Sarcopenia and how to stay strong

Ever noticed it’s harder to get up off the floor, lift something heavy, or even stand on one leg for long? You might be feeling the effects of sarcopenia—age-related muscle loss that tends to sneak up on us after 40.

From about age 30, we naturally lose 3–8% of our muscle mass every decade, and this speeds up as we hit our 40s and 50s. But here’s the good news: you can slow it down—and even reverse it—with the right approach.

Why should you care about sarcopenia?

Muscle isn’t just about strength—it affects:

  • Balance and coordination

  • Bone health

  • Energy and metabolism

  • Your ability to stay active and independent

Sarcopenia can lead to fatigue, weight gain, reduced mobility, and a greater risk of falls. But with the right training and support, you can continue to be – or become - strong, active, and confident.

What causes sarcopenia?

Sarcopenia isn’t just “getting old.” It’s influenced by:

  • Reduced physical activity

  • Lower protein intake

  • Hormonal changes

  • Chronic inflammation or illness

  • Sedentary lifestyle—which many of us fall into due to busy work/family schedules and then we simply don’t feel motivated to go back to it when our outside obligations reduce.

Signs you might be losing muscle

As with all things that affect our health, being aware of changes in ourselves is important and can help you catch an issue before it becomes a major problem.  Changes to be aware of when it comes to sarcopenia include:

  • Slower walking speed

  • Weaker grip strength

  • Trouble with daily tasks such carrying groceries, climbing stairs, or even getting up out of a chair

  • Feeling more tired or unsteady

  • Noticeable loss of muscle tone

If you’re nodding your head at any of these signs, it’s time to take action - and it’s never too late to start.

How to manage sarcopenia

You’ll be pleased to know that even if you do love working out, managing sarcopenia doesn’t mean hitting the gym for hours on end, benching big weights or overdosing on burpees. It’s about smart, consistent habits that build strength and support your overall health.

1. Prioritise strength training

Resistance training is the gold standard for rebuilding lost muscle. In my group training sessions (both online and in person), we focus on:

  • Functional strength (think: lifting, reaching, squatting, getting up off the floor)

  • Progressive resistance using bodyweight or weights

  • Safe, effective techniques that suit your body

2. Move daily

Movement matters—even on non-training days. Walking, stretching, or light cardio all help keep your muscles engaged and your joints mobile.  If you are struggling with walking, have a think about doing it in water.  Jumping in a pool and walking is fantastic for building strength thanks to the resistance from the water while minimising harmful impact.

3. Eat enough protein

Protein is crucial for muscle maintenance. Aim to include a good protein source at every meal—think lean meats, eggs, legumes, or dairy. Hydration and balanced nutrition matter too so drink lots of water and eat vegies of all colours!

4. Get expert guidance

Working with a qualified personal trainer (like me!) means:

  • You get a program designed for your current fitness level and injuries, not a one-size-fits-all plan

  • You train safely, with support and accountability

  • You stay consistent—and consistency builds results

  • And maybe the most important point is that my group sessions are loads of fun and filled with laughs!  If you are enjoying yourself, you are more likely to stick with it.
