What Your Doctor May Not Tell You About Heart Disease

Most interesting passage, to me at least, was where Dr. Houston suggests exercise is not about burning calories. That is simply a side effect. The real story is about hormones and how different exercises affect these hormones. Short answer: running for an hour is bad and lifting weights, particularly full body participation is very good. Further, in order to burn fat, you must build muscle. Can't build muscle (and in fact you burn muscle) doing long, steady cardio.
