You're leaning forward, causing your front heel to rise.
Perfect Your Form
"When you lunge, keep your torso upright, and focus on moving it up and down, not backward and forward," says Rasmussen. This will keep your weight balanced evenly through your front foot, allowing you to press hard into the floor with your heel—and target more muscle.
"Drop your back knee straight down to the floor," says Boyle. Consider this a second strategy to help you remember that you should drop your torso down, not push it forward, as you do the exercise.
"To work your core harder, narrow your starting stance," says Gray Cook, M.S.P.T., the author of Athletic Body in Balance. The smaller the gap between your feet, the more your core has to work to stabilize your body. Your goal: Lunge so that it's almost like you're walking on a tightrope as you perform the exercise.
