Start: Lie with back on an exercise mat, arms at sides, knees bent at a 90-degree angle, feet flat on mat.
Move: Slowly lift hips and lower back off mat, squeezing butt as you lift, until you form a diagonal line from knees to shoulders. Hold position, lift left foot off mat, straighten leg, then slowly sweep it out to the side as far as you comfortably can. Return leg to center, place foot back on mat, then lower body to start position. Switch legs to perform on right side.
Repeat: 8 to 10 repetitions per leg
