Workout of the Day
5 rounds:
1:30 of step ups (unweighted)
1:30 of calories
1:30 of rest

Settle into a steady pace on the step ups, and then push hard on the machine; you’ll definitely be getting more step ups than you are calories, but there’s a pretty hard upper limit on how fast you can go on them. Avoid getting into the range of inefficient diminishing returns on the step ups, and instead apply that extra energy to the machine in the second 1:30 of work.
