Cardiac trouble? Hospital-based exercise teaches you safe limits

"Looking for a place to exercise without the loud music and the skimpy outfits? Inquire at your local hospital about a cardiac rehab program, especially if you have had a heart attack or have undergone bypass surgery, valve surgery, or angioplasty. Medicare (USA) and most other insurance companies cover the expenses of cardiac rehabilitation for people who have recently undergone any of these procedures" - Examiner.com
