Working the bar scene is definately good exercise. There’s a lot of standing, dancing, and of course the walking from one establishment to another. So clubbing is pretty good for your lower back.
Several people I work with helped create this video for a business partner who is marketing a new energy drink. Clubbing and energy drinks are great companions, especially if you can find a drink that tastes great while giving you the boost you need.  And the advice offered in this video is priceless.
