Why Strength Training Becomes Even More Important After 35 — And How One Session Can Change Your Next 24 Hours

When most people think of strength training, they picture athletes lifting heavy weights to perform better in sport. But the truth is, strength training isn’t just for athletes, it’s for everyone. And once you hit your mid-30s, it becomes one of the most important investments you can make in your health, fitness and longevity.

In fact, the benefits go far beyond stronger muscles. Strength training can have a ripple effect that carries into your mood, focus, energy levels and even the decisions you make over the next 24 hours.

Let’s break it down.

Why Strength Training Matters More As We Age

From around the age of 30, our bodies naturally begin to lose muscle mass and strength, a process called sarcopenia. Left unchecked, this can lead to reduced mobility, slower metabolism, higher injury risk and even a loss of independence later in life.

Here’s why strength training becomes your best defence after 35:

1. Preserves & Builds Muscle Mass: More muscle means you burn more calories at rest, maintain mobility and have the strength to do the things you love, whether it’s playing with your kids, carrying groceries, or tackling weekend adventures.

2. Strengthens Bones: Weight-bearing movements help improve bone density, reducing the risk of osteoporosis and fractures as you get older.

3. Boosts Metabolism: Muscle tissue is metabolically active, so keeping it strong helps offset the natural slowing of your metabolism with age.

4. Supports Joint Health & Injury Prevention: Strength training strengthens not just muscles, but also the ligaments and tendons around your joints, keeping you more resilient and less injury-prone.

5. Improves Balance & Coordination: Essential for preventing falls and maintaining independence later in life.

The 24-Hour Domino Effect of One Strength Session

One of the most underestimated benefits of strength training isn’t just physical, it’s mental. A single session can trigger a cascade of positive behaviours and feelings for the rest of your day.

Here’s how that domino effect often plays out:

• Immediately After Training – Your body releases endorphins and dopamine, leaving you feeling accomplished, uplifted and more confident.

• The Next Meal – Because you’ve invested effort in training, you’re more likely to make healthier food choices that align with your goals.

• Energy Levels – Training increases blood flow, oxygen delivery and mitochondrial activity, leaving you more alert and energised for work, family, or personal projects.

• Mindset Shift – The discipline of showing up for a session builds self-trust, reinforcing the idea that you can follow through on what you set out to do.

• Stress Buffer – Exercise reduces cortisol levels, making you more resilient to challenges and frustrations for the rest of the day.

• Sleep Quality – Your body’s need to recover after training often improves sleep depth and quality that night, which sets you up for an even better tomorrow.

  
  

It’s Not Just About the Gym, It’s About Life

When you commit to strength training, especially as you move through your 30s, 40s and beyond, you’re not just improving your ability to lift weights, you’re improving your ability to live life on your terms.

You’ll move better, think clearer, sleep deeper and carry yourself with more confidence. And because of that 24-hour domino effect, one decision to train can influence dozens of small choices that make you healthier, stronger and happier.

So next time you’re debating whether to train, remember this: it’s not just about the muscles you build, it’s about the momentum you create.
