This is a 3-round workout with 400m run, 21 KBS (53/35), and 15 pull-ups per round. Round 1: 400m run takes 75-120 sec (using 90 sec baseline), 21 KBS at 1.5-2 sec per rep = 31.5-42 sec (using 35 sec), 15 pull-ups at 1-2 sec per rep = 15-30 sec (using 20 sec), plus 10 sec transitions = 155 sec. Round 2: Apply 1.1x fatigue to gymnastics movements due to grip fatigue from KBS and pull-ups = 99+38.5+22+10 = 169.5 sec. Round 3: Apply 1.2x fatigue = 99+42+24+10 = 175 sec. Total baseline time: 155+169.5+175 = 499.5 sec ≈ 500 sec for average athlete. Elite athletes complete in ~7.5 min (450 sec) with better pacing and transitions. Recreational athletes take ~11.5 min (690 sec) due to set breaking on pull-ups and slower running pace. Time spread of ~15% between levels accounts for varying cardiovascular capacity, grip strength endurance, and movement efficiency.
