Britney Spears' gruesome training schedule.

Is the thought of exercising 6 hours a day enough to have you break out in sweat? Well, not BritBrit, apparently she does a normal 90-minute exercise routine every day, followed by 5 hours of dance training to get ready for her new North American tour. She's already been at it for 6 weeks and the tour kicks off June 16th in Sacramento. She's already in supershape, but come June 16th she's going to be ripped!
