Like the framework of a mighty skyscraper, the core helps humans hold up the weight of the sky. Stay firm against the firmament with today's Groupon: for $59, you get two 50-minute private Pilates lessons at Springboard Pilates (a $130 value).

The experienced instructors at Springboard Pilates bolster cores in individualized sessions that challenge students' muscles on both mats and machines. Under an instructor’s careful guidance, torsos and limbs learn new muscle-toning movements to help push themselves to better fitness during a 50-minute private session, acclimating to Peak Pilates equipment including the Reformer, the ladder barrel, and the Wunda chair. When teamed with mat work, these resistance contraptions expand pupil's repertoire of gut-crunching moves beyond sit-ups and playing the board on Monopoly night. Springboard's staff customizes all classes to account for student's goals, past injuries, and aversion to spring-loaded machinery stemming from traumatic childhood slinky experiences. Nestled in an 1846 townhouse, Springboard’s studio warms tense joints with red walls and decorative fireplaces. Patrons can flex and furrow thoughtful brows along with physiques by viewing gallery pieces from local artists.
