It's the time of year when Weight Watchers, Jenny Craig and Planet Fitness seem to have bought every available commercial minute to urge us to exercise. But who wants to brave the winter deep freeze to go the gym? An exercise room at home, on the other hand, leaves few excuses. These gyms are so nice they might actually entice you to stick to your workout.

Tell me all about it: This six-bedroom Villanova home makes working out inside — in a custom-built gym — almost as easy as working out outside, where there is a pool and a tennis court. Plus, we love the sleek, open plan inside and the palatial pavers for entertaining outside.

Tell me all about it: Arbor Hill is basically an athletic facility with several guest quarters attached. Not only is there an outdoor tennis court, an indoor tennis court and a multi-purpose gymnasium, but the property features private locker rooms with their own sauna. Plus there's room enough for a whole team with two renovated stone guest houses on the property.

Tell me all about it: This eight-bedroom home is named Skyview, and for good reason: The property is set on nearly seven acres and features views in every direction. If the elliptical isn't for you, this property features an indoor pool, as well as a private, indoor basketball court. If you're still sticking to your regimen by summer, there is also a multi-hole golf course and an outdoor pool.
