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.
