How to perform it

Step-by-step instructions

1. 01Lie face up with a resistance band looped securely under both feet and hold one end in each hand with the arms reaching overhead.
2. 02Start with the legs long, press the lower back gently toward the floor, and draw the ribs down.
3. 03Curl the head, shoulders, and upper back from the floor as the knees fold toward the chest, keeping even tension on both sides of the band.
4. 04Bring the chest toward the thighs without kicking the legs or pulling with the neck.
5. 05Extend the legs and lower the torso and arms under control until the shoulder blades and heels return to the floor, then repeat.
