Runner’s Lunge to Knee Skip
Start in a pushup position, then bend your left knee and place your left foot between your hands (a). Push through your left foot, raise your torso, and drive your right knee and left arm into the air, hopping off the ground (b). Return to start, then switch legs and repeat on the other side. That’s one rep.

Quarter-Turn Squat Jump
Lower into a squat, then jump up, swinging your arms overhead and rotating 90 degrees to the left while in the air (b). Lower into a squat, then jump up and rotate to the right. That’s one rep.
Start in a pushup position, legs extended directly behind you and hands under your shoulders (a). With your legs together, brace your core and glutes, then kick both legs into the air, bending your knees to bring your feet toward your butt (b). Reverse the movement to return to start, trying to land softly on the balls of your feet. That’s one rep.
