Exercise is important, but exercise classes are expensive. Lucky for Sydneysiders, there are plenty of free and by-donation classes floating around if you know where to look. Potts Point's Reg Murphy Community Centre offers one of them — a free pilates class held every Wednesday from 10–11am. And they're running from February 14 all the way through December 19 this year. That gives you plenty of chances to join in or to make a weekly thing of it.
Pilates is known to strengthen muscles, improve flexibility and posture and increase mental awareness. Apart from the free bit, the one-hour classes — organised by the City of Sydney — are also open to all levels and ages. Mats are provided as well, though you'll have to BYO towel and water. Since it won't cost you a dime, there's really no draw-back to this one.
