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. 00:00 The controversy that the Iron Culture won't stand for 08:03 Welcoming back on the podcast, Dr Grant Tinsley 13:27 Understanding how body composition is estimated by multiple compartment methods 31:20 The applications of bioelectrical impedance for physique sport peaking 37:00 All about DEXA and how it fits into the six-compartment model 57:24 Explaining errors within body composition assessment 1:08:23 How measurements can be affected and the future of body composition testing 1:19:15 How metabolism is measured and metabolic adaptation 1:30:55 Thanking Dr Grant Tinsley and closing out (The BodPod) Website https://granttinsley.com/ Instagram @grant_tinsley_phd https://www.instagram.com/grant_tinsley_phd/ Twitter @GrantTinsleyPhD https://twitter.com/GrantTinsleyPhD ResearchGate https://www.researchgate.net/profile/Grant-Tinsley
