that fixed equipment or traditional free weights do not. This develops core strength, coordination and explosive power simultaneously. Weighted balls can be used for many different training goals and fitness levels, from moderate rehabilitation movements to high-octane throwing and slamming activities. Compact, sturdy, and versatile, these devices are a worthwhile addition to any home gym, studio or commercial training space.
