💪 Strength Might Be the Most Important Health Marker You’re Not Measuring

What if a simple strength test could tell you more about your long-term health than your step count… or even your running pace?

A major review published in the British Journal of Sports Medicine analysed over 150 studies (with 94 included in meta-analysis) looking at whether simple strength tests can predict future health outcomes.

🔍 The Big Idea

Across a large body of research, one consistent finding emerged:

👉 Higher strength levels are strongly associated with better long-term health outcomes.

Importantly, this is mostly observational research — so strength is best understood as a powerful marker of overall health, resilience, and function, rather than a single direct cause of these outcomes.

What it does give us is something very useful clinically:

👉 A simple, measurable window into how your body is coping with load, ageing, and activity demands.

📊 The Two Tests That Stand Out

Two very simple tests were repeatedly shown to be useful:

✔️ Grip strength

✔️ 5x sit-to-stand test (chair rises)

Better performance on these tests has been associated with lower risk of:

• Cardiovascular disease

• Type 2 diabetes

• Functional decline and disability

• Musculoskeletal problems

• Reduced independence with ageing

• Cognitive decline and poorer mental health outcomes

👉 In simple terms: these tests reflect overall physical robustness.

🧪 How to Test This Yourself

You don’t need a gym. These are quick, repeatable checks.

1️⃣ Sit-to-Stand Test (home version)

• Sit on a standard chair

• Arms crossed over chest

• Stand up and sit down 5 times as quickly as possible

• Time the total

👉 Faster time = better lower limb strength and functional capacity

here's Allison being put to the test!

2️⃣ Grip Strength (clinic-based)

• Use a hand dynamometer

• Squeeze maximally for 3–5 seconds

• Test both hands

• Record best score

👉 We track this over time as a marker of overall strength and recovery

We measured each of us in the clinic 

📈 What’s “Normal”? (Practical Benchmarks)

These are general reference ranges for adults. They vary with age, training background, injury history, and body size — but they are useful for self-checking and tracking change over time.

🪑 Sit-to-Stand (5 reps)

Time to complete 5 controlled stands

• 🟢 Good / strong baseline: < 10 seconds

• 🟡 Average / room to improve: 10–15 seconds

• 🔴 Below expected functional level: > 15 seconds

👉 Most healthy, active adults tend to sit in the green to mid-amber range.

🤝 Grip Strength

Men

• 🟢 Strong: 40+ kg

• 🟡 Average: 30–39 kg

• 🔴 Low: < 30 kg

Women

• 🟢 Strong: 30+ kg

• 🟡 Average: 20–29 kg

• 🔴 Low: < 20 kg

👉 Grip strength is one of the most widely studied “general health markers” in musculoskeletal and ageing research.

🧭 How to Interpret Your Results

Think of this less as a pass/fail test, and more as a snapshot of current capacity:

• 🟢 Mostly green → solid strength base and resilience

• 🟡 Mix of green/amber → good foundation with clear room to build

• 🔴 Any reds → opportunity to improve capacity (and usually very trainable)

👉 The most important signal is change over time, not a single score.

📈 What the Research Actually Means

This doesn’t mean strength is the only thing that matters.

But it does suggest:

👉 Strength reflects how well your body is functioning as a system.

It links to:

• Muscle and tendon capacity

• Nervous system efficiency

• Balance and coordination

• Ability to tolerate load (work, sport, daily life)

And importantly:

👉 Small improvements in strength are associated with meaningful improvements in long-term health outcomes.

🧭 Why This Matters Clinically

This fits strongly with what we see every day in clinic.

We’re increasingly focused on:

• baseline strength markers

• functional capacity (what you can actually do)

• tracking improvement over time

Because:

👉 Pain levels alone don’t tell us enough
👉 Capacity tells us much more about long-term health and resilience

🏃‍♂️ Simple Self-Check

A quick way to reflect on your current capacity:

• How easy are stairs?

• Can you rise from a chair without effort?

• Can you carry groceries comfortably?

• Do you feel strong in day-to-day movements?

👉 If these feel harder than expected, it’s often a sign that strength and capacity could be improved.

🏥 How We Use This in Clinic

We now routinely use simple strength measures as part of assessment and rehab, to:

• identify early strength deficits

• guide targeted exercise prescription

• track objective progress over time

• support return-to-sport and long-term health goals

🏁 Bottom Line

👉 Strength is one of the most useful and under-measured health markers we have
👉 It reflects how well your body is functioning and coping with load
👉 And importantly — it is highly trainable at almost any age
