"This M-Roll Massage Stick ($30) is great for massageing my calves, hamstrings, quads, and glutes after a lower-body workout. I've also used it to roll out my back and neck during the work day when I feel sore from sitting (I'm guilty of being so focussed on my work that I slouch a lot). I'm a fan for sure." — Sam Brodsky, assistant editor, Fitness
