Kathleen Trotter shows you a cheeky way to firm up your core & let your innner child play a little at work.

Try sitting on a “sit-disc” – an air-filled device that looks like a whoopee cushion, but sneakily provides all the benefits of a ball. ($40 to $50, available at fitter1.com. Look for “active sitting.”). Sit on it for one hour. The goal is to keep the air evenly distributed throughout the cushion.Carrie Cockburn and Trish McAlaster/The Globe and Mail
