Flex Diet Podcast

Welcome back to the Flex Diet Podcast! I’m your host, Dr. Mike T. Nelson, and today’s episode is a special rebroadcast of a conversation I had on the Barbell Shrugged podcast with Anders Varner. We dive deep into what I call the Flexible Meathead Cardio Approach — a method designed specifically for strength athletes and lifters who know they need cardio but don’t want it to kill their gains.In this episode, I break down how to build a cardio plan that enhances, not competes with, your strength and performance goals. We cover why aerobic conditioning is a secret weapon for recovery, how it helps you train harder over time, and how to structure your week for maximum benefit.We also get into the weeds on VO2 max testing, different cardio modalities (and when to use them), and how to leverage health data from wearables like the Oura Ring for smarter training decisions. If you’re a lifter who wants to be strong and fit without living on a treadmill, this one’s for you.Sponsors:Tecton Life Ketone drink! https://tectonlife.com/ DRMIKE to save 20%LMNT electrolyte drink mix: miketnelsonlmnt.comFexible Meathead Cardio Level 1: Sign-up hereAvailable now:Grab a copy of the Triphasic Training II book I co-wrote with Cal Deitz here.Episode Chapters:00:35 Flexible Meathead Cardio Approach00:55 Enrollment Details for the Cardio Course01:45 Podcast Collaboration and Disclosure02:08 Introduction to the Barbell Shrugged Episode02:12 Cardio for Strength Training Enthusiasts05:28 Benefits of Aerobic Training for Lifters09:51 Personal Experience and Data Insights22:58 Structuring Cardio for Muscle-Bound Athletes27:49 Interval Training and Output Management29:03 Recovery Strategies for Intervals31:08 High-Intensity Intervals vs. Long Runs33:41 Understanding VO2 Max Testing39:04 VO2 Max Standards and Goals45:32 Structuring a Balanced Training Week47:46 The Importance of Consistent Cardio49:36 Conclusion and Where to Find More InformationFlex Diet Podcast Episodes You May Enjoy:Episode 287: Insights and Innovations in HRV and Aerobic Training with Coach Joel JamiesonEpisode 138: Why Everyone Benefits from Aerobic Training – Even MeatheadsGet In Touch with Dr Mike:Instagram: DrmiketnelsonYouTube: @flexdietcertEmail: Miketnelson.com/contact-us

Welcome back to the Flex Diet Podcast! I’m your host, Dr. Mike T. Nelson, and in this episode, I sit down with my good friend Dr. Kenneth Jay, a PhD in Physiology and Biomechanics, coach to Olympic-level athletes, and creator of the Row Forge app.We go deep on all things cardiovascular performance, especially how to improve aerobic capacity without losing your hard-earned strength.
