GHD Sit-Up Exercise in CrossFit

The GHD (Glute-Ham Developer) sit-up is a common exercise employed in CrossFit for strengthening the core muscles. This exercise is performed on a GHD machine. Here's how to perform GHD sit-ups:

1. Begin by adjusting the GHD machine so that the hip pad is positioned under your pelvis and thighs when you sit on it.
2. Sit on the GHD machine with your feet secured under the foot pads.
3. Lower your torso back while keeping your spine neutral until your body is parallel with the floor.
4. Swiftly sit up by flexing your hips and using your core muscles. Simultaneously, throw your arms towards the ceiling to help with momentum.
5. End the movement by sitting up completely with an upright torso.

Primary points of performance for the GHD sit-up include maintaining a neutral spine, a controlled descent, and an explosive ascent. The goal is to work the core muscles effectively while minimizing the risk of back injury. It's essential to start with fewer repetitions and build up as strength and form improve.
