Racked Side lunge

Muscles worked: quads, glutes, hamstrings

Stand tall with your feet hip-width apart holding a pair of dumbbells “racked” in front of your shoulders (palms back, elbows bent and tucked). This is the starting position. Keeping your right leg straight, chest up, back flat, and core engaged, step your left foot out wide to your left. Push your hips back, bend your left knee, and lower your body until your left thigh is parallel to the floor. Reverse the movement to return to the starting position, and then repeat.

Burpee

Muscles worked: quads, calves, hamstrings, glutes, core (plus pecs and triceps if you add the push-up)

Stand tall with your feet hip-width apart and your arms at your sides. Push your hips back, bend your knees, and squat down, placing your hands on the floor. Hop your feet back into a push-up position. (Optional: Do a push-up, keeping your elbows tucked and lowering your body until your chest is within a few inches of the floor.) Hop your feet back to your hands, and then explode upward, swinging your arms up as you jump off the floor.
