You are still focusing on increasing the volume of work you do in your workouts. As we increase the volume of your workouts you are going to try and reduce the rest times. The goal is to use weights that still challenge you in the workouts, but not allow for a full recovery before you start the next set. You may have to reduce the weights from set to set. You should be breathing very hard in these workouts.
NOTE: You will start seeing improvement in lean muscle mass, fat loss, movement pattern condition and in overall body efficiency.
