Most of our regular weekly classes welcome beginners. There are one or two marked ‘intermediate’ or ‘not suitable for beginners’ so at the start of your practise those classes are not recommended. You will see those details when you ‘click’ on the class on the timetable and the full class details page is shown.
Perhaps a good starting place for you as a beginner, would be one of the Hatha Yoga classes which are spread throughout the week during the day and the evening. Some of those are specifically aimed at beginners, for those returning to yoga following a break, or who may be recovering from, or managing injuries or medical conditions. Those classes are clearly marked on the timetable.
