GHD Sit-Up

How to do it

1. Sit on a glute-ham developer platform with your hips just past the edge of the pad and feet secured under the rollers, knees bent about 90 degrees.
2. Cross your arms over your chest or place your hands lightly behind your head.
3. Slowly lower your torso back, letting your hips extend slightly past horizontal for a stretch.
4. From the bottom, drive with your hip flexors and brace your abs to pull your torso back up to sitting.
5. Keep both the descent and ascent controlled to protect your lower back, then repeat for reps.
