This routine is a single session that focuses exclusively on working the legs. The workout should take you about 30-minutes to finish. Check out the the other single session workouts that are similar in design to this leg session. There is a back, shoulder, chest and arm & core day which like this session was designed to get you in/out of the gym in less than 30-minutes. Work hard! The program starts with a brief warm-up on a bike (but use any equipment or go for a jog) followed by a single-leg Bridge to activate the glutes for the upcoming workout.
