The Grid 2.0 foam roller is ideal to roll through tight muscles, knots and kinks that prevent you from feeling good and moving well. Its ergonomic size allows for decrease in strain during full body use, and provides more coverage for your whole back. The different zones of the roller work very well especially for those muscles that take a lot of work to soften up. And the grid pattern allows tissues to relax as you roll, which promotes local blood flow which carries nutrients needed to repair muscle. Constructed from quality materials that won't break down or lose shape from repeated use, it is firmer than a basic foam roller, allowing you to use more pressure and work out deep knots or tension better. Includes access to video instruction for the foam roller to target specific spots and muscle groups. Use the Grid 2.0 after a long run in the mountains!
