This workout has a 20-minute cap with 1400m run followed by AMRAP. Breaking down: 1400m run takes 6-10 minutes (elite: 6 min, intermediate: 7.5 min, recreational: 9 min), leaving 10-14 minutes for AMRAP. Each round contains 20 Double Unders (10 sec), 6 Toes to Bar (12 sec), 4 Burpee Pull Ups (16 sec), totaling 38 seconds fresh. Adding transitions (5 sec/movement = 15 sec), each round takes 53 seconds initially. With fatigue: Round 1-2: 53 sec, Round 3-4: 58 sec (1.1x), Round 5-6: 64 sec (1.2x), Round 7-8: 69 sec (1.3x), Round 9+: 80 sec (1.5x). Elite athletes (14 min AMRAP time) complete 2 rounds (106 sec) + 8 rounds at increasing times = ~11 total rounds. Recreational athletes (10 min AMRAP) complete fewer due to longer transitions and more fatigue. Grip fatigue from Toes to Bar significantly affects Burpee Pull Ups, adding 20% time penalty after round 4.
