Here's Britney Spears showing us her workout regimen on video. She's gotten fit very quickly and she did this by working out with her trainer for four or five days a week.

This short one minute video gives us an inside peek into her beautiful home gym and how she works out there in front of an enormous mirror.

Spears started a video section on her website just a couple of weeks ago. Her staff have put about ten videos there including a few 'blasts from the past', from way back about 8 years ago.

This self-absorbed fitness workout is a cool and very interesting video and her soundtrack fits right in, check it out here;
