How To Do Plank Jacks
Plank jacks are a core body exercise that strengthen all the muscles of the core and improve your stability. By “jacking” your feet out and in while trying to hold a steady plank, you are training all the muscles of the core to work better and stabilize you. In particular, you will learn how to draw in your transversus abdominus which is the key muscle for a flat belly. By using an unstable surface, more muscle fibers are recruited and used to keep your torso stable. If you learn how to do plank jacks you want to make sure to try and keep your torso as still as possible while your feet are doing the “jumping jack” action.
They may look easy, but don’t be fooled. Plank jacks and medicine ball plank jacks are both challenging exercises that will make you feel your abs and lower back the next day!

How To Do A Plank Jack
Here are the steps to performing plank jacks:
A) Begin in a plank position with your shoulders over your wrists, your feet together, and your body in a straight line.
B) Similar to the motion of a jumping jack, jump your feet wide keeping your buttocks down. Jump your feet back together.
Be sure to keep your lower abs pulled in very tightly as you jack your feet. If you do not pull them in, your body will bounce up and down and you will end up with a sore back and less results. Keep your belly super tight!

What Muscles Do Plank Jacks Work?
Benefits of Plank Jacks
There are many reasons you should incorporate plank jacks into your workouts. Here are just a few:
Plank jacks are, first and foremost, a core body exercise. This move gets your body to tighten and contract all of your core muscles while your feet are jumping out and in creating movement and instability through your trunk. Through the contraction of the core muscles you are able to keep your mid-section stable and strong during movement. It’s like a plank on steroids!
Stronger Upper Body
Plank jacks not only work your core, but you get a great challenge for your upper body as well. Your arm muscles will be contracted the entire time you are working and, much like the core, helping to stabilize you as your feet are jumping in and out. Plank jacks will target biceps, triceps and shoulder muscles for beautiful, sculpted arms.
Here’s a newsflash: you don’t need to be on your feet to get your heart rate up. Plank jacks are the perfect example of an upper body way to boost your heart rate and get a great cardio challenge. Try it and see if you aren’t breathing heavy in just 30 seconds or so. Results? Absolutely!
