As we age, physical capacity becomes increasingly important.

Strength, mobility, balance and cardiorespiratory fitness all play a role in how well we move, perform and function over time. And maintaining them doesn’t require complicated training.

Squats help preserve lower-body strength and mobility. Push-ups develop upper-body strength. Dead hangs challenge grip and shoulder capacity. Stair work and step-ups combine strength, balance and cardiovascular demand. And walking remains one of the simplest ways to support long-term cardiovascular health.

The important part is continuing to train the qualities you want to keep. What you do now helps determine what your body is capable of later.

We’re heading to the CCR Medical Longevity Summit this week 🧬

And this year, our Founder, Owen Hutchins, will be taking to the stage to discuss something we’re passionate about at My Vital Metrics:

With more health measurements available than ever before, which ones actually matter?

Owen will be exploring the growing world of health and performance testing. What’s worth measuring, what can genuinely help move the needle, and where we should be focusing our attention.

📍 ExCeL London
📅 Thursday 1 October
⏰ 10:00–10:15
🎟️ Free to attend

The Medical Longevity Summit is open to all, so if you’re interested in the future of health, longevity and personalised testing, register on their website and come along and say hello! https://www.ccrlondon.com/medical-longevity-summit/

Your VO₂ max number is actually only one small part of what you can get from a VO₂ max test 👀

This test also shows you what fuel your body is using at different intensities, which can be really useful for working out where your Zone 2 actually sits and how efficiently you’re using fat as a fuel.

In this case, the runner thought their easy runs were in the 130s–140s, but their data showed their aerobic work was actually sitting much lower.

This is why I love looking at the full data rather than just giving someone a VO₂ max number.

Some of the things people say because they think they’re being healthy are actually red flags.

Here are three we hear all the time.

“I’ve stopped doing anything that gets me really out of breath now that I’m older.”
Red flag.

Your cardiorespiratory fitness naturally declines with age, which is exactly why it needs to be challenged. You don’t need to train like an athlete, but regularly getting your heart rate up and working at higher intensities can be an important part of maintaining health and fitness as you get older.

“I lost four kilograms in a week.”
Red flag.

That doesn’t mean you’ve lost four kilograms of body fat. Rapid changes on the scales are often driven by water, glycogen and gut contents, and if your calorie deficit is too aggressive, you can also start losing lean tissue. Faster weight loss is not automatically better weight loss.

And finally:

“I haven’t had a day off exercising this year.”
Red flag.

Training is the stimulus, but recovery is where adaptation happens. Your muscles, connective tissue and nervous system all need time to recover. More training isn’t always better training, and consistently ignoring recovery can eventually compromise performance and progress.

Health isn’t about pushing harder all the time.

It’s about giving your body the right stimulus, then giving it the opportunity to adapt.

Is all protein made equal? Not necessarily.

When evaluating protein, total intake is only part of the picture. Protein quality is also influenced by its essential amino acid profile, leucine content and digestibility.

Proteins are made from amino acids, nine of which are classified as essential amino acids (EAAs) because they cannot be synthesised by the body in sufficient quantities and therefore must be obtained through the diet.

For skeletal muscle, these EAAs are particularly important because they provide the substrate required for muscle protein synthesis (MPS).

Leucine plays a key regulatory role by helping activate the signalling pathways involved in MPS. However, leucine alone is not sufficient: the remaining essential amino acids must also be available to support the synthesis of new muscle protein.

This is why two foods containing the same number of grams of protein may not produce the same physiological response.

High-quality proteins generally provide:
• All nine essential amino acids in adequate proportions
• A relatively high leucine content
• High digestibility and amino acid availability

Whey, dairy, eggs, meat and fish typically perform strongly across these measures.
Plant proteins can also support muscle protein synthesis effectively, but individual sources may contain lower concentrations of certain EAAs, have a lower leucine density, or be less digestible. In practice, this can often be addressed by consuming a larger dose, combining complementary protein sources, or choosing higher-quality plant proteins such as soy.

So while total daily protein intake remains fundamental, the source of that protein also matters.
The key question is not simply “how many grams of protein am I eating?” but also “what amino acids does that protein provide, and how effectively can the body use them?”

How many carbs can your body actually use per hour?

Race-day fuelling is often built around generic recommendations. 60g, 90g, even 120g of carbohydrate per hour.

But your ability to absorb and use that carbohydrate is individual.

Our Fuelling Strategy Test, in partnership with ExoAnalytics, measures your exogenous carbohydrate oxidation during exercise.

You’ll complete a controlled 90-minute run or ride while consuming a specially prepared carbohydrate drink, with breath samples collected throughout the test. These are analysed to determine how effectively you’re using the carbohydrate you consume as fuel.

The result: a personalised fuelling strategy built around your physiology, helping you understand how much carbohydrate to take on during longer training sessions and races, without relying on trial and error.

Measure your fuel. Don’t guess it.
