Whether you’re just getting back into a routine or you’ve been exercising for years, most good workouts come with some kind of sore, achy muscles afterwards. Help relieve some of those aches and pains by sitting in a cold bath (we’re talking around 50 to 55 degrees F; throw some ice cubes in to help get it that cold!) for approximately 10 to 15 minutes. It might be hard to handle at first, but experts swear this helps reduce soreness.
