If you decide to hire a personal trainer, good communication will be critical to meeting your fitness goals, says Bridgit Kin-Charlton, owner of B-defined Innovative Personal Training & Wellness in Williamsburg, Va.
* Talk about specific goals. What do you want most: to lose a certain amount of weight, tone your arms, have a flatter stomach or maybe run a 5K in a certain amount of time? Let your trainer know.
* Relay your history. If you've tried to shape up before, share what worked for you and what didn't.
