Have you ever heard about Plank? Plank is the isometric exercise for the abdominal muscles. The plank (also called a front hold, hover, or abdominal bridge)is an isometric core strength exercise that involves maintaining a difficult position for extended periods of time. The most common plank is the front plank which is held in a push-up position with the body's weight borne on forearms, elbows, and toes. Many variations exist such as the side plank and the reverse plank. The plank is commonly practiced in pilates and yoga, and by those training for boxing and other sports. The plank strengthens the abdominals, back, and shoulders. The current world record for the plank position is 4 hours, 1 minute in 2014. And mine is about 46s, what about you?  plank.GIF |
