Framework 317 · in one look
How to use it

The fitness you build and keep over years protects the brain more than how hard any one programme is. Train steadily for decades; don't chase the hardest plan.

How sure we are

P Evidence: promising. Good studies, but small or few. Use it and keep checking.
