Scientists still don’t fully understand
the relationship between exercise and
brain power. For the moment, people just
have to trust that exercise is helping them
to learn or remember. Scientific research
clearly shows, however, that three or
more workouts a week are good for you.
A study in the Journal of the American
Medical Association, for example, shows
that walking four to five miles (6.5 to 8 km)
an hour for 45 minutes five times a week
helps you live longer. S0 d0n’t be a couch
potato. Get out there and do something!
