My office has a physical trainer that does a one hour interval workout twice a week. We rotate through stations constantly and each workout is different so there is no boredom, only griping. I really should do at least one more day of excercise, but it is hard to find motivation by myself most days. In previous years I was a medium distance runner (ran 5k and 10k races, finished around 50th percentile) which was great but hard to keep up during the winter (Chicago).
