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.
Dead Bug
Begin lying on your back with your hands extended above you toward the ceiling.
Bring your feet, knees, and hips up to 90 degrees.
Exhale hard to bring your ribcage down and flatten your back onto the floor, rotating your pelvis up and squeezing your glutes. Hold this position throughout the movement. This will be your starting position.
Initiate the exercise by extending one leg, straightening the knee and hip to bring the leg just above the ground.
Maintain the position of your lumbar and pelvis as you perform the movement, as your back is going to want to arch.
Stay tight and return the working leg to the starting position.
Repeat on the opposite side, alternating until the set is complete.
Verdict
Both exercises target the abdominals. 3/4 Sit-Up is a beginner exercise using bodyweight, while Dead Bug is beginner and uses bodyweight.
