In this episode of the Flex Diet Podcast, I’m joined by the always-interesting Levi Earl, who's tuning in all the way from Finland, to nerd out on all things aerobic training, grip strength, and how to make your meathead conditioning actually work for you, not against you.We dive into why strength athletes need better aerobic systems (no, it’s not just for skinny endurance types), how mountain training builds freakish capacity, and why grip training is way more than just farmer’s carries until your soul leaves your body.We also delve into sport-specific gems, such as what wrestlers, hockey players, and other power athletes can glean from these methods to enhance their performance without tiring out.Whether you’re a high-level athlete or want to stop sucking wind between sets, you’ll walk away with some highly usable intel.Give it a listen—grab your notebook, and consider bringing a pulse oximeter if you're feeling particularly curious.Sponsors:Tecton Life Ketone drink! https://tectonlife.com/ DRMIKE to save 20%LMNT electrolyte drink mix: miketnelsonlmnt.comAvailable now:Grab a copy of the Triphasic Training II book I co-wrote with Cal Deitz here.Episode Chapters:05:22 Conversation with Levi Earl Begins05:30 Grip Training Insights and Techniques08:51 Aerobic System Benefits for Grip Athletes10:12 Training Methods and Recovery11:53 Grip Training Tools and Techniques21:34 Aerobic Conditioning for Lifters32:01 Maintaining Aerobic Base During Sports Season39:30 The College System and Athlete Development39:37 Isometric Training in Greco Style Wrestling40:01 Mountain Training: Benefits and Challenges41:12 Altitude Training: Science and Practical Insights43:53 Mental and Physical Benefits of Mountain Training47:26 High Altitude Training for Different Sports52:38 Hypoxic Training and Its Applications54:53 Weight Cutting and Altitude Training01:01:38 Aerobic Training and Cognitive Benefits01:10:00 Conclusion and Final ThoughtsFlex Diet Podcast Episodes You May Enjoy:Episode 177: Training Principles from Gonzo Grip Strength with Adam Glass and Dr Mike T Nelson - https://youtu.be/u7659KqTKWQ Episode 264: Finding Your Aerobic Sweet Spot for Peak Health with Dr Phil Batterson - https://youtu.be/AbX9VyB8DscConnect with Levi:Instagram: https://www.instagram.com/leviearl/Website: https://www.leviearl.com/About Levi:Levi Earl is an Olympic-level Strength & Performance Coach based in Finland.

Episode 327: Flexible Meathead Cardio: Barbell Shrugged Rebroadcast with Dr Mike T Nelson
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
