Don't feel like exercising?

Researchers at the Univ of Pennsylvania say motivation to exercise waxes and wanes in any normal person.

Week to week, motivation can change a lot, says David Conroy, professor of kinesiology.

Conroy and his team took 33 college students and gauged their intentions to be active and their actual activity over a 10-week period.

The results, in the Feb issue of J of Sport and Exercise Psychology, were that motivation fluctuated a lot.

For some motivation was high on the weekend. For others, during the week.

The key, they thought, was to weave exercise into the day so motivation was not such a factor.

Maybe--what—selling the car? Wearing a pedometer all the time?
