This is your final chest workout of the strength phase. By now, you know it well. But do you know what you're capable of in it? Next week everything changes, so make this count!
For these workouts, don't take your warm-up sets to failure. Then, choose your working weight so that you reach failure by the target rep. Take 2-4 minutes of rest between sets, which will allow for both muscular and central nervous system recovery.
When you're done, be done; don't insert additional movements into the workouts. Just make the most of the moves you're doing. If you want to do your 30 minutes of cardio directly after this session, fine. Just don't do it right before lifting, and don't do it on three consecutive days.
