WHY: This exercise is the most challenging version of the dead bugs. Bringing out both arms and legs will increase the challenge on your abdominal muscles.
HOW: Start this exercise on your back in a 90/90 position of your knees and hips and your arms in front of you. Keep the small of your back pushed into the floor by activating your core. While maintaining core activation drop one leg and the opposite arm towards the floor alternating sides. The closer you drop the arms and legs towards the floor the more challenging this exercise will be.
FEEL: You should feel the abdominal muscles engaging while you perform this exercise.
