Aubrey Marcus owns Onnit. I learned about Aubrey and Onnit via the Joe Rogan podcast. Marcus presents a solid program of mind-body-spirit wellness practices. All very simple. Not sure there was a whole lot of new info for me but I like how it is packaged up. Very simple kettlebell and stretching movements can be found in the book. It would also be helpful if you are trying to improve on a specific area. Got to that chapter, digest it and start applying.

I am continually trying to improve my health. Start with Andrew Weil and then pick up Mark Sisson's book. He really He really does a great job of stripping down and simplifying what you should be doing for nutrition and exercise.

Tim Ferriss' book on nutrition and exercise. He is interested in human optimization. I am someone that has been on a multi-year mission to improve my health. 4HB has played a role. This book introduced me to the concept of the "cheat day." Eat the low to no-carb plan he recommends but then one day per week, gorge yourself on bad stuff. All in an effort to keep your metabolism off balance.
