Multi-layer massage therapy roller with Trigger Treads, an advancement in massage therapy rollers, engages both your upper and lower layers of muscles and connective tissue.  You will find that you are able to reach muscles and connective tissues that were difficult to reach without this tool. You can now do self-applied trigger point massages.  The non-slip grip design offers great leverage to target hard-to-reach areas like back, hip flexors, glutes and hamstrings.  It's the best way to prevent injuries from excessively working out.  You need to assist in the recovery process to ensure that you do not overstrain or hurt yourself.
