Plank is definitely one of the best teenage exercises out there!

Plank strengthens your core, and a strong core is important because you use it every day for everything, it helps keep your back healthy and strong, improves your posture, and more!

Healthy abs will help you infinitely in the present as well as later in life.

I consider plank the best core workout because you can multitask in plank?put a book on the floor and read to pass the time, put a phone there instead and you can watch music videos or YouTube!

Perfect for a busy teen!

Plus, you can mix it up in plank;

challenge yourself at your own pace by putting one arm up, inverting your plank, or going onto your elbows.
