Who knew the old ‘putting a whoopee cushion on a co-workers chair’ routine could actually help strengthen their core and posture?
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
After an hour, take the sit-disc off your chair. Challenge yourself to recreate the feeling of sitting up straight and balancing without the aid of the disc.Carrie Cockburn and Trish McAlaster/The Globe and Mail
