Lower-Body Toner: Tush Tightener
Lying on your stomach with your baby in front of you, bend your legs so that they form a 90-degree angle and rest your chin on your hands in front of you. Then, keeping your feet flexed, slowly lift your knees off the floor, squeezing your legs together as you push your feet up toward the ceiling. Hold this position for 20 seconds (you can sing to your little one to help the time pass) and return to start. Repeat three to five times.
