00:00Want to know how healthy your heart really is?
00:02Forget fancy tests.
00:04Just run for 12 minutes and check this chart.
00:06It's called the Cooper Test, a simple fitness test created by a U.S. military doctor in 1968.
00:12You run, jog, or walk fast for 12 minutes.
00:15No stopping.
00:16Then check how far you went using any fitness app.
00:19This distance reveals your VO2 max, a key marker of heart health.
00:23The farther you go, the stronger your heart is for your age.
00:27Here's what average looks like.
00:29A man in his 30s should run 1.9K.
00:31A woman the same age, 1.7K.
00:34In your 50s, aim for 1.6K if you're male and 1.4K if you're female.
00:39Run farther than that, and you're doing excellent.
00:42Fall short?
00:43Time to step it up.
00:44Want even more insight?
00:46Push-ups and balance matter, too.
00:48Can you do 10 push-ups at 65?
00:49Or stand on one leg for 10 seconds?
00:53These could predict how long you'll live.
00:55Your body is talking.
00:56The real question is, are you listening?
