The other issue is the workout turns into an aerobic exercise not a muscle building exercise. For a decent leg workout it takes me 1.5 to 2 hours...try doing curls, squats, presses, extensions, stiff legs, etc in 45 min...good luck. Most upper body workouts can be done in 60-75 min depending on strength levels.
