Target your booty, inner thighs, and abs with this multi-tasking move.
Get on your hands and knees and then bend your elbows to the floor directly below your shoulders, palms facing down. Point your left foot and curl your left heel in towards your body. Engage your lower abs as you cross your left knee behind your right leg (touching the back of your right thigh).
Next, turn your left knee out to the side as you lift your leg up above your hip, keeping your knee bent as you raise it. Pull your left knee back into your crossed position, squeezing your inner thighs together as you return your leg to start. Be sure to press down with your forearms and keep your abs braced in tight so your body doesn't shift to the side as you lift and lower your leg. Repeat 20 times with the left leg, 20 with the right.
