Episode 332: Muscles, Mind, and Metrics: Biomechanics with Dr. Doug Goldstein

In this episode of the Flex Diet Podcast, I sit down with Dr. Doug Goldstein for a deep dive into biomechanics, performance, and recovery. We get into the weeds on muscle performance, body comp, and how to reduce injury risk—stuff that matters whether you're an elite athlete or just trying to move and feel better.We also explore some cutting-edge tools like Springbok Analytics and dive into how intramuscular dry needling can change muscle properties to enhance performance. Plus, we break down contralateral adaptations, mental performance strategies, and smart approaches to overload.Lots of real-world applications and case studies in this one — don’t miss it.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:06:09 Dr. Doug's Journey in Physical Therapy07:05 Case Study: Demaryius Thomas12:28 The Role of Mental and Mechanical Components in Performance22:30 Exploring Springbok Analytics43:35 Understanding Tommy John and Elbow Injuries43:47 The Role of Lower Body Mechanics in Pitching45:06 The Importance of Hip Mobility and Pelvic Control47:54 Exploring Intramuscular Dry Needling48:58 The Impact of Dry Needling on Muscle Function50:26 Reevaluating Muscle Anatomy and Function54:05 The Role of Visual Data in Biomechanics01:02:11 Collaborative Approaches in Biomechanics01:05:02 The Importance of Asking Questions and Sharing Knowledge01:17:58 Conclusion and Final Thoughts Flex Diet Podcast Episodes You May Enjoy:Episode 311: Maximizing Athletic Performance with Neurology: Insights from Dr. Dylan Seeley: https://miketnelson.com/episode-311-maximizing-athletic-performance-with-neurology-insights-from-dr-dylan-seeley/ Episode 296: Enhancing Athletic Performance with Dr. Dani LaMartina: https://miketnelson.com/episode-296-enhancing-athletic-performance-with-dr-dani-lamartina/Connect with Doug:Instagram: https://www.instagram.com/springboktech/Website: https://www.springbokanalytics.comGet In Touch with Dr Mike:Instagram: DrmiketnelsonYouTube: @flexdietcertEmail: Miketnelson.com/contact-us

In this episode of the Flex Diet Podcast, I’m diving into the nitty-gritty of blood work and why it matters for your health, performance, and longevity, especially if you're an athlete, bodybuilder, or serious about your training.Fresh off the ISSN (International Society of Sports Nutrition) conference, I’m joined by Michael Warner, a sharp coach at Marek Health and the owner of Set the Standard. Together, we unpack some of the most important markers in blood work, how training and nutrition can influence your results, and how to actually interpret those lab numbers in the real world.We also discuss the importance of hydration, the context behind the numbers, and why proactive health monitoring should be an integral part of every performance plan. And yes, we touch on the impact of PEDs (performance-enhancing drugs) and what they can do to your blood markers.Whether you’re optimizing for gains or longevity, this is a must-listen for anyone who wants to truly understand what’s going on under the hood.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:00:16 Recap of the ISSN Meeting00:40 Guest Introduction: Michael Warner00:59 Importance of Blood Work for Health and Performance01:28 Personal Experience with Blood Work02:15 Basic Blood Tests and Their Accessibility03:19 Interpreting Blood Work Results03:37 Vitamin D and Lifestyle Factors04:08 Focus on Exogenous Compounds04:31 Sponsor Shoutouts06:48 Interview with Michael Warner Begins08:04 Blood Work in Physique Athletes08:57 Variability in Blood Work Results13:21 Blood Pressure and Easy Checks15:01 Proactive Health Monitoring15:48 Whack-a-Mole Lab Work19:11 Preparing for Lab Work26:33 Frequency of Blood Work29:45 Enhanced Athletes and Blood Work33:08 Risks and Rewards of Enhancement35:57 TRT and Personal Experiences38:18 Fertility and Performance Enhancing Drugs39:03 Introduction to Fertility Clinics and At-Home Sperm Tests40:27 Misconceptions About Testosterone and Fertility41:26 Essential Blood Work for Health and Performance44:26 Advanced Markers and Kidney Function46:25 Importance of Iron Panels and Sex Hormones50:16 Thyroid Panels and Additional Health Markers54:56 Merrick Health and Telemedicine Services01:04:22 Conclusion and Final Thoughts Flex Diet Podcast Episodes You May Enjoy:Episode 201: Coaching clients to look and feel their best: An interview with Lacey Dunn, RDEpisode 144: Peptides – Bleeding Edge Performance, Muscle, and Recovery with Dr. Andy Galpin & Dr. Ryan GreeneConnect with Michael:Instagram: https://www.instagram.com/mawsome_Website: https://marekhealth.com/Get 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 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

In this episode of the Flex Diet Podcast, I sit down with Dr. James Fadiman and Jordan Gruber to talk all things microdosing—what it is, what it isn’t, and why it’s gaining so much traction in health, performance and even mental clarity.We dig into their new book, Microdosing for Healing, Health, and Enhanced Performance, and cover everything from the history of psychedelics to the latest research and how people are using tiny doses of these compounds to potentially improve cognitive function, mood and physical performance.We also talk about personal experience—what they’ve seen, what they’ve felt, and what they’ve learned along the way. Of course, none of this is medical advice. These substances still live in legal gray zones depending on where you are, so proceed with caution and do your homework.If you’re curious about the science and the real-world implications of microdosing, this episode is a must-listen.
