How each one starts

  2. Place the band around the arches of your feet and hold the ends of the band with your hands.

  2. Lower your torso backward with control; shorten the range while learning.

Decision

Which should you choose?

The Band Lying Straight Leg Raise gives accommodating resistance that peaks at the top of the range. The Ghd Sit-Up fixes the movement path so you can push close to failure with less skill demand. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the abs adapting.

Answers

Common questions

Is the Band Lying Straight Leg Raise better than the Ghd Sit-Up?

Neither is universally better — both train the abs as the primary mover. The Band Lying Straight Leg Raise gives accommodating resistance that peaks at the top of the range, while the Ghd Sit-Up fixes the movement path so you can push close to failure with less skill demand. Choose based on your equipment and which movement you can progress consistently.

Can I do both the Band Lying Straight Leg Raise and the Ghd Sit-Up in the same program?

Yes, but usually not in the same session — they overlap heavily on the abs. A common setup is one as your main movement and the other on a second training day, or alternating them block by block.

Do the Band Lying Straight Leg Raise and the Ghd Sit-Up work the same muscles?

The primary muscle is the same: the abs. Supporting muscles differ slightly — hip flexors for the Band Lying Straight Leg Raise versus minimal assistance for the Ghd Sit-Up.
