Bar muscle-ups are a high-skill limiting factor that many average CrossFitters cannot perform unscathed, and programming them alongside a strict/kipping/butterfly pull-up complex, a 1:00 bar hang, and 10 push presses at 115# creates brutal cumulative grip and lat fatigue. The 45-second interval structure with 10 rounds adds time pressure on top of compounding upper-body and skill demands, leaving little recovery between efforts.
This workout develops the following fitness attributes:
5 total movements: Strict Pull-Up, Kipping Pull-Up, Butterfly Pull-Up, and Dead Hang are all Gymnastics (bodyweight, 4 movements = 80%); Push Press is Weightlifting with an external load (1 movement = 20%). No Monostructural movements present.
| Attribute | Score | Explanation |
|---|---|---|
| Endurance | 3/10 | E45SEC x 10 format keeps total work window short, roughly 7-8 minutes. Cardiovascular demand exists but the interval structure limits sustained aerobic stress, making this more anaerobic than aerobic. |
| Stamina | 7/10 | High-volume upper body pulling across strict, kipping, butterfly pull-ups, bar muscle-ups, a 1:00 isometric bar hang, and 10 push presses creates substantial cumulative grip and shoulder muscular endurance demand. |
| Strength | 5/10 | Strict pull-ups and bar muscle-ups demand meaningful relative strength. Push press at 115# represents a moderate load requiring force production, blending strength with technique across the full session. |
| Flexibility | 4/10 | Bar muscle-ups require shoulder mobility and hip flexor engagement for the kip. Butterfly pull-ups demand thoracic and shoulder range of motion. Moderate mobility requirements throughout, above baseline pulling work. |
| Power | 6/10 | Kipping pull-ups, butterfly pull-ups, and bar muscle-ups are inherently explosive, hip-driven movements. Push press adds a lower-body-to-overhead power expression, making power a primary training stimulus here. |
| Speed | 5/10 | The 45-second interval demands efficient transitions and cycling through multiple pull-up modalities without wasted motion. Athletes must manage bar hang time and push press output within a tight repeating window. |
