By the time I finish my Thursday night Muay Thai sparring sessions, I'm beat - and beat up. The kicks I take to my legs don't always leave bruises, but they still smart. It's also my second workout of the day after a 7 a.m. I need a little something extra to help my sore muscles recover. Lately, I don't turn to ice or compression therapy to soothe my aches. Instead, I've been trying out CBD supplements.
