The duo's recent pilgrimage to Texas ended with a trip to the state-of-the-art Texas Tech University body composition lab led by Dr. Grant Tinsley. Eric and Omar went through a battery of body composition assessments and had their RMR tested there, and Eric's second epic duel with the Bod Pod went down. This duel resulted in only partial redemption for Eric, and we also learned just how "headstrong" Omar truly is. In this episode Grant joins Iron Culture to discuss the findings of the trip and all the nuances of body composition testing to help us understand the sometimes non-intuitive results the team got, and more broadly the pros, cons, strengths and weaknesses of the various body composition tests that are available.
