In-home and online training sessions are also available, but the lion's share of the business here is individually tailored fitness programs aimed at reaching unique, personal goals for each client. Nutritional counseling and body fat testing are available. Owner Brett Parker, a Northeastern graduate in Biology and Physical Therapy, has years of experience teaching rehabilitation classes in hospitals and studying under famed teacher Arthur Sennott in Japanese Sotai and Shiatsu therapy.
