Description
Plank Jack is a dynamic and cardiovascular core exercise performed by opening and closing the feet in a jumping jack motion while in a plank position. This movement works the abdominal muscles, shoulder stabilizers, hip muscles, and inner thigh muscles. Since it has both strength and conditioning training characteristics, it is frequently preferred in HIIT programs. Performing dynamic lower body movement while maintaining core stability improves coordination. It is much more effective than static plank movement in terms of calorie burning and accelerates metabolism. The difficulty level can be personalized by adjusting tempo from beginner to advanced level.
