A couple of great fitness blogs
Two of my favourite fitness blogs are http://www.bengreenfieldfitness.com/ and https://www.foundmyfitness.com/
Ben is an ex-bodybuilder & an ironman style multi athlete. Rhonda Patrick is a nerdy scientist into fitness.
Both of them invest the focus of time & energy into their blogs as the cornerstone of business operations so they are up to date with podcasts, articles etc.
Rhonda has a big pile of videos and some awesome info. Ben does more podcasts. Now if these two got together & released an info product it would be dynamite.
