When is exercise too much of a good thing?  When is it time to push ourselves?  How do we know it's safe to continue?  When should we stop? 

Dr. Abhishek Seth discusses guidelines to help answer these questions.  Dr. Seth studied at the University of Toronto, did his residency at Drexel University College of Medicine, and received his M.D. from the Ross University School of Medicine.  Since June, Dr. Seth has been a Medical Fellow in Geriatric Medicine at the Irving Sherwood Wright Center of New York-Presbyterian Hospital/Weill Cornell Medical Center.
