A full-range sit-up on a glute-ham developer machine that allows the torso to extend below parallel, training the hip flexors and core through an extreme range of motion.
Form tips
Anchor your feet securely in the GHD pads before attempting any reps.
Only extend as far back as your flexibility allows — overextending at the lower back is a common injury.
Build up range of motion gradually over multiple sessions; going all-out on your first session causes extreme soreness.
