Let's get physical, physical! SpecialExercises is technically a fetish site, although it has one of the more unique spins on rigid discipline than your average whips and chains site.

The subs on this site are forced to do grueling exercises and workout routines. The instructors are generally female and guide their charges through a series of punishing exercise workouts, usually while the chicks are nude. I didn't know that jazzercise qualified as a fetish, but it's still hot.

The content is as straightforward as that. There's no intercourse involved – just subby babes getting naked and getting fit. I don't know if this qualifies as BDSM though. I could be narrowminded, but other than getting verbally ordered around, the action isn't any rougher than a YMCA workout. Still, there's something very sexy about watching naked babes work it for a harsh instructor and I'll take these workout sessions over Tae Bo any day.

Currently there are 155 episodes available with new material coming in every 16 days or so. Every episode comes with its own pics and vids as you would expect. The pics really don't do the action justice. Since a lot of the kink comes from the verbal abuse it's pretty hard to capture that with mute photos. These are still high-res pics, however, that ought to give you a good idea of what to expect in the vids.

The movies can all be downloaded and watched with excellent-looking Windows Media files (the older ones are good in quality). This is where the action is. Every episode has a harsh taskmaster who really puts his or her pupils through the ropes. They give them a verbal tongue lashing and the babes struggle to keep up with their demands.

There is also one bonus site called LesbianArmy. This is a fairly narrow niche and this site does a good job of tackling it, but it's expensive.
