Your leg strength predicts your brain power.
A 10-year study of twins found that leg power strongly predicted cognitive aging. The twin with stronger legs kept a sharper brain, better memory, and fewer age-related changes.
And here’s why: when you use your legs, you boost blood flow to your brain and increase the proteins that help your brain stay healthy. Even moderate movement like walking, stairs, light exercise, raises BDNF, brain-derived neurotrophic factor, which keeps your mind sharp.
So if every step you take is brain maintenance, why don’t you take the stairs today? Or walk an extra block? Your mind is worth it.
