Which celebrity trainer will get you the best results?

When it comes to getting in shape, raise your hand if you've pined for a celebrity trainer of your very own? While you might not be able to swing private sessions, the top trainers all have websites and DVDs to help guide you to a sculpted, screen-ready body—that is, if you've got the time, discipline and motivation.

We asked Alycia Spadafora, a Toronto-based personal trainer and yoga teacher, to try out the workouts of the top 3 celeb trainers—Tracy Anderson, Anna Kaiser and Jillian Michaels—and report back on their methods and results.
