Stand with your back against the wall with your knees slightly bent, arms straight by your sides and palms facing the wall. (Carrie Cockburn/The Globe and Mail)
Pull your shoulder blades back, tuck your chin like you’re trying to give yourself a double chin and simultaneously push into the wall with your hands. Hold for five seconds. Release and repeat 10 times. Tip: Don’t let your lower back arch as you pull your shoulders back. (Carrie Cockburn/The Globe and Mail)
