If you need a crowd to motivate you to work out, join the Celebrity Fitness-hosted party at Sunway Pyramid. They’ll be celebrating all things BOSU – that’s a fitness training device that looks like a stability ball cut in half. BOSU creator David Weck will be on hand to lead participants through BOSU Yoga, BOSU Pilates and BOSU Functional. The entrance fee includes a limited edition pink BOSU, as well as a goody bag worth RM300, and a chance to win a mystery prize worth RM500. Proceeds from registration will be channelled towards the Breast Cancer Wellness Association. Registration closes Sep 23.
