Perimenopause is one of the most significant biological transitions women experience, yet it's rarely talked about in fitness spaces. If you're in your 40s or 50s and suddenly finding that your body feels different, your energy fluctuates wildly, or your usual training routine isn't working anymore — you're not alone, and you're not imagining it.
At Fortitude Gym in Lydney, we've supported countless women through this stage of life. We've learned that perimenopause isn't something to push through or ignore — it's a time that calls for understanding, adaptation, and compassionate coaching. This guide will help you navigate training during perimenopause with confidence and clarity.
Perimenopause is the transitional phase leading up to menopause, typically lasting several years. During this time, oestrogen levels fluctuate significantly before eventually declining. This hormonal shift doesn't just affect your reproductive system — it impacts nearly every aspect of your physical and mental wellbeing.
Oestrogen plays a critical role in:
When oestrogen levels drop during perimenopause, all of these systems can be affected. This explains why you might suddenly experience weight gain, joint stiffness, poor sleep, brain fog, mood swings, or decreased motivation — even when you're doing everything "right."
Here's the good news: research shows that while perimenopause can be challenging, life satisfaction actually increases in the years following menopause. The graph showing the "U-curve" of life satisfaction during menopause tells an important story — yes, perimenopause can be tough, but it gets better. Much better.
With the right support, training approach, and mindset, you can not only navigate this transition successfully, but emerge stronger, more confident, and more resilient than before.
The key message? Be kind to yourself through perimenopause, eat adequate protein, lift weights, and your future self will thank you.
If there's one thing women in perimenopause need to prioritize, it's strength training. Here's why:
Women lose approximately 0.7% of muscle mass per year after the age of 30. This accelerates during perimenopause due to declining oestrogen and reduced muscle protein synthesis. Less muscle means:
The solution? Regular strength training combined with adequate protein intake can prevent and even reverse this muscle loss.
Rapid decreases in bone density occur during perimenopause — women can lose up to 15% of bone density in the years leading up to menopause. This dramatically increases the risk of osteoporosis, fractures, and falls.
Strength training is one of the most effective ways to maintain and build bone density. When you lift weights, you're not just building muscle — you're telling your bones to stay strong and resilient.
Declining oestrogen affects tendon elasticity and ligament integrity, leading to increased soft tissue injuries, tendinopathies, and joint stiffness — particularly in the Achilles, knees, and shoulders.
This is why expert coaching matters. Regular training at the right intensity, with proper form and progressive loading, helps keep your joints healthy and reduces injury risk. At Fortitude, we prioritize movement quality and smart progression to keep you training safely for life.
Training through perimenopause requires a different approach than training in your 20s or 30s. Here's what matters most:
During perimenopause, your body is already under significant hormonal stress. Adding excessive training intensity on top of that can backfire, leading to poor recovery, increased injury risk, and burnout.
Instead, focus on:
Research shows that behavior-focused goals (like "train 3 times per week") are more effective during perimenopause than performance-focused goals (like "hit a new personal best"). Prioritizing consistency keeps you moving forward without adding unnecessary stress.
Some days you'll feel strong and energized. Other days, you'll feel exhausted before you even start. This isn't weakness — it's biology.
It's okay to strip back your intensity. Low-impact recovery sessions, mobility work, or lighter training days are sometimes necessary to maintain consistency and protect your body long-term. Your coach should understand this and adapt your programming accordingly.
Hot flashes, night sweats, and temperature regulation issues are common during perimenopause. These aren't just uncomfortable — they can impact your ability to train effectively.
Practical strategies:
Perimenopause can leave your nervous system feeling dysregulated, leading to anxiety, irritability, and poor recovery. Simple breathing techniques before or after training can help activate the parasympathetic nervous system, promoting calm and recovery.
Try:
Training alone can feel isolating, especially when you're navigating a challenging phase of life. Finding a group of like-minded women to train with provides:
At Fortitude, this sense of community is one of the things our members value most. You're not just joining a gym — you're becoming part of a supportive group that shows up for each other.
Many people who haven't experienced perimenopause don't understand the profound impact that hormonal fluctuations can have on physical and mental wellbeing. This is why compassionate, informed coaching is so important.
What this looks like in practice:
At Fortitude, we believe that perimenopause is a period of time where we need to provide support, understanding, and a safe environment to encourage continued regular activity. Because staying active through this transition isn't just about fitness — it's about your long-term health, independence, and quality of life.
If you're navigating perimenopause right now, here's what you need to focus on:
Aim for at least 2-3 strength sessions per week. Focus on compound movements (squats, deadlifts, presses) that build functional strength and bone density.
Aim for 1.6-2.2g of protein per kilogram of body weight daily to support muscle maintenance and recovery. Protein becomes even more critical during perimenopause.
Some weeks you'll train 4 times. Some weeks you'll manage 2. Both are wins. Show up when you can, and be kind to yourself when life gets in the way.
If you're working with a coach, tell them what you're experiencing. Good coaches will adapt your programming to support you, not push you into the ground.
Train with other women who understand what you're going through. The support, encouragement, and shared experience will keep you motivated on tough days.
This isn't about fitting into a dress or looking a certain way. This is about building strength, resilience, and independence so you can live well for life.
Perimenopause is challenging, but it doesn't have to derail your fitness journey. With the right approach — one that prioritizes strength training, consistency, compassionate coaching, and community support — you can navigate this transition successfully and come out stronger on the other side.
