These Are the 4 Bodyweight Ab Exercises Kayla Itsines Wants You to Do For a Stronger Core

If you're more advanced, Kayla said to do this move holding a dumbbell overhead.

• Lie on your back and reach your arms behind you, pointing your legs toward the ceiling.
• Swing your arms toward the ceiling; as you do, lift your head and shoulder off the ground and touch your toes, while lifting your pelvis slightly off ground so your toes move toward your fingers. If your neck tires, place one hand behind your head.
