Move Targets: Core
Sit down with legs straight ahead. Pull the belly button into the spine, creating a scoop in the lower belly. Roll your back down slowly with arms extended out in front of you. Tuck your chin as you roll. Stretch your arms over your head so you're completely extended on the floor. Keep your feet together and on the floor.
Roll up with control. To reverse it, move your arms over your shoulders. Then begin to roll the first few vertebrae off the floor with a scoop in the lower belly again. Keep your feet on the floor! Think about lengthening them and squeezing through the inner thighs.
Straighten your posture. At the top of your sit-up, open the chest and straighten the spine by sitting tall. You can stop here and go back into the roll, over lean over and touch your toes.
