Muscle Strength Habit Score
Muscle strength and mass decline with age, and can be measured with tests like grip strength or timed chair stands. This page does not estimate a "muscle age". It counts strength habits and everyday tasks against NHS activity guidance.
Before you start
Method : Muscle Strength Habit Score — a custom points score written by this site. Each answer adds or subtracts the points shown in the Methodology table below.
Validation : Unvalidated. The points have never been tested against any laboratory measurement or health outcome, and the result is not an age.
Review : not reviewed by a qualified clinician. Educational only — not a diagnosis or a medical test.
Sudden weakness, especially on one side of the body, can be a stroke — call emergency services.

Methodology & assumptions
Your score is the sum of the points below. The weights are our own judgement. The old version added made-up years for self-rated grip, push-ups, muscle mass and body fat, scored men and women differently and gave a "muscle age". Self-ratings without measurements and age norms can't produce an age, so it was removed.
| Factor | Answer | Points |
|---|---|---|
| Muscle-strengthening activity (weights, bodyweight, heavy gardening) | 2+ days a week | 0 |
| 1 day a week | +1 | |
| Rarely or never | +2 | |
| Standing up from a chair without using your arms | Easy | 0 |
| Some effort | +1 | |
| Need my arms | +2 | |
| Climbing a flight of stairs | Easy | 0 |
| Need a rest or the rail | +1 | |
| Very difficult | +2 | |
| Moderate activity per week | 150+ minutes | 0 |
| Under 150 minutes | +1 | |
| Little or none | +2 | |
| Protein foods (meat, fish, eggs, dairy, beans, tofu) | Most meals | 0 |
| Once a day | 0 | |
| Rarely | +1 |
Worked examples
Rarely strength trains, needs arms to stand, stairs very difficult, little activity, rarely eats protein foods: 2 + 2 + 2 + 2 + 1 = +9 points.
Strength trains 2+ days, stands and climbs easily, 150+ minutes, protein most meals: 0 points.
Understanding your result
This counts habits and tasks you reported. It is not a measured strength test and not an age. Health-agency guidance linked below is general and based on populations, not on this score.
