| Endurance | 7/10 | Seven rounds of high-rep double-unders and a moderate barbell complex (deadlifts, hang power cleans, front squats) creates a significant metabolic demand, testing skill endurance and cardiovascular fitness. |
| Stamina | 8/10 | Cycling 71 double-unders per round (total 497) tests calf and shoulder stamina. The barbell complex (14 DL, 6 HPC, 9 FS at 135/95 lb per round) demands significant grip, back, leg, and shoulder stamina. |
| Strength | 6/10 | The barbell load (135/95 lb) is moderate, but performing 29 total reps of varied lifts per round for 7 rounds tests strength endurance significantly. |
| Flexibility | 4/10 | Requires mobility for deadlifts, hang power cleans (front rack), and front squats. Wrist/shoulder mobility for double-unders. |
| Power | 6/10 | Hang power cleans are an explosive movement. Double-unders have a plyometric component. Maintaining power in the barbell complex under DU fatigue is key. |
| Speed | 6/10 | Efficient cycling of double-unders and the barbell complex, with quick transitions, is crucial for a good time. |
