MORE than 50 people attended a free Tai Chi session at Arrow Valley Park. Held every Tuesday at 1.30pm throughout the summer, the sessions offer residents the chance to enjoy gentle outdoor exercise in the park. Tai Chi can help improve balance, flexibility and strength while promoting relaxation and reducing stress. I can’t do physical exercise, but this I can do and I think it will help me. The free sessions are open to everyone, with no experience required.
