ANN ARBOR, Mich., Dec. 31 (UPI) -- The secret to keeping to an exercise plan throughout the year is for fitness to become a routine rather than just another resolution, a U.S. expert advised.

Colleen Greene, wellness coordinator at the University of Michigan Health System's health promotion division, said exercise must become part of a long-term regular routine rather than be thought of as a short-term solution.

"The No. 1 New Year's resolution people have is to lose weight and it is really not that difficult," Greene said in a statement. "But many expect it to be done overnight and they lose their motivation when that doesn't happen."

To help stick with a new workout plan, Greene advised to:

-- Join a fitness center that is convenient -- someplace close, or offers child care.

-- Ask for personal attention, most gyms have personal trainers that can help navigate equipment and devise a fitness plan.

-- Get the OK from a doctor before beginning a new workout routine.

-- Aim to meet goals gradually.

-- Schedule exercise into your calendar and incorporate exercise into your daily routine.
