Training effectively by using enough weight to sufficiently overload a muscle, micro trauma and micro tears are created in the muscle. The muscle then goes about repairing itself, and to do so the body uses many resources to make this rebuilding a reality. One of the resources it uses is the body's own natural human growth hormone.
