What Is the Dead Bug Exercise?
The Dead Bug is a progression from Marching and is an excellent core exercise for all fitness levels. It focuses on core stabilization and abdominal control while requiring slightly more coordination than Marching.
The goal of the exercise is to keep the torso completely stable throughout the movement. Nothing on the mat should move except the arm and leg that are actively working. If you notice movement in your lower back, rib cage, or shoulder region, decrease the range of motion until you can maintain proper alignment and control.

Instructions
Please read both the ideal exercise instructions and the modifications before attempting the movement. If you have an injury, medical condition, or experience pain, it is strongly recommended that you consult your physician before beginning a new exercise program.
If you are cleared for exercise, begin with the modified versions and progress gradually as your strength and control improve. If you have any questions, please do not hesitate to contact me.

Ideal Exercise
- Lie on your back with your knees bent, feet flat on the floor, and arms reaching toward the ceiling.
- Brace your core and maintain abdominal engagement throughout the movement.
- Bring one leg at a time into a tabletop position.
- Slowly straighten one leg in front of you. The angle may range from 30 to 90 degrees depending on your stability and strength. Begin at 90 degrees and gradually progress lower as control improves.
- Simultaneously reach the opposite arm overhead.
- Hold the position for 3 to 5 seconds while maintaining a neutral spine.
- Return the arm and leg to the starting position.
- Repeat on the opposite side.
Modifications
If you feel any discomfort in your lower back, stop the exercise immediately.
- Increase the leg angle so the foot stays higher off the floor.
- Reduce the range of motion of the arm and leg.
- Perform only the leg movement or only the arm movement until stability improves.
- Focus on maintaining a neutral spine and avoiding movement in the pelvis or rib cage.
In general, a smaller range of motion is safer and more effective than sacrificing alignment for difficulty.
Variations and Progressions
- Lower the leg closer to the floor while maintaining spinal stability.
- Increase the hold time at the extended position.
- Hold very light weights in the hands (1–3 pounds maximum).
- Slow down the tempo to increase time under tension and core activation.
Common Mistakes
- Allowing the lower back to arch off the floor.
- Moving too quickly.
- Lowering the leg too far too soon.
- Losing abdominal engagement.
- Shrugging the shoulders during the arm reach.
