#7. Thigh raises
Start on your side with your legs extended, flexing both feet. Place your top hand on the ground in front of your abs and your supporting arm under your head. Make sure your bottom leg stays extended for the duration of the series. Keeping the energy reaching out through your flexed heels, lift your top leg up about six to eight inches from the floor. From here, make tiny pulses upward 20 times. Holding your leg at the highest point of your lift, draw one-inch circles with your heel for 20 reps. Keeping your top leg lifted, bend and straighten your knee. Do this 20 times while not letting your thigh lower as you press through the heel to lengthen your top leg to the straightened position. For an even greater burn, finish this series with lifts in a bigger range of motion, taking the foot all the way toward the ceiling and back down, 10 to 20 times.
