7. Butt Kicks
Stand with feet hip-width apart, arms at your sides. Squeeze your right hamstring (the muscle behind your thigh) to bring your right heel to your right glute. Quickly return your right foot to the floor, and then bring your left heel to your left glute. Gradually pick up the pace and stay light on your toes as you alternate lifting heels. You can perform this stretch in place or moving forward.
8. Skipping Arm Swings
Stand with feet hip-width apart, arms at your sides. Hop on the ball of your right foot as you lift your right knee so your right thigh is parallel (or almost parallel) to the ground, flexing your right foot. Place your right foot on the floor and immediately hop on the ball of your left foot to lift your left knee. Keep alternating feet to move forward in a skipping motion. As you do, swing both arms out to the sides away from your torso before swinging both arms toward your torso as though you’re giving yourself a hug. Swing your arms back and forth while you skip.
