After your workouts, massage your muscles with the Triggerpoint The Grid X. The sweat-resistant foam roller stimulates the circulation of blood and oxygen so that your muscles recover faster and you have less muscle pain. Put the roller on the ground and roll over the surface with different muscle groups to exert pressure. After use, take the compact Triggerpoint foam roller with you easily. You can use the hollow interior space to put your water bottle or rolled up clothing in order to save space in your bag.
