Sprint workouts, sub 3 minutes, I find are required hardest to write for CrossFit gyms because of the wide range of skills, strength, and conditioning the members of a gym may contain. It is even more difficult if it is a couplet workout because if one movement is not up to par for an individual, then it’s likely.
The sprint couplet above worked out well for general population for a few reason. Both movements are low skill and the barbell was at a lowish intensity. Also the combo of movements together worked out really well to not overly tax any specific muscle group.
Burpee: hip flexion & upper horizontal pressing
Clean & Jerk: hip extension $ upper body vertical pressing
