There's no one fitness regimen that works for everyone, and most doctors will tell you that anything that gets you moving is good for your health. We've seen some pretty weird workouts over the years, but "Fetish Fitness" has to be one of the most extreme.

The Sydney based classes, run by a dominatrix named Mistress Anna, have been going on since at least 2014, when SBS first discovered them, but they've resurfaced today, because you know we're all going to be trying to get our best bodies in 2018. The classes involve pretty basic circuit training, with a bunch of anything-but-basic fetish play thrown in. Think weighted squats with the weight attached to your penis. Pushups in baby diapers. Rowing machines with nipple clamps.

While all this may seem outlandish, Mistress Anna explained that combining fetish play with fitness is just another way to make her clients feel comfortable exercising and working out.

"I've taken the majority of exercises that you see in a normal circuit class and then kinkified them," she told SBS in 2014. "The clients come and see me not to just get fit and get off, I think it's because I really understand them and I allow them to be who they are."

In a recent interview with The Daily Mail, Mistress Anna said her courses are still going strong and getting bigger.

"I still have my original clients who have been with me since the beginning," she told The Mail. "Some of them just want to train in normal clothes but still want me to be stern with them," she said. "I love seeing people have a good time and keep fit."

One of Mistress Anna's clients, a married engineer named Ray who identifies as a submissive slave, told SBS that the workouts were both sexual gratification and self-improvement for him.

"It is a sexual turn on for sure," Ray said. "Mentally there's a certain excitement factor there, physically it's actually very hard work. You start to feel like you're out of your own body, sometimes you feel like you're floating on the ceiling. You don't feel pain like you normally would in normal circumstances."
