Start on the ground on your hands and knees.
Keep your back flat, shoulders back, and neck straight to keep your core muscles tight and strong.
Slowly lift left arm forward while extending your right leg behind you, hold 2 seconds, then bring your left elbow into your right knee and repeat.
Perform all reps on one side before switching sides.
