Globe & Mail: How to work your glutes
Place your right foot on the ground in the middle of the door frame. Step your left foot backward and lower yourself into a lunge.
Place your finger tips on the frame to help you balance.Carrie Cockburn and Murat Yukselir/The Globe and Mail
Keep your right knee bent and your body low to the ground as you bring your left knee toward your chest (your left foot will come off the ground). The more stable your right leg and the lower you stay to the ground, the harder the exercise will be. Do 10 reps, then switch and repeat on the opposite leg.Carrie Cockburn and Murat Yukselir/The Globe and Mail
