Setup

How each one starts

  2. Engage your core muscles and lift your knees towards your chest, bending at the hips and knees.

Decision

Which should you choose?

The Assisted Hanging Knee Raise reduces the load so you can own the movement before going unassisted. The Flag needs no equipment and scales through leverage, tempo and reps. 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 Assisted Hanging Knee Raise better than the Flag?

Neither is universally better — both train the abs as the primary mover. The Assisted Hanging Knee Raise reduces the load so you can own the movement before going unassisted, while the Flag needs no equipment and scales through leverage, tempo and reps. Choose based on your equipment and which movement you can progress consistently.

Can I do both the Assisted Hanging Knee Raise and the Flag 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 Assisted Hanging Knee Raise and the Flag work the same muscles?

The primary muscle is the same: the abs. Supporting muscles differ slightly — hip flexors for the Assisted Hanging Knee Raise versus obliques and shoulders for the Flag.
