This 12-minute AMRAP breakdown: Round analysis - Power Snatch (135/95): 2-3 sec per rep fresh, scaling to 4-5 sec under fatigue due to heavy load and technique demands. Chest-to-Bar Pull-Ups: 1.5-2.5 sec per rep fresh, scaling to 3-4 sec with grip fatigue and shoulder pump. Calorie Bike: 15/12 cals take 18-25 sec fresh, scaling to 25-35 sec as legs fatigue from squatting movement in snatches. Transitions: 3-8 sec between movements. Round-by-round fatigue: Round 1 (100 sec), Round 2 (110 sec), Round 3 (125 sec), Round 4 (140 sec), Round 5 (160 sec), Round 6+ (180+ sec). Major limiting factors: grip strength from snatches to pull-ups, shoulder endurance, and heavy snatch load causing significant CNS fatigue. Elite athletes complete 7+ rounds, average CrossFitters 4-5 rounds, beginners 2-3 rounds with potential scaling needed.
