My guest is Marc Altheim is a yoga instructor and owner of a Yoga studio, Know Yoga Know Bliss, in Manhasset on Long Island, NY. He was formerly a real estate developer (co-founder of Atlantic Development Group) and founder of Beach Tennis USA, a company that introduced the sport of beach tennis to the USA and Canada. At Know Yoga Know Bliss all students, beginners and experts, are welcome, The studio is zen-like and well appointed. Marc specializes in teaching a Men's-only yoga class in order to attract guys who would otherwise not be amenable to trying yoga. The class emphasizes checking egos at the door and teaches the guys to accept the architecture and pliability (or non-pliability!) of their bodies. The class has been a resounding success as the men feel more secure in this environment.
