If you feel like you're from Idaho and need some help, we've got some tips.
First, get motivated.
One way is to have a goal.

"I have a client that wants to lose 10 pounds, I have another one who wants to lose 10 pounds, so we see who can do it first and the loser takes the winner to dinner or something fun like that," said Marshall Roy, a trainer at Equinox.

David Bishop found the elliptical machine.
"I can't run because my knees are kind of bad, and it's a better option for people with bad knees," Bishop said.
Try getting a gadget.
