Endurance | 5/10 | While primarily a gymnastics skill test, performing 100 muscle-ups for time will have a significant metabolic impact, especially if sets are large or rest is minimal. |
Stamina | 10/10 | Extreme test of upper body pushing and pulling stamina, as well as grip endurance, to complete 100 muscle-ups. |
Strength | 8/10 | Muscle-ups require significant relative upper body strength for both the pull and dip components. Maintaining this over 100 reps is a huge strength-endurance feat. |
Flexibility | 5/10 | Requires excellent shoulder and wrist mobility for efficient muscle-ups, particularly the transition and dip phases. |
Power | 7/10 | The kip and transition of a muscle-up are highly explosive movements. Maintaining this power for 100 reps is a key challenge. |
Speed | 4/10 | Efficient cycling of muscle-ups is important, but managing fatigue and avoiding failure on such a high-skill, high-volume task is paramount. |
