How each one starts

  1. Lie flat on your back with your knees bent and feet flat on the ground.
  2. Extend your arms straight out to the sides, parallel to the ground.

  2. Lie flat on your back with your knees bent and feet flat on the ground.

Decision

Which should you choose?

The Alternate Heel Touchers need no equipment and scale through leverage, tempo and reps. The Assisted Sit-Up reduces the load so you can own the movement before going unassisted. 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

Are the Alternate Heel Touchers better than the Assisted Sit-Up?

Neither is universally better — both train the abs as the primary mover. The Alternate Heel Touchers need no equipment and scale through leverage, tempo and reps, while the Assisted Sit-Up reduces the load so you can own the movement before going unassisted. Choose based on your equipment and which movement you can progress consistently.

Can I do both the Alternate Heel Touchers and the Assisted 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 Alternate Heel Touchers and the Assisted Sit-Up work the same muscles?

The primary muscle is the same: the abs. Supporting muscles differ slightly — obliques for the Alternate Heel Touchers versus hip flexors for the Assisted Sit-Up.
