This workout comes down to managing muscular fatigue. It is set up to go from pulling to pushing to cardio in order to allow athletes to keep moving through at a high intensity. However, within each set we want to avoid reaching muscular failure. When athletes feel like they are nearing that point, switching out to one of their partners will get a fresh body working and allow them to recover. 5 is a good number to aim towards on pull-ups and 10 is a good goal for bench press and the bike or rower, but athletes should also listen to their bodies in order to come back strong for the next set.
