Hydration isn’t the only recommended post-workout move. Using a foam roller to give yourself a deep-tissue massage can improve mobility and speed up the recovery process after you’ve pushed your body to the limits. Kill two birds with one stone courtesy of the Water Bottle Roller, a 25-ounce water bottle clad in a high-density foam sleeve that allows it to function as a roller for those sore muscles. Plus, the insulated double-walled bottle keeps your drink cold even in warm, sweaty gyms. Hydrate, roll, and repeat your way to better health and mobility.
