Marin is an adult yoga woman teacher. You can tell by her body shape, she is very muscular and slim. Marin teaches a very unusual type of yoga. All the students who have completed the course say that her methods are effective but very specific. The reason is that her methods are based on humiliating women as much as possible. All the students who have graduated say that Sam constantly insulted and humiliated them, and they all went to psychologists to recover their mental state. In addition to verbal abuse, all of her exercises are as humiliating as possible, and she forces her students to wear whatever she wants. Another downside is her smell; she sweats profusely and stinks, and her students say they've never seen her bathe. If you're wondering why they don't just leave if she's so cruel, Sam's classes are free, but you sign a contract that requires you to complete a year-long course of her exercises, or you'll be required to pay her \$50,000.
