This workout combines significant volume (4 rounds) with moderate-heavy thrusters and continuous work creating substantial fatigue accumulation. The 1k rows will elevate heart rate before hitting 20 thrusters at 95/65 - a weight that becomes challenging under fatigue. Double unders after leg-heavy movements add coordination difficulty. The combination of cardio, strength, and skill with minimal rest between elements pushes this into Hard territory for average athletes.
This workout develops the following fitness attributes:
This workout consists of 4 rounds of 1000m row, 20 thrusters (95/65), and 30 double unders. I'll analyze this by breaking down each movement and applying fatigue multipliers across rounds. Movement Analysis (Fresh State): - 1000m Row: 195-270 seconds (3:15-4:30) - 20 Thrusters (95/65): 40-60 seconds (2-3 sec per rep) - 30 Double Unders: 15-30 seconds (0.5 sec per rep in rhythm) - Transitions: 3-6 seconds between movements Round-by-Round Breakdown: Round 1 (Fresh): Row 240s + Thrusters 50s + DU 22s + Transitions 12s = 324s Round 2 (1.1x fatigue): Row 264s + Thrusters 55s + DU 24s + Transitions 12s = 355s Round 3 (1.25x fatigue): Row 300s + Thrusters 62s + DU 27s + Transitions 12s = 401s Round 4 (1.4x fatigue): Row 336s + Thrusters 70s + DU 31s + Transitions 12s = 449s Total for L5 athlete: 324 + 355 + 401 + 449 = 1529s (~25:30) This workout is most similar to Jackie (1000m row, 50 thrusters 45/35, 30 pull-ups) but with significant differences: heavier thrusters (95/65 vs 45/35), fewer thrusters per round (20 vs 50 total), double unders instead of pull-ups, and 4 rounds instead of single effort. The Jackie anchor shows L5 at 420-480 seconds, but this workout has 4x the volume and heavier loading. Scaling from Jackie: The thruster load is roughly 2x heavier (95 vs 45 for males), and we have 4 rounds vs 1, suggesting roughly 3-4x longer times. Jackie L5 of 450s × 3 = 1350s, which aligns well with my calculated 1529s. Final Benchmarks: L10: 840s (14:00) - Elite athletes maintaining strong pace L5: 1320s (22:00) - Average CrossFitter with moderate pacing L1: 1980s (33:00) - Beginner with frequent breaks and slower transitions
Three movements across all modalities: Row (monostructural cardio), Thruster (weightlifting with barbell), Double-Under (gymnastics bodyweight coordination skill). Equal distribution with slight emphasis on weightlifting.
| Attribute | Score | Explanation |
|---|---|---|
| Endurance | 8/10 | Four 1k rows combined with continuous movement creates significant cardiovascular demand, testing aerobic capacity throughout the workout. |
| Stamina | 9/10 | High volume thrusters and double unders across four rounds will severely test muscular endurance in shoulders, legs, and grip. |
| Strength | 4/10 | 95/65lb thrusters require moderate strength but emphasis shifts to strength endurance rather than maximal force production. |
| Flexibility | 6/10 | Thrusters demand good overhead mobility and ankle flexibility, while rowing requires hip hinge and thoracic extension. |
| Power | 7/10 | Thrusters are explosive hip-to-overhead movements, double unders require rapid coordination, and rowing demands powerful pulls. |
| Speed | 6/10 | Maintaining consistent pace across all movements and minimizing transitions between row-thruster-double under becomes increasingly challenging each round. |
