Heart rate Quote by Barry Sears
““Luckily, you don't have to inject growth hormone to burn fat and build muscle. All you have to do is train anaerobically. But you do have to understand that you only begin to exercise anaerobically when you are at levels in excess of 90 percent of your maximum heart rate. This is pretty hard work. It's also why world-class sprinters and swimmers are heavily muscled and at the same time very lean—they train anaerobically.””
