3. Reverse Lunge and Swing
Hold a dumbbell in front of your chest. Lunge back with your right leg as you rotate to your right and swing the dumbbell to your right hip. Then push back to a standing position as you swing the dumbbell to eye level. Repeat to the left. That's 1 rep.
4. High-Knee Run
Stand tall and run in place as fast as you can. Drive through the balls of your feet and try to bring your heels up under your backside so that your knees go high. Keep your hands relaxed, elbows bent, and shoulders down, and swing your arms back and forth.
