STI - Rumble Roller
STI - Rumble Roller - 31" Blue STI 36-inch Rumble Roller relieves muscular pain and tightness. STI Rumble Roller is the one and only deep-tissue roller. The RumbleRoller Manipulates Soft Tissue - Like a Massage Therapist! The surface of the RumbleRoller contains specially designed bumps that are firm, but flexible, much like the thumbs of a massage therapist. As you roll over the top of the RumbleRoller, the bumps continuously knead the contours of your body, gently stretching soft tissue (muscle and fascia) in multiple directions. This action erodes trigger points, helps restore flexibility, and brings quick relief to common types of muscular pain. By design, the RumbleRoller's bumps are firmer than muscle tissue, but much softer than bone, so they deflect out of the way if they contact your spine or other bony protrusions. Through simple techniques, you can control the amount of pressure the bumps apply to your body. The bumps are closely spaced to one another (less than 2" apart), so several of them simultaneously contact your body during most exercises. However, with a slight shift of your body, you can reduce your area of contact with the RumbleRoller, which increases pressure and provides deeper, more penetrating relief. Common Foam Rollers Compress Soft TissuePhysical therapists,  trainers, and athletes use foam rollers to relieve muscular pain and tightness (often called "adhesions", "knots", or "trigger points"). But conventional foam rollers have smooth surfaces that further compress soft tissue. Rolling on top of them improves blood flow and tissue flexibility, but the effect is limited and relatively superficial, unless you spend a lot of time rolling. The RumbleRoller was created to perform this therapy more effectively. Add Another Dimension to Your Foam Roller ProgramThe RumbleRoller's massaging action can be further intensified by changing your movement from a back-and-forth rolling motion to a side-to-side rocking motion.
