Jack Knife Sit Up
Step 1
Lie on your back on a yoga mat. Extend both legs and engage your abdominal muscles by drawing your belly button in towards your spine. This is your starting position.
Step 2
Inhale. Exhale. While keeping your legs extended, slowly raise your legs upwards until they form a 90-degree angle with your hips. At the same time, bring your arms forward and upward towards your feet, slowly lifting your head, shoulder blades and torso off the mat.
Step 3
Inhale. Slowly lower your arms and legs to return to the starting position, but without lowering your feet to the floor. Repeat for the specified number of repetitions.
