Brighten Up and Get Outside With Our May Must Haves

My weekly Barry's Bootcamp addiction means I'm nursing sore muscles a lot, so the Sklz Cold Roller Ball ($40) has become a welcome addition on my desk. The ball glides easily over my sorest spots, and it's small and portable, which means I can throw it in my bag to take with me anywhere. Bonus: the roller ball contains an insulating gel that holds a cold temperature for hours, so I can pop it in my freezer, go out for a long run, and come back home for some much-needed recovery that helps my muscles stay loose and keeps injuries at bay.
