Sorry for the late post. 13 hr difference throws me off.
Max reps of Muscle-ups in 4 minutes (sub = 3 pullups/3 ring dips per muscleup)
The Tabata interval is 20 seconds of work followed by 10 seconds of rest for 8 intervals. Tabata score is the least number of reps performed in any of the eight intervals. Begin time for muscle-ups immediately after the last 10 second rest interval. Test score equals Tabata score multiplied by number of muscle-ups completed.
Here’s a Video of CrossFit legend Greg A. doing this WOD. His hip extension gets a bit short in his squats (not standing up fully), but I wouldn’t tell him that to his face.
