Lie face up with your arms overhead and your legs extended, resting on the floor.
Lift your hands and feet a few inches off of the floor into a hollow position, and keep your abs engaged by pulling your belly button into your spine and pressing your lower back into the floor.
Just like with a regular V-up, reach your arms forward toward your legs as you simultaneously split your legs into a straddle position and reach through your legs.
Lower your arms and legs toward the floor with control back into a hollow position to complete one rep.
