How to stay fit in your 40s and 50s: Realistic fitness routines that work

Midlife Fitness: Real Talk from a 49-Year-Old Woman on a Mission

At 49, staying fit isn’t about chasing a flat stomach or hitting a dress size anymore. It’s about energy, resilience, confidence and showing up for myself every single day. I’m currently taking on a personal health mission and I call it my 50 in 50 Challenge. It involves achieving 50 wellness wins in the year I turn 50. And yes, some days it’s tough. But it’s real, and it’s working.

You can feel fit and strong again in your 40s or 50s. You don’t need to overhaul your entire life. You just need a realistic fitness routine that fits your lifestyle, your body, and your mindset. Let me share what’s working for me, and what might help you too.

Why Fitness in Midlife Is Different (and Better)

We juggle a lot in our 40s and 50s. Parenting and careers demand our attention. Changing hormones and a body that might not recover as fast add to the complexity. For example, I’ve suffered with Achilles tendinitis which literally stopped me in my tracks for a while. But midlife is the perfect time to focus on strength and self-care. I found that adding in calf raises into my weekly routine made a real difference. Fitness at this stage of life is less about punishment and more about purpose.

That means:

• Protecting bone and muscle mass
• Supporting hormonal balance (perimenopause!)
• Boosting mood and mental clarity
• Feeling strong – not skinny

My Realistic Midlife Fitness Routine

Here’s what my weekly training schedule looks like as part of my 50 in 50 challenge:

Monday – Strength Training (Upper Body)

Focus: Dumbbell presses, rows, shoulder presses
Goal: Preserve lean muscle, support posture.

Tuesday – Body Pump, Blaze, or Zumba

Focus: High-energy, full-body cardio with punches and kicks.
Goal: Heart health and stress release.

Wednesday – Active Recovery

Focus: Walking, mobility stretches, and foam rolling.
Goal: Give my joints a break and stay mobile.

Thursday – Strength Training (Lower Body)

Focus: Squats, lunges, and deadlifts.
Goal: Improve lower body power and prevent injury.

Friday – Spin Class or HIIT Session

Focus: Low-impact, high-output training.
Goal: Boost stamina and sweat out the stress.

Saturday – Full on everything – three back-to-back classes

Focus: Core strength, flexibility, breathwork.
Goal: Hormonal balance and joint care.

Sunday – Strength training

Focus: Reset and reflect on my progress.

How I Stay Consistent (Even When Motivation Dips)

• Track Progress: I log my workouts and small wins as part of my 50 in 50 challenge. I celebrate consistency over perfection.
• Keep It Flexible: If I miss a day, I don’t panic. I adjust and carry on.
• Eat to Train, Not Diet: I fuel my workouts with protein, slow-release carbs, and hormone-supportive fats.
• Find Joy in Movement: I don’t do any workouts I hate. Movement has to energise me, not exhaust me or make me feel as though I’m failing.
• Use Visual Reminders: I keep my workout clothes visible during the day. It’s all about reducing excuses on an evening.

My Top Tips for Staying Fit in Your 40s and 50s

• Give yourself grace: Midlife isn’t the end. It’s the reinvention.
• Start slow, but start now: Even 10 minutes a day can rebuild strength and stamina.
• Prioritise protein and hydration: Nutrition matters more than ever in midlife.
• Lift weights seriously: It’s the most powerful tool for body composition and confidence.
• Sleep is sacred: Fitness gains are made during rest, not just reps.

Fitness Is a Gift, Not a Grind

If you’ve ever thought, “It’s too late to get fit,” I’m here to tell you it’s not. You don’t need to train like an athlete or overhaul your lifestyle. Just find routines that work for your body now, not the one you had in your 20s.

My 50 in 50 challenge isn’t about perfection. It’s about progress, energy, and enjoying the second act of life with power and presence. I hope this inspires you to move in a way that supports your goals and brings you joy. You’ve got this, one workout, one walk, one win at a time.
