Lie flat on your back. Extend your arms so they’re against the sides of your body with your palms pressing into the floor, or bend your elbows and place your palms under your butt.
Lift both legs toward the ceiling, engaging your abs and pressing your lower back into the ground.
Keeping your core strong, slowly lower your right leg down toward the ground until it is a few inches above. Then slowly scissor your legs, lifting your right leg back up as you lower your left leg down toward the ground.
