Boxer Rendall Munroe donned a yellow tutu to help raise money to educate young children in India.
He joined other members of Leicester's Bikram Yoga studio to take part in a Flashdance themed fund-raiser – which included 80s disco moves.
Students and teachers donned neon lycra, headbands and leg-warmers for the session on Friday evening.
Rendall, who has been training at the studio for two years, said: "When they said they were having a charity event, I decided I wanted to get involved. I had to get a costume and the tutu was just the thing.
"It was all in a good cause and we had a great time."
Money raised will help fund a commitment made by Bikram Yoga Leicester two years ago to fund the school fees of seven-year-olds Chandra and Manasa in Karnataka, India.
Owner Libby Nockles said: "The goal is to ensure the pair receive the best education possible in a nearby English-speaking school and, as of next year, the studio is also pledging to support Chandra and Manasa's two younger siblings."
The Flashdance theme was the brainchild of students Rob Hollway and Peter Barratt. The session also involved the 2012 British Yoga Champion, Faye Huiyu.
Teacher Rachel Blunt said: "It costs about £500 a year to educate each child."
