4 sets of 4 repetitions of step ups. Between each set do the push ups. You end up with 16 total reps of steps ups in this workout.
I’m trying to interpet this:
… Just use a lighter barbell for the box step ups. Then rest 2-3 min stretching and repeat 3 more times. Use mountain boots for all. Repeat couplet 4 times
So is that 4 sets (4 steps + 4 push-ups) X 4 or 16 sets (4 steps + 4 push-ups) X 16 ?
