That's a good question. It's also a tough question. Here's a small part of the answer.
As we age, production of Human Growth Hormone falls off. HGH is an unfortunate name, because it's relevant to grown-ups, as well as growing children. HGH promotes lean muscle mass and fat loss. How can we put this understanding to use?
Serious strength training can trigger Growth Hormone release. I choose to do upper leg work.
I have been moderately overweight -- but within the healthful range -- for most of my adult life. Now Iam slightly leaner than I was 30 years ago. And by some measures, I'm a senior citizen.
Yes. Regular, moderate aerobic exercise is healthful. But in terms of Growth Hormone release, it does not even begin to cut the mustard.
