This ascending EMOM muscle-up ladder (1 MU in minute 1, 2 in minute 2... 12 in minute 12) totals 78 muscle-ups. Early minutes offer generous rest, but by minutes 9-12, athletes must perform 9-12 consecutive muscle-ups under significant cumulative fatigue. The limiting factors stack brutally: skill, pulling strength, and grip all degrade simultaneously. Most average CrossFitters will fail somewhere around minutes 7-9, making this a wall workout that demands elite gymnastics capacity to complete as prescribed.
This workout develops the following fitness attributes:
Muscle-Up is a single bodyweight gymnastics movement, making it 100% Gymnastics.
| Attribute | Score | Explanation |
|---|---|---|
| Endurance | 4/10 | The EMOM format provides built-in rest each minute, limiting sustained cardiovascular demand. As the ladder progresses, heart rate elevates, but this is not a pure aerobic test. |
| Stamina | 5/10 | Early minutes are low volume, but the ascending ladder accumulates total muscle up reps. Later rounds challenge muscular endurance in the pulling, pressing, and transition musculature significantly. |
| Strength | 6/10 | Muscle ups demand substantial upper body pulling and pressing strength, particularly through the ring or bar transition. Higher rep minutes in the ladder test strength endurance under fatigue. |
| Flexibility | 5/10 | The muscle up transition requires meaningful shoulder mobility, lat flexibility, and wrist positioning. Athletes without adequate thoracic and shoulder range of motion will struggle with the turnover. |
| Power | 7/10 | Muscle ups, especially kipping variations, are inherently explosive movements. Generating hip drive and rapid pulling power to clear the rings or bar is a primary physical demand. |
| Speed | 4/10 | The EMOM structure requires reps completed within each minute window. Higher rungs of the ladder demand efficient cycling and quick transitions, though rest time reduces pure speed pressure. |
