Answer 1

The GHD Back Extension is a CrossFit exercise targeting the posterior chain. It involves hinging at the hips on a GHD machine while keeping the spine neutral, then raising the torso back up through contraction of the glutes and hamstrings. Key points of performance include maintaining a neutral spine, core engagement, proper breathing, and preventing back overextension.

Step-by-step explanation:

The GHD Back Extension is an exercise used in CrossFit to strengthen the posterior chain, which includes the lower back, glutes, and hamstrings. To properly perform a GHD Back Extension, follow these steps:

1. Position yourself on the GHD machine with your feet secured and hips slightly off the pad.
2. Starting with your body in a horizontal position, initiate the movement by hinging at the hips and keeping your back straight.
3. Lower your torso towards the ground while maintaining a neutral spine, and stop when your body forms a 90-degree angle at the hips.
4. Raise your torso back to the starting position by contracting your glutes and hamstrings.

Primary points of performance include maintaining a neutral spine throughout the movement, engaging the core, breathing correctly, and avoiding overextending the back at the top of the movement.
