5 Frequently Asked Questions We Get As Nutrition And Health Experts

Caitlyn Davey • July 8, 2025

Five important questions from a health perspectiveAs coaches and nutritionists, Sean and James are constantly being asked for tips and advice on health and fitness-related things. On episode 51 of the Rebuild Health and Fitness Podcast, we discuss some common questions that people ask regarding health and nutrition.  Should you have protein before bed? There are some advantages to having your largest serving of protein before bed. In terms of sleep science, the earlier you can have your last meal, the better. Say you have your meal at 6pm and go to bed at 9pm; that will enhance your sleep quality because your body won't be working as hard digesting food as you sleep. This means that your body's going to be in a more restful state, not working hard while you're trying to rest.  Can I take pre-workout before a team sport or game, and will it improve my performance?Yes, if you want. But it’s trial and error - if you think pre-workout helps improve your performance in a team sports environment, go for it. But we need to remember the main thing that gets you going from pre-workout is the caffeine that acts as a stimulant. And we can't underestimate the placebo effect that has.  The research shows that caffeine is massive. A lot of caffeine does this for you, usually 2-6 milligrams of caffeine per kilo of body weight. This will vary then depending on caffeine tolerance. So, to get the effect that you want, you’re probably talking 5-6 milligrams of caffeine, which is a hell of a lot of caffeine. One of the most significant contributors is, what time is your game? If it’s midday Saturday - go for it. But if you’re playing a night-time game of basketball at 8pm, we would probably advise you not to because then your sleep will be affected. From a general training standpoint, for our members in the gym, we generally advise not having pre-workout in the afternoon just because it's going to mess with your sleep so much. And that's going to be more detrimental to your training and recovery over the coming days and weeks. I train 1-2 hours of strength and conditioning training, six days a week. Is it a sufficient amount of training for someone who sits for eight hours a day? Yes, definitely. In terms of progress, we don't know if you're talking about overall health, but constantly moving will be more beneficial. If we can train and then we can move as much as possible throughout the day, that will be more beneficial than just sitting there. But it comes down to the optimal-suboptimal scenario. If I was going to build muscle and did not want to lose any of my gains sitting for eight hours and not moving, then training for two hours at the gym, that’s probably pretty good. For optimal health or maybe weight maintenance or loss -  that’s certainly enough training.  In your opinion, what are the most important factors for optimal health?Talking specifically, physical, training, nutrition; we’ve mentioned a million times, health is more than training and nutrition. Training and putting yourself in a hole or challenging yourself is so important and valuable. We spoke about that on the discomfort podcast, we need these challenges to overcome because it makes us more resilient. Nutrition plays a role in that; a good little rule is always the 80-20 rule. 80% of the time – good and nutritious foods, 20% of the time you have the freedom to whatever you want. But f you go too far the other way, that will negatively affect your training and body composition and then your head. Everything is on a bit of a spectrum in it. For optimal health: training, taking care of your nutrition, having a social life, managing stress, and sleeping well are of utmost importance.  What are some good pre or post-workout snacks and meal ideas for building muscle and dropping body fat?The simple rule of thumb we like to use is that it depends on how far before the training session you will be eating. If you have 20-40 grams protein plus carbohydrates, anywhere from 45 minutes to 3 hours before, will do pretty well. As for post-training, just have some protein; you don't need to have carbohydrates – you could have some, but there’s just not any added benefit for muscle growth and repair.  If you have burning questions about health, listen to the podcast below, or if you want help with your nutrition, get in touch with our team.

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.
