No plans for Valentine's Day? Now you have one: Punch your ex. Well, kind of. Take out your relationship frustration, aggression and the rest of your pent-up emotions on other embittered boxers in Crunch Gym's Ex-Factor class. Sure, boxing is a huge stress reliever (and calorie-torcher), but Crunch takes it one delightful step further by inviting you to bring a picture of your ex to tape to a focus mitt so you can finally give him the proper knockout you've always fantasized about. Crunch gyms in New York, Los Angeles, Atlanta, San Francisco, Chicago and Miami are offering this free class to both members and non-members. (Pink gloves provided by Everlast.) Here's to you getting fit -- and even -- all in one beautiful day.
