The Grid 2.0 foam roller is ideal for rolling through tight muscles, knots, and kinks that prevent you from feeling good and moving well. Constructed from quality materials that won't break down or lose shape from repeated use, it is firmer than an essential foam roller, allowing you to use more pressure and work out deep knots or tension better. Its ergonomic size decreases 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, promoting local blood flow, which carries nutrients needed to repair muscle. Includes access to video instruction for the foam roller to target specific spots and muscle groups. Use Grid 2.0 after a long run in the mountains!
