You do not need to be super fit or super bendy to participate and enjoy the yoga. You also do not have to have done any yoga whatsoever. The classes will cater for beginners to advanced yogis.
The morning classes are slightly stronger and you may get a little sweaty but rest assured, Toni will provide options for all fitness levels and flexibility levels. If you do ever feel that the class is too tiring or too much for you, you can rest in childs pose until you are ready to join in again and you can always discuss anything with Toni, your yoga instructor. Listening to your body is the most important thing.
