If you’re referring to the popular “5 things” aging checklist, these are useful functional markers, not a medical test. Being able to do them independently suggests you’re maintaining useful strength, mobility, and balance.
5 encouraging signs of functional strength
Get up from a chair without using your hands
This requires leg and hip strength and is closely related to everyday mobility.
Walk briskly for several minutes without needing to stop
This gives a rough indication of walking capacity and endurance.
Climb a flight of stairs independently
Stairs challenge leg strength, balance, coordination, and cardiovascular fitness.
Get down to the floor and back up safely
This requires a combination of lower-body strength, flexibility, balance, and coordination.
Carry ordinary household items independently
Carrying groceries, laundry, or a moderately weighted bag involves grip, arm, trunk, and leg strength.
The important part
Don’t treat these as a pass/fail test or as proof that someone is “healthy for their age.” Two people of the same age can have very different abilities, and medical conditions can affect performance.
If you want to maintain independence as you get older, strength training, balance exercises, regular walking/aerobic activity, adequate protein and good nutrition are generally much more meaningful than any single viral fitness test.
And if you suddenly lose the ability to do something you previously could, particularly because of weakness, dizziness, pain, or shortness of breath, that’s a reason to seek medical advice rather than simply assuming it’s normal aging.
