Know Where You Stand
You don’t notice your body changing day by day — until you finally measure it.
Four minutes. No clinic. Write the date next to it.

Test 1
How fast you walk across a room predicts more about your future than most things a doctor measures. A pooled study of 34,485 adults found the spread between slow and fast walkers at age 75 ran from 19% to 87% ten-year survival — same age, same sex, different pace.

tenths
Mark 13 feet with tape. Walk it at your normal everyday pace — not fast, not slow. Time it.
Test 2
Getting out of a chair without your hands is one of the first things to go — and one of the clearest signals that something has changed in lower body strength.

Test 3
This is the one nobody practices — and the one that decides whether a fall becomes a turning point. The sitting-rising test predicts more than mobility.

Test 4
Balance holds steady into your 50s and then drops fast. Not being able to hold 10 seconds on one leg was linked to 84% higher mortality risk in a 2022 study of 1,702 adults — independent of age, weight, and other health factors.

Test 5
Grip strength is a readout for whole-body strength — it shows up in study after study as a simple stand-in for overall capability. It’s the last of the five tests and the one that completes the picture.
With a dynamometer
No dynamometer? Try these alternatives
Towel hang: Roll a thick towel and hang from it over a pull-up bar or sturdy door frame. Time how long you can hold. Under 10 seconds = low grip; 10–30 seconds = moderate; 30+ seconds = good.
Grocery bag carry: Fill a bag to about 20 lbs. Carry it by the handles (not looped over your wrist) for 30 seconds. Can you hold it without the handles digging in and forcing you to put it down? Yes = functional grip. No = worth building.
Plate pinch:Pinch two weight plates or thick books of equal size between your thumb and four fingers. Hold for 30 seconds. If you can’t hold 10 lbs this way for 30 seconds, grip is below average.
