Short answer
Ab Roller vs Ab Machine: An ab roller is a small wheel you roll out from the knees or feet: hard, compact and less costly than a machine. An ab machine guides a crunch-like movement on a track, with levels to progress, but needs floor space.
Key takeaways
- Rollers are hard, small and cheap.
- Machines guide the movement and add levels.
- Many people start on a machine and add a roller later.
