I regularly listen to, and heed the advice of: Dr. Peter Attia, Dr. Andrew Huberman, and Dr. Jordan Peterson. I find their viewpoints backed by intelligent thought, scientific research, and actionable material.
I was excited to see Dr. Attia on Jordan Peterson's podcast discussing fitness, nutrition, longevity, and other related topics. The following brief clip gives some amazing information pertaining to the benefits of exercise and what a well thought out program looks like. If you watch one YouTube video today, I hope it's this one - you will not regret it!
