A bright, airy yoga centre on Lavender Hill, Union Station offers free tea before and after classes, plus water in reusable jars. Pregnancy classes take place in a cosy studio downstairs, where a friendly instructor will take you through breathing exercises and a series of dynamic movements to keep you strong and supple. The section focusing on the pelvic floor is particularly useful.
