Exercise to most of us usually means getting sweaty, but what about some exercise which helps you to relax, keep focused and re- energise? Tutors from London Lishi Arts will be holding free Tai Chi classes in the Edmond J Safra Fountain Court at Somerset House in May and June. All classes are suitable for beginners as well as those with experience. Turn up as you are but loose clothing and light footwear are recommended. Bring your own good karma.
