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 $25, you get a five-class pass for Pilates and/or yoga classes at Imprint Pilates & Yoga on Spadina Avenue (an $80 value). The five classes must be taken within 90 days of activation.

Imprint Pilates purveys good health vibrations in the form of Pilates, yoga, acupuncture, massage, and nutrition services. A crowded schedule of instruction takes pupils through classes of up to 75 minutes in length that range from Pilates core dynamics to such chakra-centring yoga sequences as Vinyasa Flow and Ashtanga. Encouraging participants to practice the Pilates or yoga movements at their own pace, the highly trained instructors at Imprint use their experience in fields spanning dance, kinesiology, and physical therapy to grant students the kind of detailed, individualized instruction possible only within a black hole or smaller class sizes.

Spanning multiple floors, Imprint's tranquil, sunlight-drenched facilities boast modern Pilates equipment and spacious yoga areas. Students who don't have their own yoga mat may rent a Manduka for free from the studio. Ever favouring punctuality, the team at Imprint recommend that students arrive around 15 minutes before class, as latecomers are sometimes asked to go outside and clap erasers while in warrior pose.
