Instructions
3/4 Sit-Up
Lie down on the floor and secure your feet. Your legs should be bent at the knees.
Place your hands behind or to the side of your head. You will begin with your back on the ground. This will be your starting position.
Flex your hips and spine to raise your torso toward your knees.
At the top of the contraction your torso should be perpendicular to the ground. Reverse the motion, going only ¾ of the way down.
Repeat for the recommended amount of repetitions.
Flat Bench Lying Leg Raise
Lie with your back flat on a bench and your legs extended in front of you off the end.
Place your hands either under your glutes with your palms down or by the sides holding on to the bench. This will be your starting position.
As you keep your legs extended, straight as possible with your knees slightly bent but locked raise your legs until they make a 90-degree angle with the floor. Exhale as you perform this portion of the movement and hold the contraction at the top for a second.
Now, as you inhale, slowly lower your legs back down to the starting position.
