Beyond the Scale: How Strength Training Protects Your Muscle, Metabolism, and Mind on GLP-1 Medications

Meet Josh Martin: The Fun, Empathetic and Clinically-Skilled Trainer at CGPT At CGPT in Hawthorn, personal trainer Josh Martin brings together clinical expertise, lived experience with injury, and an infectious love of movement to help clients feel stronger, more confident, and genuinely enjoy training again. With a Master’s qualification in Clinical Exercise Physiology and a background in competitive sport, Josh works with a broad range of clients, from those returning from injury to everyday people who simply want to move better and feel healthier. Josh’s philosophy is simple: training should be effective, supportive, and most importantly, something people actually look forward to. From Injury to Purpose-Driven Coaching Josh’s path into personal training was shaped by his own setbacks. As a cricketer, he experienced both a significant back injury and a shoulder reconstruction, which introduced him to high-quality rehabilitation and strength coaching early on. “Working with great trainers during that time showed me how powerful good coaching can be,” Josh explains. “I wanted to give back to the industry that gave me so much, and connect with clients on a more personal, empathetic level.” That experience now underpins everything Josh does at CGPT. He understands what it feels like to be limited by injury, uncertain about your body, and rebuilding confidence one step at a time. Clinical Knowledge, Applied to Real People Josh holds a Master’s degree in Clinical Exercise Physiology, which has given him extensive exposure to clients managing injuries, medical conditions, and complex rehabilitation journeys. At CGPT, he applies that knowledge in a practical, approachable way, supporting a general population clientele, while drawing on his clinical experience to ensure training is safe, progressive, and effective. This balance allows Josh to work confidently with clients who may be returning from injury, managing pain, or simply wanting reassurance that their training is being guided by someone with a deep understanding of the body. “I love helping people achieve their goals, no matter where they’re starting from,” he says. “Everyone starts somewhere.” A Training Style That Keeps People Coming Back If Josh had to describe his coaching style in three words, it would be fun, fun, fun. But make no mistake, behind the smiles and conversation is structured, intelligent programming. Josh believes enjoyment is not a bonus, it’s essential. When people enjoy training, they stay consistent, and consistency is where results are built. His favourite movement to coach is the squat, a foundational pattern that shows up everywhere in daily life. “It’s such an important movement,” Josh explains. “And it can be adapted in so many ways, for strength, control, rehab, or performance.” Sessions with Josh are supportive, encouraging, and tailored to each client’s capacity on the day. He focuses on small, sustainable improvements, backing clients to chase that extra one percent over time. Transformations That Truly Matter One of Josh’s most meaningful coaching experiences involved working with a client who had battled leukaemia three times. When they first began training, she could only manage 20 minutes of exercise. Over time, with consistent support and encouragement, she progressed to full one-hour sessions and was able to return to acting, her true passion. “That’s the stuff that stays with you,” Josh says. “Training isn’t just about fitness. It’s about giving people their lives back.” Life Outside the Gym When Josh isn’t on the gym floor at CGPT, he’s usually playing or following cricket, reading, watching films, or spending time with his girlfriend. A self-confessed movie buff, he enjoys unwinding away from the gym just as much as he enjoys bringing energy into it. And if you’re lucky, you might even hear his surprisingly accurate Donald Duck impression, a hidden talent that usually catches clients completely off guard. Why Train With Josh at CGPT? Josh Martin is the kind of trainer who makes people feel comfortable from day one. His blend of clinical exercise physiology knowledge, personal experience with injury, and genuinely upbeat coaching style makes him an invaluable part of the CGPT team. Whether your goal is returning to training after injury, building strength safely, or simply finding a personal trainer in Hawthorn who makes the gym feel less intimidating, Josh brings empathy, structure, and positivity to every session. As Josh puts it best: “Let’s have some fun, and let’s get you moving. Even one small step is a big step in the right direction for your health.” 

Common Gym Myths Debunked: The Truth About Getting Stronger, Leaner, and Healthier The fitness world is full of noise - and unfortunately, a lot of myths. From “lifting makes you bulky” to “cardio is the only way to lose weight,” misinformation has kept far too many people stuck, frustrated, and spinning their wheels. At CGPT in Hawthorn , we believe in cutting through the noise with what actually works: evidence, not hype. Whether you’re just starting your training journey or looking to refine what you’re already doing, understanding the truth behind these myths can completely change the way you see exercise. Let’s set the record straight on six of the most common misconceptions that hold people back from achieving lasting results. Myth 1: “Lifting Makes You Bulky” One of the most persistent myths in fitness, especially among women, is the fear that lifting weights will lead to oversized, bulky muscles. The reality: Building large amounts of muscle takes years of dedicated, high-volume training, a calorie surplus, and very specific programming. For most people - particularly those training a few times a week and maintaining a balanced diet - strength training leads to a leaner, more toned body composition, not bulk. Research shows that women typically have 10 - 30 times lower testosterone levels than men (Kraemer et al. 1998), making extreme hypertrophy naturally limited. What strength training does do is: · Increase muscle definition and firmness · Improve metabolism and fat utilisation · Enhance long-term weight maintenance In fact, studies confirm that resistance training not only preserves lean mass during weight loss but improves metabolic rate, making fat loss easier and more sustainable (Willis et al. 2012). 💡 Takeaway: Lifting weights shapes your body - it doesn’t inflate it. Myth 2: “Sweating More Means a Better Workout” Sweat has become a misguided badge of honour in the fitness world. But the truth is, it’s simply your body’s way of cooling itself, not an indicator of effort or effectiveness. The reality: Progress comes from the quality of your movement, appropriate intensity, and consistent progression - not how soaked your shirt is. Factors like room temperature, genetics, and hydration levels influence sweat output far more than workout quality. A perfectly executed strength session with good form and control might produce minimal sweat but deliver maximum results for muscle, strength, and metabolism. As exercise physiologist Dr. John Hawley (Australian Catholic University) explains, adaptation comes from mechanical tension, not perspiration - the repeated challenge that signals the body to get stronger and more efficient. 💡 Takeaway: Don’t chase sweat. Chase progress. Myth 3: “You Need to Train Every Day to See Results” More isn’t always better - especially when it comes to training. The reality: Most people make their best progress training two to four times per week, with adequate recovery between sessions. Strength improvements come from the body repairing and rebuilding after training - a process that requires rest and proper nutrition. Exercising daily without recovery increases the risk of fatigue, injury, and burnout. Studies show that muscle protein synthesis remains elevated for up to 48 hours after resistance training (MacDougall et al. 1995), meaning more frequent sessions often deliver diminishing returns. At CGPT, we see far better outcomes when training programs are structured and intentional, not relentless. Rest is part of progress, not the absence of it. 💡 Takeaway: Training smarter always beats training harder. Myth 4: “Cardio Is the Only Way to Lose Fat” It’s true that cardio helps burn calories and supports cardiovascular health. But when it comes to sustainable fat loss and body composition change, strength training wins every time. The reality: Strength training increases resting metabolic rate by building and maintaining muscle - meaning you burn more energy even while resting. In contrast, excessive cardio can lead to muscle loss if not balanced with resistance work and adequate nutrition. A landmark study published in Obesity found that combining strength training with moderate cardio led to greater fat loss and better weight maintenance than cardio alone (Willis et al. 2012). Similarly, resistance training has been shown to reduce visceral fat - the harmful fat around organs - even without major changes to body weight (Strasser & Schobersberger 2011). 💡 Takeaway: Cardio trains your heart. Strength training transforms your body. Myth 5: “Women Should Train Differently Than Men” This myth is outdated and unsupported by science. The reality: Muscles respond to the same principles of training regardless of gender. Both men and women benefit from progressive overload (gradually increasing challenge over time), proper technique, and balanced programming that includes strength, mobility, and recovery. Where the difference lies is in individualisation, not gender. Women’s hormonal fluctuations, life stages (such as pregnancy, postpartum, or menopause), and recovery needs may influence how training is structured but the physiological mechanisms of building strength remain identical (Haizlip et al. 2015). Research published in the Journal of Applied Physiology found that men and women experience comparable relative strength and hypertrophy gains when training under similar conditions (Hubal et al. 2005). 💡 Takeaway: The principles of strength training are universal. The best programs are simply tailored to you. Myth 6: “Lifting Is Bad for Your Joints” This myth couldn’t be further from the truth - when done correctly, lifting protects your joints rather than harms them. The reality: Strength training improves joint health by strengthening the muscles, tendons, and connective tissues that support and stabilise them. It enhances joint range of motion, improves balance, and reduces pain associated with conditions like arthritis. In a meta-analysis published in the British Journal of Sports Medicine, researchers found that resistance training significantly improved pain and function in adults with osteoarthritis (Fransen et al. 2015). Controlled loading, rather than avoidance, is what keeps joints healthy over time. The key is proper technique, progressive loading, and professional supervision - all of which are central to how CGPT programs are designed. 💡 Takeaway: Done right, lifting is joint therapy, not joint stress. Bringing It All Together: What Actually Works Real results in the gym come from three things: 1. Consistency – showing up regularly enough for your body to adapt. 2. Progressive Challenge – gradually increasing intensity to keep improving. 3. Recovery – allowing your body to repair, rebuild, and grow stronger. It’s absolutely not about trends, extremes, or doing more. It’s about balance: the kind that supports strength, mobility, mental clarity, and long-term health. At CGPT, every program is built on these principles. Our private, evidence-based environment removes the confusion of fad fitness and replaces it with science, structure, and support. Whether you’re starting fresh or refining your training approach, you’ll find clarity, confidence, and a system that works.
