“The Ultimate Thigh Exercise — Standing, walk your feet out wider than your hips. Turn your toes out slightly, bend your knees and imagine you’re sliding your back against a wall (no hinging back like a regular squat). Aim to have your thighs parallel to the floor. Reach both arms in front of the body and begin to pulse your legs up and down an inch for 30 seconds. Now, reach arms overhead and continue pulsing for another 30 seconds. Finally, hold at the deepest point of your plie squat and begin to lift and lower both heels at the same time for 30 seconds. Repeat this series three times—embrace the burn (and shakes)!”  From 3 Things Your Fitness Instructor Is Secretly Thinking During Class
