Wow. Good for you. A 4 mile run would almost certainly kill me. I think I'd drop dead after about a mile. Cardio is the one thing I'm really not good on, and I have a minor arrhythmia. About 20 burpees and I feel close to blacking out. I want to improve on it, but very carefully. But it's still been possible to lose a good amount of weight without putting a lot of strain on my heart. Still not at my high school weight, though! I was 130. I've come down from a high of 175 to 155, and have a hard time getting below that.
