Mind Over Muscle: How Mental Training Improves Physical Performance for Women in Midlife

When I created my own 24-hour UltraQuad endurance challenge at 57, the voice in my head wasn’t entirely supportive. “You’re not young enough for this.” “What are you trying to prove?” “This is going to hurt.”
Does this sound familiar?
What that inner critic didn’t understand is that I do hard things because of my age, not despite it. Every challenging physical pursuit, from cold water swimming to endurance events, becomes a conversation with my physiology rather than a battle against it.
This distinction matters more than you might think. When people ask me how I can take on these challenges, I always say they’re as much a mental test as a physical one.
Why Your Approach to Challenge Matters
When we approach physical challenges as something to conquer, dominate, or survive, we activate our sympathetic nervous system—the fight-or-flight response. Stress hormones flood our system. Our muscles tense. Our breathing becomes shallow. We literally work against ourselves.
But when we approach the same challenge as a collaboration with our body, something shifts. We engage our parasympathetic nervous system alongside the sympathetic. We find flow states and we access reserves of strength we didn’t know existed.
The Science of Mind Over Muscle
Research consistently shows that mental state directly impacts physical performance. Perceived exertion studies demonstrate that when we expect something to be difficult, it becomes more difficult and our brain actually recruits fewer motor units. Meanwhile, visualisation research shows that mental rehearsal activates the same neural pathways as physical practice, improving performance without moving a muscle.
Self-talk studies reveal something even more remarkable: positive internal dialogue can increase strength output by up to 24%. And flow state research confirms that when we’re fully present and engaged, we access greater endurance, strength, and coordination.
This isn’t about toxic positivity or pretending things don’t hurt. It’s about changing your relationship with discomfort.
From Surviving to Thriving: A Personal Experience
During that 24-hour challenge, there were moments when every cell in my body screamed to stop. The former me would have gritted through it, fighting every step. Instead, I started asking different questions: What is my body actually telling me? Can I soften around the discomfort rather than bracing against it? What if I thanked my legs for carrying me rather than cursing them for hurting?
This shift from resistance to curiosity transformed the experience. The physical discomfort didn’t disappear, but my relationship with it changed completely.
The Hormonal Connection for Women in Midlife
For women navigating perimenopause and menopause, this mind-body connection becomes even more critical. Declining oestrogen affects our stress response, recovery, and pain perception. When we layer performance anxiety or negative self-talk on top of these hormonal changes, we create a perfect storm of underperformance.
But when we train our mental state alongside our physical capacity, we can actually work with these changes rather than against them. Mindful training reduces cortisol production. Positive visualisation improves recovery. Present-moment awareness enhances motor control. Self-compassion speeds healing.
Practical Mental Training Strategies
Here are techniques I use with my clients and in my own training:
Before Training
Create a mental transition before you begin. This might be three deep breaths with a positive intention, a gratitude practice for your body’s capability, or visualising successful movement patterns.
During Training
Notice your self-talk and consciously shift it. Instead of “This is too heavy,” try “This is challenging me perfectly.” Rather than “I can’t do this,” perhaps “I’m learning to do this.” Replace “I’m too old” with “I’m experienced and strong.”
Focus on process rather than outcomes. Instead of fixating on lifting a certain weight, concentrate on maintaining form, breathing through each rep, or staying present with the movement.
During challenging sets, practice what I call “discomfort meditation.” Notice where you feel tension. Breathe into those areas. Soften what doesn’t need to be engaged. Thank your body for its effort.
Remind yourself of past achievements and break things down. Tell yourself you’ve done harder things before. Tick off progress in manageable chunks—one quarter done, halfway there and so on.
After Training
Take time to acknowledge what you accomplished. Note one thing that felt powerful. Set an intention for recovery.
The Ripple Effect
When you master your mental state during physical challenges, it ripples into every area of life. The confidence you build in training becomes courage in work meetings. The resilience you develop through exercise becomes emotional strength in relationships. The presence you cultivate during a cold water swim becomes mindfulness in daily life.
Finding Your Challenge
You don’t need to sign up for 24-hour endurance events to apply these principles. Your challenge might be returning to exercise after years away, lifting weights for the first time at 60, managing chronic pain while staying active, or simply showing up consistently when motivation wanes.
Whatever your challenge, remember that your mental state is as trainable as your muscles. The thoughts you bring to your training shape your results as much as the programme you follow.
Try This
​Choose one training session this week to practise training from the inside out:
Set a mental intention before you begin. Monitor your self-talk throughout. When things get difficult, get curious rather than critical. Practise one discomfort meditation technique. End with acknowledgment and gratitude.
Notice what shifts when you train your mind alongside your body. You might discover that your greatest strength lies not in your muscles, but in the conversation between your mind and body.
