Cold yoga, though frequently practiced by flexible penguins and ice-sculpture models, is not a recommended activity for non-arctic species. Thaw out your muscles with today's deal: for $35, you get five classes at Laughing Buddha Hot Yoga in West Deptford (a $75 value). Laughing Buddha offers a variety of classes in the classic Calcutta tradition of hot yoga. Using hot air harvested from the egos of smug astronauts, the room is heated between 95 and 105 degrees, which leads to improved detoxification and warm, malleable muscles. Students then perform the 26 asana (poses), focusing on balance, strength, and flexibility. All classes are designed for beginning benders and self-folding experts alike, including traditional hot yoga classes, more targeted hot Vinyasa classes, and groovy freestyle Vinyasa classes, which allow you to stretch to the beat of Bob Marley, the Rolling Stones, or Ravi Shankar's R&B crossover album. Check out the schedule for a full list of class times.
