Owner Linda Ibrahim said she couldn't wait for the high temperature exercise to come to the South Side.

She said: "It's intense and challenging but afterwards you feel so amazing that you can't wait to do it all again.

"I'm so excited to see it growing in Scotland.

"It's such a healing exercise and it's great seeing people overcoming injuries that they thought they would never be able to by doing Bikram yoga.

"We are going to run 18 classes a week, and we're open seven days a week.

"The classes are for people of all abilities, from complete beginners to experts as everyone is able to work to their own level."
