Dead bug is an advanced core exercise that challenges the abdominal muscles in a supine position. It helps build core strength and trunk stability.
Begin lying on your back with both knees bent, feet flat on the floor and arms down by your sides. Draw in your abdominal muscles to stabilize your back as you slowly lift one leg at a time into a “table-top” position, so that your knees are directly over your hips and your knees are bent at a 90-degree angle. Your feet should be in the air, with shins parallel to the floor. Reach both arms straight up towards the ceiling, with palms facing each other.
Keep your spine flat against the floor as you extended the right leg and left arm straight, away from the starting position. Slowly return to the starting position, and repeat with the opposite arm and leg.
