Toning: 1–2 minutes
Stand with your feet hip-width apart, toes forward. Hold on to the stroller with your elbows bent, abs drawn in, shoulders back and down.
Keeping your weight over your heels, bend your knees into a squat until your thighs are as close to parallel to the ground as possible, leaning your torso forward at a 45-degree angle. Keep your knees over your ankles and straighten your arms, letting the stroller roll away from you.
