For 15 minutes:
10 Pull-up/ KTE combo*
50 Double-unders (or 150 high knee jumprope)
Count rounds and completed half-rounds for score.
*1 pull-up + 1 knee-to-elbow= 1 rep. Work hard to make the transition between them as smooth and efficient as possible.
Knees-to-elbows. Knees to triceps, and also the frequently seen “knees to thin air”, are different, much less challenging exercises.
