Looking for fitness related video links for Twitter posts

We are looking for an assortment of fitness, workouts, exercise videos to post links from our Twitter page. The videos should be unique, short (under 4 minutes) and catch the audience's eye! Examples include someone doing extreme pushups, a basketball player jumping extremely high, or a funny mishap at the gym. Videos should be of the "home made" variety and not used for directing to competing sites. Videos can not be too common, or be part of a major media company like ESPN.com. Although some will be considered, like from general news media sites. Video restrictions will be explained later. Please bid on the number of video links and amount. Thank you!
