Working your abs is not an easy job! Each of the abdominal muscles respond to training at a different rate, and there is another group of abdominal muscles just below those ‘6-pack’ muscles with fibers pointing in the opposite direction, which makes up your core. This is why no single exercise can attack the core and why it’s so gang hard to work them!
It’s funny to think that this 5-minute plank workout requires virtually no movement! However, you’ll feel the burn in the abs, chest, butt, lower back and core. To get the most out of this workout, engage your core abdominal muscles during each rep!
