In this video, you will learn how to do a banded plank walk by Dr. Brian Damhoff.
This resistance band exercise targets core stability along with shoulder stability. It can be done easily at home with minimal space or at the gym. You can make it harder or easier. If you use a heavier resistance band, it will require more shoulder strength. If you walk further, it will require more core strength.
