How Does a Body Build Muscle?
Progressive Muscle Overload For the body to build muscle, the muscles have to be exposed to some type of progressive muscle overload or resistance. Muscle hypertrophy, or muscle building, results when muscle fibers are broken down by weight training or some other form of progressive muscle overload and then repaired by the body. It is this repair process, which includes mending of the broken or torn muscle fibers as well as an actual thickening and growth in their size, that results in muscle being built. The ongoing breakdown and repair of muscle tissue is the process whereby muscles grow bigger and stronger over time. The training, or muscle overload phase, provides the spark that sets the muscle building process into action. Muscle Repair Muscle hypertrophy, or building, occurs after muscle tissue has been broken down by weight training and/or some type of progressive overload that stimulates tearing of the muscle fibers. The body then responds by healing and rebuilding the injured
