42.5kg thrusters are light-moderate (roughly 95lbs, ~65% of bodyweight for average athlete), and 15 reps is manageable volume. Pull-ups at 15 reps per round create grip fatigue but are fundamental. The 3-minute rest between rounds is substantial recovery, allowing athletes to reset. The main challenge is thruster-to-pull-up transition and cumulative grip fatigue across 3 rounds, but most average CrossFitters complete this as prescribed without scaling. Total time ~15-20 minutes with built-in recovery makes this accessible.
This workout develops the following fitness attributes:
The primary limiters are thruster cycling at 42.5 kg and pull-up grip endurance across 3 rounds with 3-min rest; L5 (~6:30 total) breaks thrusters into sets of 8-7 and kips pull-ups in 2-3 sets per round. Times reflect cumulative work time across all 3 rounds only (rest excluded).
Thruster is a weightlifting movement (barbell with external load). Pull-Up is a gymnastics movement (bodyweight). Two movements split evenly across two modalities.
| Attribute | Score | Explanation |
|---|---|---|
| Endurance | 5/10 | Three rounds of moderate-intensity work with 3-minute rest periods between rounds provides moderate cardiovascular demand. The rest allows recovery, preventing sustained aerobic stress. |
| Stamina | 7/10 | Thirty thrusters and thirty pull-ups across three rounds challenges upper body and leg muscular endurance. The cumulative volume and fatigue carryover between rounds stress sustained output capacity. |
| Strength | 6/10 | 42.5 kg thrusters represent moderate load relative to bodyweight. The weight demands significant force production, though not maximal effort. Pull-ups add bodyweight strength component. |
| Flexibility | 4/10 | Thrusters require shoulder mobility and hip flexibility. Pull-ups demand shoulder and thoracic mobility. Demands are moderate; not extreme range of motion required for execution. |
| Power | 6/10 | Thrusters are inherently explosive movements requiring rapid force generation. Pull-ups can be cycled explosively. The for-time format incentivizes powerful, quick reps over grinding. |
| Speed | 6/10 | For-time format encourages fast cycling and minimal rest between movements. Athletes must balance speed with sustainability across three rounds. Transitions between thrusters and pull-ups matter. |

A grindy aerobic engine builder — sustainable pace with clean transitions, not a sprint.
Pace your first round 5–10s slower than feels easy. Break the gymnastics before failure — small sets save big time across rounds.
Reduce the barbell load to maintain unbroken sets on the cleans. Sub jumping pull-ups or banded for HSPU.
