The Dead Bug Exercise for Ab Muscles

Your core muscles, including your abs, play a vital role in every movement you make throughout your day. The focus of your core muscles is to keep your midsection aligned with your pelvis. Although this may not seem significant at first, proper body alignment ensures your body moves correctly, avoiding undue stress on your tendons, ligament, muscles and joints. The dead bug exercise focuses on strengthening the front portion of your core, mainly the rectus abdominis muscles.

  1. Strong Abdominal Muscle Benefits

    • The rectus abdominis occupies the front portion of your core. It counteracts the force applied on your spine by your erector spinae muscles running along your back. Balancing the strength of both your ab and back muscles ensures your spine remains in its correct position, possibly lessening your chances of dealing with lower-back pain. Increasing the strength of your abs requires performing exercises using the proper form. Improper form will change the dead bug from an ab-focused exercise to a possible injury-inducing nightmare.

    Abdominal Muscle Isolation

    • Since the dead bug targets your rectus abdominis muscle, you must isolate it before starting the exercise. To begin, find a suitable spot on your floor that feels comfortable. Lie on a yoga mat to increase your comfort, if needed. Place your arms by your sides, with your palms sitting flat on the floor, and your feet flat on the floor with a 12-inch-wide space between your heels and your glutes. Exhale as you try to move your belly button toward the floor. You will notice your abs tighten as you pull; this is the position to put your abs in when doing the dead bug.

    The Dead Bug

    • Lie on the floor with your arms by your sides, palms and feet flat on the floor. Move your feet until your heels sit roughly 12 inches past your glutes. Bend your elbow until you have a 90-degree angle between your upper and lower arms. Exhale while pulling your belly button toward your spine. Raise your left leg off the ground until your upper leg sits 90 degrees to your body, and your lower leg sits 90 degrees to your upper leg. At the same time, rotate your right arm -- at the shoulder -- until your upper arm sits perpendicular to the floor. Hold the position for a second or two and then lower both your arm and leg to the ground. Repeat the movement with your right leg and left arm. Perform the exercise for 10 to 15 reps.

    Increased Difficulty

    • When you master the single arm/leg dead bug movement, increase the difficulty of the exercise to place more strain on your ab muscles by moving both arms and legs together through each rep. During this variation, only allow your heels to tap the floor between reps. As you move through reps, keep moving to increase the work performed by the muscle.
