How Your Menstrual Cycle Can Affect Your Training (And What To Do About It)

Caitlyn Davey • July 8, 2025

It’s not a widely discussed topic, but it’s one that roughly half of the population deals with – periods. It affects your mood, your strength, your weight, your calorie output, among other things. Women in the gym can struggle to get the most out of their sessions, some research has shown women see a 60% reduction in strength from one week to another due to cycles. This week on the Rebuild Health & Fitness podcast, we speak to Sarah Boyer - a qualified coach and nutritionist, who focuses on training females and is a female herself, thus giving some good insight into the effects of periods and cycles on training and health. It’s not a widely discussed topic, even within the industry, James says. “During uni for me, any sports team, nothing was ever mentioned about the female menstrual cycle.” THE CYCLEThe menstrual cycle is broken up into different phases:James says: “There are different phases of the cycle, there’s follicular, which we’ll call your more positive weeks.' This is the time between your first day of your period and your ovulation.  “Then you have your ovulation – when you’re most fertile, when you’re horniest, and then you have your luteal phase, which is post-ovulation, you have an increase in your metabolic rate, you have more insulin resistance at the same time and all the things in this phase are not spoken about.” The luteal phase, the time from ovulation to menstruation – which is typically about 14 days – this is when premenstrual syndrome happens, this is when you'll find training a little more challenging and adhering to your nutrition can be more difficult. Your menstruation happens between your luteal and follicular phases, that is your period, which is when the uterus lining sheds.  Sarah says the luteal phase is a time when women will burn more calories and is a time for self-compassion, it's when we see estrogen and progesterone rising and testosterone drops - which means that you may feel like you have less energy. “You get to that week three – where we understand that you see the progesterone levels getting higher and women can burn 100-300 calories more per day; no wonder we get hungry and want chocolate.“We have this pressure that we should be eating the same way every day or that we should feel the same amount of energy every day. But we don’t get to. In that second phase of our cycle, we get hungrier and we can mentally feel worse too – and that’s a killer combination.” Sean agrees, outlining with some of his clients that they opt for a two-week-on, two-week-off nutritional programme. He says: “Dieting with female clients – there are two weeks within the cycle where it’s not optimal to be on an aggressive diet, especially when you’re needing those extra calories each day. And some people get confused- it’s not over a week that you need 100-300 extra, it’s each day during that part of your cycle.” Knowing where you are in your cycle can help you adhere to your training plans and accommodate your body’s requirements. Sarah says: “You don’t start a diet halfway through your cycle, when you’re about to become moody, about to start overthinking, about to start to become mildly irrational, you could feel more bloated and lethargic and you may need more food. You don’t start going into a (calorie) deficit then.” While these phases are important to know, you can’t really stop them from happening but you can train and eat around them.  Fitr Woman is one useful app the team recommends for tracking that can offer insight into how to train according to your cycle. James says: “There’s nothing you can really do about this from a training aspect, but you must understand it. The more we understand it as male coaches, and as females – the less guilt I think people will have.” Hear more about training and menstrual cycles on the Rebuild Health & Fitness podcast, available on Apple Podcasts, Spotify, Google Podcasts or wherever you stream your podcasts.

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.
