In her new video Playboy's Yoga with Sara Jean Underwood, former Playmate and Girl Next Door Sara Jean Underwood demonstrates how she stays so svelte- with a rigorous routine of yoga.

This week we've got a very special one-handed workout for all you fetish fans out there!
The smiley, friendly hosts of most workout videos leave you cold? Prefer the aggressive affections of a professional dominatrix? Long for a blonde woman in a sexy nurse's outfit to scream RELAX! YOU'RE NOT RELAXING HARD ENOUGH! at you while you do yoga? Then S&M- Sweat and Muscle- aka The Dominatrix Workout- is for you, fella.
Produced in 1999, this video is the product of three blonde, athletic, New York based dominatrices- Mistress Desdemona, Mistress Jane, and Mistress Delilah- who, according to the intro to the video, are on a mission to "shape up this flabby city" with their special brand of fetishwear-clad cruelty. Skin Central thinks that ALL workouts are pretty cruel, so the addition of whips and chains is just icing on the kinky cake- if you're into that sort of thing, of course.
The box declares this to be merely volume 1 of a series of sinister shape-up routines, but considering The Dominatrix Workout is only available as an out-of-print VHS, Skin Central can only assume those dreams were crushed like a lipstick-coated cigarette butt under a spike heeled boot.
Whip that body into shape (literally) after the jump!

3-D Movies are mounting a comeback. Again. Be still, my bleeding eyes. Again.
At age 7, I stumbled upon the famous photograph of a movie theater audience staring up, enraptured, at Bwana Devil (1953) through paper eyeglasses with colored lenses.
Some nearby authority figure explained to me that those people were watching a 3-D movie, and those glasses enabled the images to jump right off the screen.
The immediate, flawlessly logical question I blurted out then was: “So why isn’t every movie in 3-D?” Nobody could explain it to me.
Seven was also the age when I happened up Pops McBeardo’s Playboy stashed in the bathroom hamper, so my unspoken query was: “And why isn’t Playboy in 3-D? And what about dirty movies?” The answers would come. As would I.
The New York Post reports that a number of clothing-optional establishments have cropped up around Gotham, where customers can (among other activities) eat, practice yoga, and enjoy stand-up (and potentially stand-out) comedians.
All this puts us in the mind of our favorite nude-in-public movie scenes, which include Monique Gabrielle in Amazon Women on the Moon, Isabella Rossellini in Blue Velvet, and literally hundreds of college hotties in American Pie Presents: The Naked Mile.
