Do 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. Perfect your plank (or learn to hold one for the first time) to tone your middle and boost your balance and posture in just four weeks. 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 ab 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 ab 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. The Plank Challenge is suitable for both men and women of any ages. No equipment or special type of machinery needed, just your body. The Plank is a form of bodyweight workout that will never go away, because it's so powerful and requires a small amount of time on your part. Plank helps you to achieve substantial results in a very short span of time. In our case, just 1 month of training. Most times the simplest exercise move results in the greatest gains for your fitness demands and plank falls into that category. Plank is good for sculpting your core, but not only that, it works your butt and hamstrings as well. This 30 day plank challenge is perfect for those of you who want to get a smaller waist and sexy flat tummy.
