Going to the gym is a safe way to work out, unlike doing streetlight pull-ups or fighting public-disturbance charges. Lift lawfully with today's Groupon: for $25, you get 12 passes to Fitcorp (a $190 value). This Groupon is valid at all six gym locations. Today’s Groupon expires 90 days after activation, and it must be activated within three months.

Fitcorp whittles bodies with a sweat-inducing smorgasbord of personal training, fitness equipment, and group exercise classes. Six area locations host a legion of cardio and weight machines for exercisers crafting their own regimens or perfecting impressions of treadmills for an Off Broadway production. Each gym also hosts group exercise classes led by experienced instructors for clients of all stripes and schedules.

Both the Financial District and One Beacon Street gyms teach Group Power, a barbell-centric class that toughens muscles with lunges, squats, and studded leather jackets. For patrons seeking a cardio pump, most spots host Boot Camp, Cardio Challenge, or Burn, an advanced session that challenges über physiques with military-style drills and calisthenics. Each location’s schedule varies; check individual gym calendars for class styles and times.
