Yoga is a much easier way to exercise both mind and body than testing Einstein’s theory of relativity by racing a beam of light. Avoid a science-related sprain with today’s Groupon to Tri-Yoga Calgary. Choose between the following options:

The instructors at Tri-Yoga Calgary demonstrate muscle-moulding techniques to yogis of all levels in a range of hot and non-heated classes and workshops. Students lengthen limbs in a choice of balmy options, including a “warm” class for beginners and a core class that teams up hot yoga and Pilates to strengthen abdominals, tackle poor posture, and rescue midriffs from oncoming trains. Teachers split Yang/Yin classes into a heated half that hones flexibility and strength and a cooled-down half that fosters calm, centered minds. Meanwhile, Kundalini classes promote self-healing through the balancing of mind, body, and soul. The studio welcomes both drop-ins and those who claim space on the online calendar. Elastic fitness-seekers can stretch out on rented mats and towels ($2) or bring in their own.

Though not included in this Groupon, caregivers can salute suns while their wee ones revel in the toys, TV, and foam mats of Tri-Yoga’s childcare area. Trained volunteers with experience in first aid supervise play and miniature UN summits in a safe space behind the studio’s front desk.
