    Peptides: Worth the Hype?

    Peptides are everywhere right now — in fitness ads, longevity podcasts, and your gym buddy's supplement stack. But what actually are they, and do they work? In this episode, Coach Chris Cooper breaks down the science behind peptides: what they are (short chains of amino acids your body already makes), why they've exploded in popularity, and whether the fitness-focused ones are actually worth your money. The short version: pharmaceutical peptides like Ozempic are the real deal — rigorously tested, FDA-approved, and backed by large clinical trials. The peptide supplements being sold online for fat loss, muscle growth, injury healing, and anti-aging? Most of them exist almost entirely in the animal research stage. There are no established human doses, quality control is unknown, and several popular ones are classified by the FDA and World Anti-Doping Agency as unapproved substances. Chris explains why the hype isn't accidental — the supplement industry runs on novelty, and the success of GLP-1 medications created a massive halo effect for the entire peptide category. Influencers and media coverage did the rest. You'll also learn three practical ways to protect your wallet: demand human clinical trial data before buying any supplement, seek out actual medical professionals for injury recovery, and put your money where 30+ years of human research already points. The boring answers — creatine, protein, sleep, progressive training — are still the right ones. Ready to cut through the noise? Visit catalystgym.com.

    Why Stress Is Making You Fat (And What to Do About It)

    You're eating reasonably well. You're trying to move more. But the weight keeps showing up around your middle and won't budge. It might not be your diet. It might be your cortisol. In this episode, Coach Chris breaks down exactly what chronic stress does to your body — and why it works directly against every health goal you have. Cortisol is your primary stress hormone. In short bursts it's essential. But when stress is chronic — shift work, financial pressure, a Northern Ontario winter that never seems to end — cortisol stays elevated all day. And that changes everything. Elevated cortisol encourages your body to store fat specifically in your abdomen — the most dangerous location, linked to heart disease, type 2 diabetes, and metabolic syndrome. It can even trigger the creation of new fat cells in adults. It hijacks your brain's reward pathways, driving cravings for high-fat, sugary comfort foods. It disrupts your sleep, which elevates cortisol further and throws your hunger hormones completely off balance. And over time, it breaks down muscle — slowing your metabolism and making fat loss even harder. This isn't a willpower problem. It's biology. And the interventions are specific. You'll learn why moderate exercise is one of the most powerful cortisol regulators available, why sleep is a non-negotiable health intervention, and how to build one stress-management habit that isn't food. You can't fix a cortisol problem with willpower. But you can fix it with the right habits. Start at catalystgym.com/free-intro.

    What is Hybrid Racing?

    Hybrid racing is exploding in popularity—and for good reason. It's accessible, challenging, and gives you a clear goal to train toward. In this episode, Chris breaks down what hybrid racing actually is, starting with Hyrox: the fitness race that combines running with functional workout stations like rowing, sled pushes, burpees, and wall balls. Hyrox events sell out in minutes, which is why gyms worldwide now host "sims" to give athletes a taste of competition without the travel and expense. But Hyrox isn't the only option. Hybrid racing includes triathlons, duathlons, biathlons, Spartan races, and even some CrossFit workouts like Murph. The common thread? They all mix endurance with strength or power in one continuous event. Why is hybrid racing so appealing? The barrier to entry is low. Unlike a CrossFit competition with complex barbell lifts, hybrid races use simple movements you can learn in a single session. But the ceiling is high—elite athletes find endless room for improvement through better pacing, conditioning, and raw output. Chris also answers a key question: is CrossFit hybrid racing? Not quite. While some CrossFit workouts fit the mold, full competitions include max lifts and gymnastics skills that create a higher technical barrier. This summer, Catalyst is programming hybrid racing workouts every Saturday. If you're ready to try a real event, check out the Copper Bay Triathlon and Duathlon in Bruce Mines, Ontario. Whether you're chasing a podium or just looking for a training goal, hybrid racing gives you something to work toward.
