3/4 Sit-Up vs Butt-Ups

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.

Begin a pushup position but with your elbows on the ground and resting on your forearms. Your arms should be bent at a 90 degree angle.

Arch your back slightly out rather than keeping your back completely straight.

Raise your glutes toward the ceiling, squeezing your abs tightly to close the distance between your ribcage and hips. The end result will be that you'll end up in a high bridge position. Exhale as you perform this portion of the movement.

Lower back down slowly to your starting position as you breathe in. Tip: Don't let your back sag downwards.

Repeat for the recommended amount of repetitions.
