Stimulus and Strategy:
Today’s workout is a moderate-duration chipper. Expect the box jump-overs with the higher box to exhaust your legs and make the air squats more difficult. Keep moving through the air squats, even if your legs are tired from the box jump-overs. If needed, slow your pace, breathe, and keep on moving. The combination of box jump-overs and air squats will also likely make the start of the run more difficult. Plan to get yourself moving, find a rhythm, and empty the tank to finish strong.

Intermediate option:
For time:
30 box jump-overs
120 air squats
1,200-meter run
