Senior exercisers aren't just active and athletic, they're Web-savvy. Masters Athlete magazine realizes that and recently launched GeezerJock.com.

The site allows members to create a profile with a unique Web address, post a blog, chat with other athletes, find training partners and post videos or photos of competitions. It's sort of like a MySpace for older adults who are involved in sports.

Members' interests range from typical activities such as running, swimming and golfing to more obscure activities such as fencing, shuffleboard and unicycling.

Who's a good candidate for the site? Masters Athlete magazine says it's anyone older than 30. But members seem to skew a bit older than that. Despite their age, these folks are considered active, energetic thrill-seekers. Not exactly geezers.
