The GRID® Foam Roller, the original hollow core roller, features a patented multi-density foam surface that delivers firm compression like a sports massage while channeling blood and oxygen needed to repair muscles. The GRID® Foam Roller is the 'go-to' roller to release muscle pain and tightness, improve mobility, increase circulation, and is recommended by sports doctors, chiropractors, and physical therapists.

• Three-dimensional surface allows tissue to aerate while you roll, promoting the flow of blood and oxygen, the nutrients needed to repair muscles.
• Proprietary Distrodensity zones replicate the feeling of a massage therapist's hands.
• Hard, hollow core hand-wrapped in EVA foam makes it firmer than traditional foam rollers.
• Superior construction won't break with repeated use.
