“The lunge is by far one of the most effective exercises you can do to tone and strengthen your lower body,” says Druxan. “It works a lot of muscles in just one move, including your quadriceps (front of your thighs), hamstrings (back of your thighs) and your gluteus maximus (your bottom).”
To try them yourself, hold onto the stroller and take really long strides while lowering your upper body down until your front thigh is almost parallel to the ground. Your front knee should go no farther then your toes. Lower slowly and squeeze your thighs and glutes to come back up. Repeat on the other leg and continue switching legs for three minutes.
Try incorporating three total lunge walk circuits each time you’re out with your baby to score a tighter lower body.
