FOAM ROLLERS MERELY COMPRESS MUSCLE
When you roll on a conventional foam roller, a compressive force is
generated. The amount of compression depends on the
size of the contact patch between the roller and your skin. For a
typical 6" diameter foam roller, that contact patch is large, so the
amount of compression is small and the effect on deeper tissues is very
To counter this limitation, athletes often progress to smaller and
harder rollers, or even PVC pipe. A downside of that approach is that
rollers don't conform to the shape of your body. While they may have
the intended effect in some areas, they don't work well around bony
- e.g. your pelvis, spine, and scapula.
RUMBLEROLLERS GO DEEPER
In 2009, RumbleRoller forever changed foam rolling with the introduction of the first deep-tissue roller. It's
high-profile bumps penetrate deeper into the muscle, and large inter-bump spaces provide room for soft tissue displacement.
Furthermore, the bumps' resilience enables them to deflect around bones and get closer than ever to the source of your problem.
LIKE A DEEP-TISSUE MASSAGE
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.
ROCK AND ROLL
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. This
RumbleRoller-exclusive feature is especially useful on dense muscles
(e.g. your calves) and hard-to-roll areas (e.g. your upper lat).
2 FIRMNESS OPTIONS
RumbleRollers don't break down like other foam rollers, but their
bumps will soften slightly during your first month of use. However, keep
that your muscles also become more supple with regular massage and will
require less aggressive care to maintain.
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. So
the firmness that best matches your current needs.
- ORIGINAL (blue): With very firm but flexible bumps, this
model comes closest to mimicking thumb pressure. Great for all body
parts, and works better
around bony areas. Recommended for both beginners and experienced
- 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.
SAFE AND EFFECTIVE
All RumbleRoller materials have been tested by independent
laboratories in accordance with the Consumer Product Safety Improvement
Act (CPSIA) of 2008
for lead and phthalates. The CPSIA considers these products to be safe
for use by anyone, including children. All RumbleRoller products
are also latex-free.
RumbleRoller's smooth, nonporous surface repels most dirt, is
water-proof, and even includes a molded-in antimicrobial additive that
helps prevent the
growth of bacteria and fungus.
LONG LASTING VALUE
RumbleRollers are of unparalleled quality, partly due to extensive
material research and testing. For example, the outer shell of our
molded from a proprietary EVA/polyolefin blend with several times the
strength, tear and abrasion resistance of conventional foam rollers.
Many of our competitors use a hollow plastic pipe for the core of
their roller. That reduces their manufacturing cost, but also
their roller's life. We use only solid high-density EVA foam cores,
because they won't fatigue or crack over time, and provide a deep
resilience that makes
RumbleRoller respond better to your body.
