Tuck Crunch

Setup

1. 01Lie on your back with the knees bent and feet off the floor.
2. 02Hold the knees stacked roughly over the hips, shins parallel to the floor.
3. 03Place the fingertips behind the ears with elbows wide.
4. 04Press the lower back gently into the mat and brace.

Execution

1. 01Exhale and crunch the shoulders up while drawing the knees toward the chest.
2. 02Let the pelvis curl slightly off the floor as the knees come in.
3. 03Squeeze the abs hard at the point of maximum tuck.
4. 04Return shoulders and knees to the start position under control.

Checkpoints

• -Both ends move together: ribs toward pelvis and pelvis toward ribs.
• -The lower back stays in contact except for the small pelvic curl.
• -The neck stays long with no hand pulling.
• -Legs return to the start without the feet touching down.

Common mistakes

• -Only moving the shoulders and leaving the knees parked.
• -Swinging the legs to bounce into each rep.
• -Letting the lower back arch as the legs extend away.
• -Racing through reps and shrinking the squeeze.
