Straight-Leg Sit-Up & Twist

How to: Straight-Leg Sit-Up & Twist

Primary Muscles Used:Obliques

Trainer:Kayla Itsines

1. Start by lying straight on your back on the floor, with both arms extended above your head. Place both hands behind your earlobes. Engage your abdominal muscles by drawing your belly button in towards your spine. This is your starting position.
2. Keeping your heels firmly planted on the floor, slowly lift your head, shoulder blades, and torso off of the floor. Ensure that it is your abdominals that initiate the movement, and that you do not use your arms to ‘swing’ your torso up.
3. As you sit up, extend your left arm and twist over the right side of your body, as shown. Slowly untwist and lower your torso back into starting position. Repeat using your right arm and twisting over the left side of your body. Continue alternating between left and right for the specified number of repetitions.
