Performing the: A Step-by-Step Tutorial Weighted Dead Bug
Bend your knees to a 90-degree angle and lift your feet off the ground, so your thighs are perpendicular to the floor; this is your starting position.
Slowly extend your right arm and left leg, stretching them out and lowering them towards the ground, while keeping your other arm and leg in the starting position.
Pause for a moment when your arm and leg are just above the ground, then slowly bring them back to the starting position.
Repeat the same movement with your left arm and right leg, and continue alternating sides for the desired number of repetitions.
