Performing the: A Step-by-Step Tutorial Plank Jack
Jump your feet out to the sides, similar to how you would do in a standing jumping jack, while maintaining the high plank position and keeping your upper body steady.
Quickly jump your feet back together, returning to your original plank position.
Repeat this motion of jumping your feet in and out for the desired amount of repetitions or time.
Make sure to keep your core engaged and your back straight throughout the exercise to avoid any strain on your lower back.
