While your spending got slim and trim, your tummy puffed up like a new bride. Damn those greasy dollar menus. Here’s a cheap fix: Fit 214, an under-the-radar personal training school that recently opened on the Katy Trail. A male and female trainer back the Uptown fitness studio, which offers small hour-long group classes (four peeps max) for $24 a head. Sessions use basic — or “primal,” as one owner puts it — equipment in the no-frills gym. Cardio is simple but effective: Think squats, push-ups, and pull-ups. On nice nights, workouts take place on the large outdoor patio, and the instructors send the class for a sprint down the Katy. Nothing like rubbing shoulders with a skinny bitch for some much-needed motivation. Here comes the pride. Fit 214, 3136 Routh Street, suite 3 (214-557-1588 or fit214.com). Through June 30, mention DailyCandy and get three classes on the house.
