Hard to believe, but our prescribed 1x/per week, actually allows your body its natural course to recover and build the long term, sustained strength you desire from a workout. High intensity muscular stimulation taxes the muscle to exhaustion. With an adequate rest period, the muscle will overcompensate for the exertion and grow. In this way, you continue to gain muscular strength and composition. More muscle makes for a more efficient metabolism. Whether you work out presently, or haven’t exercised in years and feel out of shape, this is the safest and most efficient method of working out.
