Things that, when combined, instantly spell disaster: cocktails/unlocked BlackBerry, leggings/granny panties, John Mayer/journalists.

Cardio and Pilates, on the other hand, are a match made in heaven.

Consider the full-body conditioning you’ll get with the Mighty Sport classes at posh new Laurel Heights studio Mighty Pilates. The hour-long sessions meld cardio interval training with weights, spring resistance, and classic ab work. The Mighty Mix class, meanwhile, works students on both the reformer and tower, and there are also beginner, abdominal, and prenatal options.

If you need more personalized attention, there’s semiprivate or individual training with expert instructors.

Until your body is a wonderland.
