30日プランクチャレンジ

Why the 30-Day Plank Challenge? Plank exercises are some of the overall best exercises you can do to strengthen your entire core. And keep in mind, your core includes a whole lot more than just your abs.

A strong core is the foundation of a strong body. Think about it: A tree would fall if its trunk weren't solid and stable. Doing core work isn't just about your middle, either; having a strong core will make you a better runner, surfer, or yogi (or whatever activity you like to do) while improving your posture and balance. Working your core can also protect you from low-back pain — and yes, it’ll tone your abs, too.

One of the best core exercises out there is the plank. Not only will planking work wonders for your abs, glutes and hamstrings, you'll also find that it sharpens up your mental endurance too

We created an easy-to-follow 30-day plank challenge that will get you the benefits of a strong core in no time. Your goal will be to maintain proper form the entire time you are holding up your own body weight. This means you will keep your whole body in a straight line, from your heels to your hips to your shoulders.
