DRAFT: Nature vs Nurture

Caitlyn Davey • April 2, 2025

On the recent podcast episode of Rebuild Health and Fitness, podcast guests and fitness power couple, Steve Cook and Morgan Rose Moroney discussed various topics including the nature vs. nurture debate when it comes to health and fitness.  Nature vs. nurture  Although hard work is important when it comes to personal fitness level, genetics also plays a major role. Steve discussed his natural acumen for strength training as a child, for instance how he could bench 225 pounds while only in Grade 6. “I loved being that strong kid,” he said.  “Training is the realization of ones genetic potential,” Morgan added quoting Ross Edgely, an extreme adventurer. “Nurture isn’t spoken about as often as it should be,” she said. Morgan adds that although her parents have “great genetics in terms of sports and movement,” her training varied dramatically from them as she decided to go into gymnastics, a sport she declares she was decidedly not built for. “Its a combination of both, and they are just as important as the other,” she concluded.  Genetics particularly play a role the more specialized you get into an area of fitness, Steve explained, citing examples of “Sherpas in Nepal,” and “Jamaicans and sprinting”. As you get closer and closer to “that peak, genetics are going to play a role.” Everyone who goes to the Olympics is working hard, but some people have that genetic advantage, Steve said, giving Micheal Phelps as a great example of someone who has a swimmers body. “You don’t see many 5’10 dudes in the NBA for a reason.”  Maintenance “Its so much easier to stay in shape than to get in shape,” Steve says, discussing maintenance volume. Even while traveling just 30-45 minutes of “solid work” can be enough for maintaining muscle mass/ flexibility. “If you’re a runner or a gymnast you have that muscle memory,” he adds. Podcast host … also adds that he has personally observed people who used to be athletes who haven’t “lifted in years,” and within “2-3 weeks are shifting phenomenal amounts of weight.”   Tips for parents  “Getting kids into”, either gymnastics, body weight exercises, soccer, AFL, rugby,  flexibility and mobility is what Steve recommends for parents “looking to create the perfect athlete,” like his father.  Important considerations  Steve discussed how until recently he thought that lifting weights stunting children’s growth was a myth, until he heard the contrary from Andrew Hubermann, a neuroscientists, podcast. “Most of the research looks away from that,” podcast host …, contradicts, “what’s the detriment, I reckon there’s more positive,” he adds.  Moving on to the topic of gymnastics and delayed puberty, Steve said that he thinks that is because of the low body fat percentage in gymnasts, “They do so much volume, I just don’t think that their energy needs are being met,” podcast host adds.  “We used to pack 3 lunchboxes”, Morgan adds. Despite this, “I was so small when I was in gymnastics,” Morgan said, until she hit puberty when she was around 17/18- when she stopped her gymnastics training. “I had not grown from 12-17,” she said.  Main Takeaways  Both genetics and hard work play an important role when it comes to peoples fitness levels. When it comes to higher levels of training in particular genetic and evolutionary advantages are what can set some apart from others.  Maintaining muscle mass and flexibility is relatively easy compared to building it up, however it can also be lost quite easily.  When it comes to children, sports and general exercise is very important, however especially for children who are training to become athletes there are some debates to keep in mind such as whether or not lifting weights stunts growth, and the impacts that gymnastics training has on puberty.

If you live in Wynnum or Capalaba, you’re not short of fitness options. There are 24-hour gyms. Bootcamps. HIIT studios. Yoga classes. Running clubs along the waterfront. But despite more access than ever, many people still feel stuck. Tired. Plateaued. Unsure whether what they’re doing is actually working. For many adults across Brisbane’s bayside suburbs, the missing piece isn’t more cardio or more intensity. It’s structured strength training. What Strength Training Actually Does (Beyond “Toning”) Strength training isn’t just about lifting heavy weights or looking muscular. It is one of the most well-supported interventions in exercise science for improving: • Lean muscle mass • Bone density • Insulin sensitivity • Resting metabolic rate • Functional capacity • Injury resilience When you lift weights progressively, your body adapts. Muscle fibres increase in size. Neural drive improves. Connective tissue strengthens. Bone responds to load. This isn’t aesthetic. It’s physiological. For adults in their 30s, 40s and 50s — especially busy professionals and parents — maintaining and building muscle becomes increasingly important. From around age 30 onwards, we gradually lose muscle mass if we don’t train against resistance. Strength training slows — and can even reverse — that decline. Why Many People Plateau in Traditional Gyms Joining a gym in Wynnum or Capalaba is easy. Progress is harder. Many people follow random workouts. They jump between machines. They try classes without a long-term plan. They train hard, but without structure. The body adapts quickly to repeated stimulus. If load, volume or intensity don’t increase over time, adaptation stalls. This principle is called progressive overload — and it is fundamental to strength development. Without it, workouts feel hard but don’t necessarily lead to measurable progress. That’s why tracking lifts, planning training blocks, and adjusting volume matter. Effort is important. Structure is essential. Strength vs “Burning Calories” A common goal across the Wynnum and Capalaba community is fat loss. Many people default to high-intensity cardio to “burn more calories”. While cardiovascular training improves heart health and work capacity, resistance training changes body composition in a different way. Muscle tissue is metabolically active. The more lean mass you maintain, the more energy your body requires at rest. Strength training also improves glucose regulation and insulin sensitivity, which influences how your body uses carbohydrates. In simple terms: Cardio burns calories during the session. Strength training improves how your body uses energy long term. The most effective approach often combines both — but strength should not be overlooked. The Importance of Coaching in Strength Training Not all training environments are equal. There is a difference between access to equipment and access to coaching. Research in motor learning consistently shows that technique improves faster and more safely when feedback is specific and timely. Good coaching reduces injury risk, improves force production and builds confidence under load. For beginners, this means learning correct movement patterns. For experienced lifters, this means refining efficiency and progressing safely. In both Wynnum and Capalaba, more people are moving away from “do it yourself” gym models and towards coached environments that prioritise progression and accountability. Because consistency — not intensity — predicts long-term success. Strength Training for Real Life The real benefit of strength training isn’t what happens in the gym. It’s what happens outside it. Carrying children. Lifting groceries. Walking the stairs without fatigue. Reducing back pain. Improving posture after long desk hours. Strength improves quality of life. For people living and working in Brisbane’s bayside suburbs — balancing work, school runs and community commitments — training needs to support life, not compete with it. Two to four well-programmed sessions per week is enough to create significant improvements in strength and body composition when done consistently. You do not need to train every day. You need to train intelligently. What To Look For in a Strength Training Gym in Wynnum or Capalaba If you’re considering starting strength training locally, look for: • Structured programming rather than random workouts • Progressive overload built into sessions • Coaches who adjust for injury, mobility and experience • A community that supports consistency • A clear pathway for beginners Strength training should feel challenging — but sustainable. It should build confidence, not intimidation. A Quiet Shift in Fitness Across Wynnum and Capalaba, there is a noticeable shift. People are moving away from extreme short-term “transformations” and towards long-term strength development. They want: Energy that lasts. Bodies that feel capable. Training that fits into real life. Strength training isn’t a trend. It is one of the most researched, effective and sustainable forms of exercise available. If you’ve tried everything else and still feel stuck, it might not be motivation you’re missing. It might be structure. And structure changes everything.
