A leg stretcher is a training device that allows the user to stretch his or her leg muscles easily and more efficiently. The ProForce Stretchmaster features a padded seat and leg rests to help you stretch further than ever before while remaining comfortable. It’s highly durable and can be used in your home gym, dojo, or wherever you train for martial arts. You can also try the Flex-a-Tron III steel leg stretcher, which is completely portable and includes a center handle bar plus two leg extensions. Leg stretchers are useful training equipment for karate, boxing, MMA, and other martial arts.
