3/4 Sit-Up vs Decline Reverse Crunch

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.

Lie on your back on a decline bench and hold on to the top of the bench with both hands. Don't let your body slip down from this position.

Hold your legs parallel to the floor using your abs to hold them there while keeping your knees and feet together. Tip: Your legs should be fully extended with a slight bend on the knee. This will be your starting position.

While exhaling, move your legs towards the torso as you roll your pelvis backwards and you raise your hips off the bench. At the end of this movement your knees will be touching your chest.

Hold the contraction for a second and move your legs back to the starting position while inhaling.

Repeat for the recommended amount of repetitions.
