Working out alone can result in confusion with complicated machines, wimpy wanderings on the treadmill, and Funyun breaks between push-up sets. Bring back the buddy system with today’s Groupon: for $75, you get three 45-minute personal-training sessions at Fitness Together (a $225 value).

The certified muscle tutors at Fitness Together help students to determine training goals and develop a custom workout plan designed to target self-selected fitness metrics. Shape up for intramural debuts with sport-specific training, sizzle away calories as part of custom weight-loss programs, or bulk up before no-holds-barred dissertation defenses. In addition to workouts, trainers also share nutrition advice, aiding exercisers with healthy grocery guides and access to a library of body-friendly recipes. Workouts unfold in Fitness Together’s full gym replete with cardio equipment, strength-building weights, and communal and private training bays. Stow personal effects in the gym’s well-appointed locker room, which offers temporary shelter to bags, changes of clothes, and inspirational cutouts of Charles Atlas.
