Step by step instructions
Lie face-up with legs at a 90-degree angle over hips, knees pressed together and bent, and feet lifted. Reach arms by sides of hips, palms facing down. Engage abs to lift head, neck, and shoulders off floor, lowering legs slightly as upper body lifts.
Extend legs and lift torso off floor, bending elbows behind body at shoulder level and squeezing shoulder blades back and together so body resembles the letter "V." Bend knees and extend arms back out by hips, gently rolling down through spine with head and shoulders lifted to return to start. (Modify by keeping legs bent or holding onto backs of thighs to help you sit up.)
