Julia is AEA and Cooper Institute certified and annually gets recertified and re-motivated by attending FitnessFest Conferences. “My water workouts offer all the benefits of land-based exercise without the stress on joints caused by gravity. Jogging and jumping can be performed comfortably in water because participants are supported by buoyancy.  Non-swimmers OK too”! Julia’s other job involves pet sitting!
