How each one starts
Butt-Ups — first steps
- Lie flat on your back with your knees bent and feet flat on the ground.

- Place your hands on the handles of the wheel roller and extend your arms straight out in front of you.

Which should you choose?
The Butt-Ups need no equipment and scale through leverage, tempo and reps. The Wheel Rollout loads the core through a long, controlled range. 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.

Common questions
Are the Butt-Ups better than the Wheel Rollout?
Neither is universally better — both train the abs as the primary mover. The Butt-Ups need no equipment and scale through leverage, tempo and reps, while the Wheel Rollout loads the core through a long, controlled range. Choose based on your equipment and which movement you can progress consistently.
Can I do both the Butt-Ups and the Wheel Rollout 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 Butt-Ups and the Wheel Rollout work the same muscles?
The primary muscle is the same: the abs. Supporting muscles differ slightly — hip flexors and lower back for the Butt-Ups versus lower back for the Wheel Rollout.
