Available basically wherever podcasts are.

He has good variety of guests, athletes, celebrities, scientists, authors, hunters, outdoorsmen, adventurers, etc. If you like ufc he has episodes dedicated to just that.

Episodes can be hit or miss but I really like them for when I am exercises as I don't need to focus too hard to get it like I would with a history or educational podcast. It's conversational so easy to follow and dip in and out.
