Perform the exercises as a circuit, completing a set of each in turn and resting as little as possible between sets. Repeat for 10 circuits (until you’re doing only one rep per exercise).

Reps: 10 to 1 Rest: 0 sec.
Stand with feet shoulder-width apart and squat down about halfway. Jump as high as you can. Land with soft knees and begin the next rep. Perform 10 reps. Each time you repeat the circuit, perform one less rep. So the next round you’ll do 9 reps, then 8, and so on, down to 1 rep.

Reps: 10 to 1 Rest: 0 sec.
Hang from a pullup bar, jungle gym, or tree limb and pull yourself up until your chin is higher than your hands. Start with a 10-rep set, performing one fewer rep per set in each circuit as described in the jump squat.
