Is this workout just simply to build your endurance to lift weights? Does it help get muscle definition at all? I am wanting to get more cut and am having a hard time deciding what workouts to do weekly. I am doing a bootcamp class 2x week that has you alternating cardio with weights.she usually has you do 15reps,3 sets but I usually do another wt workout on mine own at home and want the maximum results. In class I lift as heavy as I can then drop down in wt if needed. thanks
