Brian sits down with Dr. John Jaquish, the Wall Street Journal bestselling author of the book Weight Lifting Is A Waste Of Time, So Is Cardio, And There’s A Better Way To Have The Body You Want! He developed OsteoStrong, a groundbreaking bone density building medical technology, and is now in partnership with Tony Robbins. He is also the inventor of the X3 Bar, which has been proven to develop muscle much faster than conventional weight lifting. Dr. Jaquish’s methods have been used to train the world’s most elite athletes, such as the entire Miami Heat organization, various NFL and NBA players, as well as Olympians.
