This resolution may be good, but "it's a great bar for most people to achieve," said Melinda M. Manore, PhD, RD, professor of nutrition and fitness at University of Oregon. If your goal is too much, you'll have trouble getting caught, and you'll be patient, she said.

Repair: Split on two or two regions and meet with a risk-losser – a friend, a relative, or a personal trainer – that will make you stay in the program. "It's easy to walk every day at 6:00 am if you know a friend is waiting for you," said Manore.
