The Real Hypertrophy Secret: Why Effort Matters More Than Rep Range
Muscle growth is not mainly about finding the perfect rep range—it’s about getting close enough to failure, with the right technique, at the right dose.In this episode of the Fitomics Podcast, Coach Aaron Feld sits down with Dr. Cody Haun, PhD physiologist and CEO, for an unplanned deep dive into muscle hypertrophy, training intensity, and why the same workout can produce completely different results for different people.They begin with one of the most common questions in strength training: What rep range should you use to build muscle?From there, they explore why proximity to failure may matter more than chasing a “magic” rep range, how technical failure differs from total mechanical failure, and why most lifters underestimate how many reps they actually have left.The conversation also explores why understanding physiology matters for coaches and clients. You may know what to do without knowing why it works—but when your progress stalls, understanding the “why” can help identify the right lever to pull.If you’ve ever thought, “I’ve tried everything and nothing works,” this episode offers a different perspective: the solution may not be adding more to your routine. It may be removing what is getting in your way.For more information, visit fitomics.com or fitomics.com/interest.Fitomics Resources:Instagram: • https://instagram.com/fitomicshq• https://www.instagram.com/drcodyhaun/• https://www.instagram.com/coachfeld/Facebook: https://facebook.com/fitomicsWebsite: https://fitomics.comResearch Labs Insider: https://fitomicslabs.comSupplement Shop: https://us.fullscript.com/welcome/fitomics/ #MuscleGrowth #Hypertrophy #StrengthTraining #ExerciseScience #FitnessPodcast

Boost Energy: Improve VO2 Max & Fat Oxidation #fitness #healthtips #vo2max
Most people get fat-loss cardio backwards. The real answer isn’t simply “go harder” or “stay in the fat-burning zone”—it’s understanding how your body uses oxygen, fat, and glucose at different intensities. Dr. Cody Haun and Coach Aaron Feld break down the science behind VO2 max, fat max, and why the most effective training zone differs from person to person. If you’ve ever wondered why Zone 2 is so popular, why higher intensity can still burn more fat overall, or why you feel exhausted even when you’re “doing everything right,” this conversation connects the dots.You’ll learn: • Why the percentage of fat burned isn’t the same as the total amount of fat burned• How VO2 max testing reveals what your body is doing during exercise• Where fat max often occurs—and why it can change as you train• How Zone 2 supports recovery, endurance, and metabolic efficiency• Why improving aerobic capacity can make everyday activities feel easier• How better fat oxidation may help preserve glucose for higher-demand workThe conversation also explores the relationship between aerobic conditioning, energy availability, recovery, and performance—from hard training sessions to mental focus and daily life.If you want a smarter way to train, improve your energy, burn fat, and build endurance, this episode offers a practical, science-informed roadmap.Fitomics Resources:Instagram: • / fitomicshq (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljR09nQkthbWJhSnBqMjlob01uSDhtYnxBTl9pYzRjR0xFTjA4NktYZWxIamUxbG52dG5XQV9oNFRqVlltS2s4dmZ0NGFMd2VaSUkzdG15eloySHFJY3hENC1JaHR1VmU5bTZfZWlpLUJBRWNmT0hUdW5sTW1INllSbnct&q=https%3A%2F%2Finstagram.com%2Ffitomicshq&v=uXV0vKozr4s)• / drcodyhaun (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljR2R6WkNPYnJpZjR0OWNIUWR1aDdPcXxBTl9pYzRlVThEbWRYQmlyWDBoeHJsLWlZRVprREFqeEZNLUl1Qjg5THlQal9mdWJydlo0aXZId3FaaEFMQzFvZzkyOFh4YTlTenk0dTVMbHM3eElWN04zY3NPRVRveUFqN19h&q=https%3A%2F%2Fwww.instagram.com%2Fdrcodyhaun%2F&v=uXV0vKozr4s)• / coachfeld (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljSDIyRDVaQUIydDdaaGdGNG5FWWdjR3xBTl9pYzRkZGl3aElBeENyaXlObmpKMHhXcnpZUXQ1YjVMYWNNdWhUOXE1MW1URG84STNyVE1GY1BuOUppUmhrcnNwYVQ0Zlp2R1lJOEY5bWFFeWlOVFVOUXRFQ0lVbVBBZzNK&q=https%3A%2F%2Fwww.instagram.com%2Fcoachfeld%2F&v=uXV0vKozr4s)Facebook: / fitomics (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljSFBXNFRuNHFreXVqWldLdm5wVXk1UHxBTl9pYzRkUzYySDhaancxZ2xXTWtZbWVXR3FxcTJTRkNfckZoNkVLdlZYd1A3SUsxT0hwTVVKZVBXWXRoYXRjZ2NuLUhISDlENUp1c2R3eENLNDhuaUQ5NUdPVjBCVjc0eTFq&q=https%3A%2F%2Ffacebook.com%2Ffitomics&v=uXV0vKozr4s)Website: https://fitomics.com (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljRXNuX1oxbC1WaU5wUHBzcVBHRnJjdXxBTl9pYzRjVUUtb2RLUmhUTHI4ZERfOTVrbWR3eFNhUmpmRk9NVWs4N3R3T1o4RW5xVkRyNFRjNno0R0JXS3loY0ExSzBaeDZ6VlhScXhxQ1E4VkZzUFE0Z1ZHUWNGLUlmWnpt&q=https%3A%2F%2Ffitomics.com%2F&v=uXV0vKozr4s)Research Labs Insider: https://fitomicslabs.com (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljRl9remZoV0F5VFZLVHVidnBVbGZhdXxBTl9pYzRjNEJpSExIWGZqbkg4NmU5b2cxUV90SUJObUJFNzFkR0FMRko1QU5ucEV5LXBsY3FpZFVnWlROMnY1dWZmblVYYTQySl9hVThDMURSUGVsMlJGeXUwb0ZMNGh2ZmRO&q=https%3A%2F%2Ffitomicslabs.com%2F&v=uXV0vKozr4s)#VO2Max (https://www.youtube.com/hashtag/vo2max) #Zone2Training (https://www.youtube.com/hashtag/zone2training) #FatOxidation (https://www.youtube.com/hashtag/fatoxidation) #CardioTraining (https://www.youtube.com/hashtag/cardiotraining) #MetabolicHealth (https://www.youtube.com/hashtag/metabolichealth)

Why Eating Less Can Stall Fat Loss and Cost You Muscle
Eating less does not always mean losing more fat. If you are cutting hard, training hard, or stuck in a cycle of low energy, this conversation breaks down why chronic underfueling can quietly affect recovery, hormones, immune function, and even body composition.Coach Aaron Feld and Dr. Cody Haun explore bioenergy availability—what it is, how to calculate it, and why your body has a limit to how much fat it can mobilize before it starts tapping into muscle and other fat-free mass. They also unpack the signs that you may be underfueling before your performance falls apart.In this episode, you’ll discover:Why a severe calorie deficit can backfire on fat lossHow low energy availability can affect mood, recovery, heart rate variability, and blood markersThe role of IGF-1, thyroid hormones, testosterone, and sex hormone-binding globulin in adaptationWhy protein intake and resistance training can dramatically change the type of weight you loseHow the thermic effect of feeding worksWhy protein can provide more metabolic leverage than many people realizeHow to lose body fat without sacrificing the muscle you have builtDr. Haun also explains the rate-limiting nature of fat loss, including the often-misunderstood idea that your body can only safely mobilize so much body fat per day before it has to look elsewhere for energy.If you have ever wondered why “just eat less” can lead to lower energy, weaker workouts, and disappointing results, this episode offers the missing nuance. It’s essential listening for anyone cutting weight, coaching clients, or trying to improve body composition without losing muscle.For more information, visit fitomics.com or fitomics.com/interest.Fitomics Resources:Instagram: • / fitomicshq (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljRXViTmI0c2JEbGdNSzBDMDdoenVPVXxBTl9pYzRmeFJhMUFNQlRYNXJ0RTU1bnBTc2dhTENibmtLa2FwRlRvODRNMjZTdmM1MXRBUTdkRW9PVmtFSE80Z1BvTWVWNUMwOFlnT3lTSXZHd2ZSSVREZUlONzY3MzJVY0Zo&q=https%3A%2F%2Fwww.instagram.com%2Ffitomicshq&v=OfLRIYDKTu4) • / drcodyhaun (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljR2ViSHdvTlJrQVppTzBJY3AwX1JSYXxBTl9pYzRjMGl6bzdIRUo4Y0hkQmNGX3dhZGNxLVZVZFA1YXMzQ1lKRk51ck01cXg4NmYtMElNRzZpd01hcTkyVGNXbnVtSGdUeHRpTlZTMXQ2b0NqdjFpRUszcG5Jb0Y5VlhM&q=https%3A%2F%2Fwww.instagram.com%2Fdrcodyhaun&v=OfLRIYDKTu4) • / coachfeld (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljRzVJeHgwSGhOZjJsaDRfdndMaDhYUHxBTl9pYzRmd1dRTno5S0NfMFhWWnNYS3dxV3R2ZnowelFubEc0OVhmSUdzT2FaeFVqRXVwU0NweUVlQ1VSR1QtdWZJMWltald1Ql96WnBoOUdkMVp2eXkwTkxYSVdNdURMdWo2&q=https%3A%2F%2Fwww.instagram.com%2Fcoachfeld&v=OfLRIYDKTu4) Facebook: / fitomics (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljR3dkYlFIVTE0QlotZzhPb3QyUDJob3xBTl9pYzRjcmd2dFNBTktLZi02S1NzY2pCNmpNUERNN01FSm5uS0tqSzBfd2ozRmx0R0N1Q2lEa0Z5TW95aUgtVU14UDdOQzhORHBGQmM2MzBtT2hHQkRpeUdxUTJWb2g0Q0c5&q=https%3A%2F%2Fwww.facebook.com%2Ffitomics&v=OfLRIYDKTu4)Website: https://fitomics.com (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljSDdRWkR1dDEtdkRjMGg5ejNFOWd0eXxBTl9pYzRmanRhaUNaN3Y4bUJTZzRwTXNKSW9yNHVtUlNzay1xcE9CYnprTHBfeGtfMXlZUWxnMk8ySVNNdkpieXB2SG1zWE4yVWNwT2FvcWNPQ1RJZ3RERkYtOWRFd2JNc2M5&q=https%3A%2F%2Ffitomics.com%2F&v=OfLRIYDKTu4)Research Labs Insider: https://fitomicslabs.com (https://www.youtube.com/redirect?event=video_description&redir_token=QUZZTVljRWZvQmVWb3JhOWlPSS1yVDFheUoxdnxBTl9pYzRkZDhQNTJsczlRWUplMDAxdV8wT2dSTWRBSk0yV2l5ck5MNGJJZjFiZzB1MVVrcHJKckJGTkR0Sy1JZFV6d3B3ZHdFUTZYV3VndW01akZvNTNiRWNxbEtBYWV4T3J0&q=https%3A%2F%2Ffitomicslabs.com%2F&v=OfLRIYDKTu4)Supplement Shop: https://us.fullscript.com/s/fitomics/...

Beyond Full Range of Motion: Exploring Lengthened Partials in Training
Drs. Cody Haun and Daniel Lawson explore the recent study (PMID: 39995432) on lengthened partials following full range of motion training compared to full range of motion alone during a calf raise exercise. The discussion covers the potential mechanisms behind muscle growth, the definitions of failure in training, the study's design and results, and practical applications for trainees and practitioners. Takeaways: Lengthened partials may promote more muscle growth than full range of motion. Mechanical tension is a primary driver for muscle hypertrophy. Understanding momentary failure vs. volitional failure during training. Bayesian statistics provide a different perspective on training effectiveness. The study showed that past failure lengthened partials appeared to result in better hypertrophy outcomes. Untrained populations may limit the generalizability of findings. Drop sets can be an effective and time-efficient training method. Managing fatigue and soreness is essential for effective training. Future research could provide deeper insights into training techniques.-Lengthened partials are a viable option for muscle growth.

Beyond the Double Helix: Gene Enhancers & Exercise
How does exercise influence your body beyond the typical weight loss narrative? In this thought-provoking episode, Dr. Matt Romero—professor of Molecular, Cell, and Developmental Biology at UC Santa Cruz—joins us for a deep dive into the world of gene regulation, tissue-specific expression, and the unsung genetic elements that may hold the key to better health and performance. We explore how exercise affects your genome at the cellular and molecular level, including the role of enhancers, transcription factors, LINE-1 elements, and even cutting-edge gene editing tools like CRISPR-dCas9. From practical implications to theoretical frontiers, this is a nerd-friendly episode for anyone curious about molecular biology, epigenetics, and how movement talks to your DNA.🧬 Topics include: Why only 2% of your genome codes for proteins How enhancers regulate gene expression in a tissue-specific way The surprising health benefits of exercise beyond weight loss-CRISPR, epigenetic modulation, and futuristic therapeutics The connection between gene expression and human evolution How Long Interspersed Nuclear Element-1 (LINE-1), a family of retrotransposons, or "jumping genes," are a significant part of the human genome and may cause genetic variation and potentially contribute to diseases like cancer. 🔧 Audio note: We acknowledge some audio quality issues at a few time points in this episode.

Motor Units, Hypertrophy, and Neuromuscular Research with Dr. Alex Olmos
In this episode, we're joined by Dr. Alex Olmos to discuss motor units, hypertrophy, and neuromuscular research. We first dive into what a motor unit is, how motor units are measured, and the limitations and considerations of measuring and interpreting motor units during resistance training. The second half of our talk in this episode focuses on a 2016 paper from Pope et al. titled 'Action potential amplitude as a noninvasive indicator of motor unit-specific hypertrophy' (PMID: 26936975 (https://pubmed.ncbi.nlm.nih.gov/26936975/)). This study was the first to investigate if longitudinal changes in motor unit action potential size predicted changes in vastus lateralis muscle cross-sectional area (mCSA) using surface electromyography (sEMG).
