If a sculpted midsection is what you're after, the ab roller can potentially help you get there, considering it seriously works your "six-pack" ab muscles, aka the rectus abdominis. The rollout exercise engages your entire body, not just the abs. The positioning requires a lot of upper body strength and it does require a lot of trunk stability, so it works the lower back as well, and it engages the glutes.
We know, you're not asking for much - just an awesome physique, increased self-confidence, better health, greater strength and a longer life. If you are willing to turn your humble home into your personal war room, we are here to help you find the right home exercise equipment to get the job done.
