Muscle Growth Explained

 What actually makes muscle grow? In this episode, we break down the science of hypertrophy, starting with mechanical tension as the primary driver and how it activates the mTOR pathway to trigger muscle protein synthesis. You’ll learn what makes tension effective: training close to failure, doing 10 to 20 sets per muscle group per week, applying progressive overload, and training through a lengthened range of motion. We also look at secondary factors like metabolic stress (the pump), muscle damage and soreness, and post-workout hormone spikes, and separate what matters from what’s overhyped. Finally, we cover the recovery side of the equation: getting at least 1 gram of protein per pound of bodyweight (or the amount that fits your goals), eating in a small calorie surplus, prioritizing sleep, and spreading your training volume across the week to re-trigger protein synthesis more often. Whether you’re a beginner or an experienced lifter, this is your science-based roadmap to building muscle. Connect with Ragnar — Join the Wolf-Pack💪 Apply for Coaching:https://primalfitness.fillout.com/Application/📲 Instagram:https://www.instagram.com/thebeastwithin9/👥 Facebook:https://www.facebook.com/profile.php?id=100085074067890▶️ YouTube Channel:https://www.youtube.com/channel/UCw0HLq3TZVkt3VQpyq7kwegThis isn’t fitness fluff.

So you cut your calories, you dragged yourself through the workouts, and for the first few weeks the scale moved and you felt like you finally had it figured out. And then it stopped. Same food, same training, same discipline, and nothing. And you started asking yourself whether something is wrong with you, whether your metabolism is just shot at this age, whether you’re one of those guys who can’t lose it no matter what. You’re not. Your body is doing exactly what it was built to do.In this episode I break down metabolic adaptation, which is your body’s survival response to a sustained calorie deficit. When you diet long enough, your body starts burning fewer calories than the math says it should. You move less without noticing it, your daily fidgeting and walking drops off, and your body gets more efficient with every calorie you give it. That’s not a broken metabolism. That’s a body that thinks it’s starving and is protecting you from dying.Connect with Ragnar — Join the Wolf-Pack💪 Apply for Coaching:https://primalfitness.fillout.com/Application/📲 Instagram:https://www.instagram.com/thebeastwithin9/👥 Facebook:https://www.facebook.com/profile.php?id=100085074067890▶️ YouTube Channel:https://www.youtube.com/channel/UCw0HLq3TZVkt3VQpyq7kwegThis isn’t fitness fluff.

Late Night Snacking Isn't a Willpower Problem — It's a Biology ProblemYou're not weak. You're not lazy. You're not "bad at discipline." If you're raiding the kitchen at 10PM every night, your body is sending you a signal — and most people are misreading it completely.In this episode I break down the three biological drivers behind late night snacking that nobody talks about:1. Low Protein Intake Is Rewiring Your Brain to Crave FoodYour body runs on the protein leverage hypothesis — when you're under-fed on protein during the day, your brain doesn't just get hungry, it specifically drives you toward food-seeking behavior until the deficit is corrected. A meta-analysis of 49 randomized controlled trials (2,740 participants) confirmed protein actively suppresses ghrelin (the hunger hormone) while spiking GLP-1 and CCK (the fullness hormones) — meaning if you're light on protein by dinner, you are neurochemically primed to snack at night. This isn't a discipline gap. It's math your hormones are doing without you.2. Dehydration Is Getting Misread as HungerYour hypothalamus regulates both hunger and thirst — and when you're even mildly dehydrated, those signals cross wires. The result: you feel "hungry" at 9PM when your body actually needs water. I'll walk through why this mix-up happens and how to tell the difference before you open the fridge.3. Bad Nighttime Habits Are Training the Behavior Into a LoopSnacking at night isn't random — it's a conditioned response built through repetition, environment, and routine. I break down exactly how that loop forms and, more importantly, how to break it.This is the difference between white-knuckling your way through cravings and actually fixing the system driving them. Listen to this once and you'll never look at your 10PM fridge trip the same way again.🐺 New episodes of Growth Through Adversity every week.

Your body doesn't grow because you showed up. It grows because you gave it a reason to change. In this episode of Growth Through Adversity, Ragnar breaks down the real mechanism behind progressive overload — the science of mechanotransduction and supercompensation — and the exact double progression framework used to build strength week over week without guessing. Then: the advanced method for when double progression stops working — rest-pause training, backed by controlled research on strength and hypertrophy outcomes.If you've hit a wall in the gym and don't know why, this episode is the missing piece.TIMESTAMPS0:00 — Why most plateaus have nothing to do with genetics0:45 — What progressive overload actually means (SAID Principle)2:00 — Mechanotransduction: how mechanical tension becomes a growth signal3:30 — Supercompensation: why recovery is where adaptation happens5:00 — Double progression: the base framework for building strength7:00 — When double progression stalls (the wall every advanced lifter hits)7:45 — Rest-pause training: the advanced method, and what the research shows9:30 — Recap + what's nextConnect with Ragnar — Join the Wolf-Pack💪 Apply for Coaching:https://primalfitness.fillout.com/Application/📲 Instagram:https://www.instagram.com/thebeastwithin9/👥 Facebook:https://www.facebook.com/profile.php?id=100085074067890▶️ YouTube Channel:https://www.youtube.com/channel/UCw0HLq3TZVkt3VQpyq7kwegThis isn’t fitness fluff.

Motivation is not a strategy — it's a feeling. And if you're building your fitness, your performance, or your life around a feeling, you're already losing.In this episode of Growth Through Adversity, Ragnar breaks down the neuroscience behind why motivation collapses — and the discipline framework that actually keeps high-performing men executing when life gets heavy, the scale stops moving, and work stress spikes.This episode covers:Why motivation is a dopamine-driven emotion — not a character traitThe science of why progress slows the more advanced you become (and why that's actually good news)How to fall in love with the process instead of the destinationThe identity-based discipline system used by elite athletes and performersPractical tools to stay consistent when you don't feel like itReferenced Research:Mohebi et al.

80% of adults will deal with significant back pain — and most of them will be told the same thing: rest, avoid movement, manage it. That advice has failed millions of people.In this episode, I'm pulling back the curtain on how I personally rebuilt my back after a jiu jitsu injury at 24 left me in debilitating pain for 5 years — and how I turned that into a system that's now been run through 300+ clients, including over 200 over the age of 50 and over 100 with active back pathologies.Clients like Jamie, who came in unable to train at all — and 6 months later had minimal back pain. Or Alex, who suffered from chronic sciatica for years before running our program. Or Omar. The pattern repeats because the system works.In this episode:Why rest and avoidance make your back MORE fragile, not lessThe 5 pillars of our back rehabilitation and performance systemCore stiffening vs. core strengthening — why the distinction mattersHow to read pain as data and adjust your training intelligentlyWhy building your glutes and posterior chain may be the most underrated back fixWhat the research actually says about spinal loading and disc healthThis is not physical therapy. This is performance-driven rehabilitation for people who refuse to let pain run their lives.Ready to apply this to your situation?

Most guys think rest means doing nothing. That's leaving gains on the table. Active recovery accelerates muscle repair, clears metabolic waste, and keeps your nervous system dialed in — without eating into your next session. Work smarter between sessions.Connect with Ragnar — Join the Wolf-Pack💪 Apply for Coaching:https://primalfitness.fillout.com/Application/📲 Instagram:https://www.instagram.com/thebeastwithin9/👥 Facebook:https://www.facebook.com/profile.php?id=100085074067890▶️ YouTube Channel:https://www.youtube.com/channel/UCw0HLq3TZVkt3VQpyq7kwegThis isn’t fitness fluff.
