You might be surprised to find that your tummy has tightened, your back pain has disappeared and more! Here are five reasons why you need to add plank into your life!

3. Flexibility

You'll find you have more mobility in your shoulders, collarbone and shoulder blades. This is great news for people who spend many hours working at a computer.

The plank will also lengthen and stretch out your hamstrings and even the arches of your feet and toes.

4. Improve Your Mood

Just like with any exercise, planking will enhance your overall mood. Because our bodies and minds are interconnected, we often internally interpret physical tension as mental stress.

By relaxing and softening various muscle groups around your shoulders and upper back, the plank provides a physical release that is also emotionally uplifting.

5. Improve Your Balance and Posture

Whether you're doing a forward plank, or one on the side, you'll enhance your ability to hone-in on your own center of gravity.

Planking requires balance, so engaging your core in plank builds muscle memory that you can rely on to stay balanced in your day-to-day living.

Give it a try! You may never need to go to the gym again!
