    Why Running for Weight Loss Backfires... Fuelling Hacks, RED-S & Training Smarter with Sophie (@runfreephysio)

    S3 EP6 – Why Running for Weight Loss Backfires... Fuelling Hacks, RED-S & Training Smarter with Sophie (@runfreephysio) In this episode, we’re joined by running-focused physiotherapist Sophie (@runfreephysio) to break down the science behind fuelling, recovery, and injury prevention for fitness lovers. With more people signing up for marathons, ultramarathons, HYROX and endurance races, many athletes fall into the trap of thinking that getting lighter, eating less, or pushing through fatigue will improve performance. But in reality, chronic under-fuelling and poor recovery habits are some of the biggest drivers of injuries and progress plateaus. Drawing from her experience as a physio, Sophie explains the patterns she sees most often, from athletes dieting during marathon prep, to the impact of low energy availability and RED-S (Relative Energy Deficiency in Sport) on performance, as well as short and long-term health. We also unpack the science of training adaptation, the importance of carbohydrates for endurance performance, and whether common claims like “running ruins your knees” or “running causes arthritis” are actually true. Whether you’re training for a marathon, half marathon, ultramarathon, HYROX, or simply trying to make real progress in the gym, this episode will help you better understand how to fuel properly, recover effectively, and avoid common training traps. In this episode, we cover: *Why running a marathon or ultramarathon should NOT be used as a weight-loss strategy *A physio's take on the most common mistakes made by athletes *What is RED-S? The dark side of underfuelling... *Adapting your fuelling and recovery strategy to overcome plateaus *Active Recovery vs True Recovery *You should STOP avoiding carbs *Importance of energy balance for endurance *Debunking myths like “running ruins your knees” or causes arthritis This episode is a reminder that better performance does NOT come from eating less, shrinking yourself or training to exhaustion, it comes from fuelling properly, recovering well, and training intelligently. When you work WITH your body, rather than AGAINST it by providing it with enough energy and training smart, you build strength, resilience, and long-term performance. NOTE: At the time of recording, Sophie’s social media handle was different. Her current handle is @runfreephysio 🎧 New episodes every Tuesday! ⭐ Follow the podcast & leave a 5-star rating, it helps us grow the community.

    How to Get Jacked and Actually Perform with Abbie Dennison

    S3 EP5 – How to Get Jacked and Actually Perform with Abbie Dennison In this episode, we’re joined by hybrid athlete and creator Abbie Dennison to break down the reality of training for performance, aesthetics, and longevity, all at once. If anyone has cracked the code to looking and feeling strong, it's Abbie. We unpack what truly matters when it comes to building strength and endurance without breaking your body. From beginner advice and smarter training structure, to marathon fuelling, ultra prep and fully committing to HYROX, this is THE conversation for girls who want to do it all. We also dive into Abbie’s journey into content creation, how she built her platform in the hybrid space, and what it’s really like balancing aesthetics with elite-level performance. In this episode, we cover: *How to train hybrid as a woman *Building strength and endurance without constant burnout *The importance of your recovery habits for injury prevention *Fuelling properly for marathon training (before, during and after long runs) *What you should know before signing up for an ultra-marathon *Smart training plans for Hyrox *Performance vs aesthetics, can you genuinely have both? *How Abbie built her platform as a hybrid fitness creator This episode is a reminder that you don’t have to choose between being strong, fast, aesthetic, and ambitious. Performance isn’t about shrinking yourself and it requires dedication. It involves fuelling properly, training intelligently, and committing fully to your goals. The more intentional your training becomes, the more confident you feel in your body. 🎧 New episodes every Tuesday ⭐ Follow the podcast & leave a 5-star rating, it helps us grow the community.

    The Science of Women's Health: Menstrual Cycles, Fuelling & the TRUTH About Weight Loss Drugs with Dr Mimi

    S3 EP4 – The Science of Running with Dr Mimi Is being “built for running” genetic? Do carbon plate shoes really make you faster? What is so great about beetroot juice? And how much does your menstrual cycle impact performance? In this episode, we’re joined by a doctor and runner Dr Mimi to break down the science behind performance, recovery, and women’s health. We don't gatekeep here. We unpack what truly matters when it comes to getting stronger and running faster whilst avoiding injury. From fuelling properly and prioritising sleep, to understanding how contraception and hormonal fluctuations affect training, this is THE conversation for active woman. We also dive into the cultural side of performance, including the rise of Ozempic use, body image pressures and the dark side of running too many races. In this episode, we cover: * Does genetics really determine if you’re “good” at running? * The role of nutrition in performance and recovery * Why sleep is your most underrated performance tool * Why fuelling enough is non-negotiable for strength and endurance * Fun performance facts (beetroot juice, sunglasses, and more) * The truth about carbon plate running shoes * Women’s health: contraception, hormonal fluctuations & training * Ozempic, weight loss culture & body image in sport This episode is a reminder that performance isn’t about shrinking yourself, it’s about supporting your body properly and showing it the appreciation it deserves. The more you understand your physiology, the more empowered your training becomes. NOTE: Dr Mimi does say the majority of runners sustain an injury during marathon training - the statistics are actually closer 33- 50%.  🎧 New episodes every Tuesday ⭐ Follow the podcast & leave a 5-star rating — it helps us grow the community.
