Performing the: A Step-by-Step Tutorial Twist Sit-up
Place your hands gently behind your head, making sure not to pull on your neck.
Engage your core and lift your upper body towards your knees, like a regular sit-up.
As you lift, twist your torso to the right, bringing your left elbow towards your right knee.
Slowly lower yourself back down to the starting position and repeat the movement, this time twisting to the left, bringing your right elbow towards your left knee.
