Why Do I Keep Getting Niggles in My 40s? (And what you can do about it).

If you’ve hit your 40's and suddenly feel like your body is whispering (or shouting) at you more than it used to, you’re not imagining it. Those little aches, tight spots, and recurring “niggles” can feel frustrating, especially if you’ve always been active.

The good news is this isn’t the beginning of the end, it’s simply your body asking for a different kind of support.

What’s Behind the Niggles?

1. Hormonal Changes Are Shifting the Game

As we move through perimenopause, levels of oestrogen and progesterone begin to fluctuate.

Oestrogen, in particular, plays a big role in:

• Muscle repair

• Tendon and ligament health

• Reducing inflammation

As levels decline, tissues can become less resilient, meaning they don’t recover as quickly and are more prone to irritation.

2. Recovery Isn’t What It Used to Be

You might be doing the same workouts you did in your 30's… but your body isn’t responding the same way. Why?

• Slower muscle repair

• Increased inflammation

• Higher overall stress load (hello, work + kids + life)

Without enough recovery, small strains can linger — and turn into persistent niggles.

3. Loss of Muscle Mass and Strength

From our 30's onwards, we naturally start to lose muscle mass (a process known as Sarcopenia).

Less muscle support around joints means:

• More strain on tendons and ligaments

• Reduced joint stability

• Greater risk of overuse injuries

  
  

4. Movement Patterns Catch Up With You

Years of sitting, carrying kids, working at desks, or favouring one side of your body can create imbalances.

These don’t always show up immediately, but over time, they lead to:

• Tight hips

• Weak glutes

• Rounded shoulders

• Poor core engagement

And eventually… niggles.

5. You’re Still Training Like You’re 25

This is a big one.

Pushing through fatigue, skipping warm ups, or going all out every session might have worked before, but now it often backfires. More intensity isn’t always better. Smarter training is.

So, What Can You Do About It?

1. Prioritise Strength Training

Strength training becomes non negotiable in your 40s.

It helps:

• Build muscle and protect joints

• Improve bone density

• Support hormonal health

• Reduce injury risk

Focus on good technique and controlled movement, not just intensity.

2. Warm Up Like You Mean It

A quick 2 minute jog doesn’t cut it anymore.

Your body needs:

• Mobility work

• Activation (especially glutes and core)

• Gradual increase in intensity

Think of your warm-up as injury prevention, not a box to tick.

3. Respect Recovery

Recovery is where the magic happens.

Make space for:

• Rest days

• Quality sleep

• Walking and low-impact movement

• Stretching or mobility work

If you’re constantly sore, tired, or tight, your body is asking for more recovery, not more punishment.

4. Add Variety to Your Training

Your body thrives on different types of movement:

• Strength

• Cardio (including intervals)

• Mobility

• Stability work

Doing the same workout on repeat is a fast track to overuse injuries.

5. Listen Early, Not Late

A niggle is a warning sign, not something to push through.

Address it early with:

• Reduced load or intensity

• Technique adjustments

• Targeted strengthening

• Professional support if needed

Ignoring it is what turns a niggle into an injury.

The Bigger Picture

Your body isn’t “breaking down”, it’s evolving.

Your 40's are an opportunity to:

• Train smarter

• Build real strength

• Support your hormones

• Create longevity in your fitness

  
  

Those niggles? They’re feedback.

And when you learn to listen, adjust, and support your body properly, you can feel stronger, more capable, and more energised than ever.
