RumbleRoller Xtra Firm Rollers are constructed using the same patented series of bumps continuously knead the contours of your body, gently stretching soft tissue in multiple directions and effectively hitting trigger points but on a firmer roller.
Firmer isn't always better. Going too firm jeopardizes your ability to use your roller on all body parts or to relax your muscles fully. This is why we generally advise all first time buyer consider the RumbleRoller Original products as first time purchases. So choose the firmness that best matches your current needs.
XFIRM (black): Extremely firm (about 36% firmer than Original), and only recommended for experienced users with especially dense muscle tissue that doesn't respond to normal massage pressure. This model does dig deeper into thicker muscles, but may be too painful to use on some body parts.
As you roll on a RumbleRoller, its firm but flexible bumps work like the thumbs of a massage therapist to knead and stretch your muscles. This action erodes trigger points, helps restore flexibility, and brings quick relief to common types of muscular pain.
RumbleRoller's massaging action can be further intensified by switching from a rolling motion to a side-to-side rocking motion. The bumps provide a wiping-type massage pressure when rolling, but are more resistant to flexion when loaded sideways, and dig in even deeper.
