At the beginning of the month, I decided to do a 30 day plank challenge. The goal is by the end of the month to hold a plank for 5 minutes. For those that aren't familiar with the plank, the basic plank exercise is a way to improve core strength and stability. You begin in a plank position with your forearms and toes on the floor while your torso is straight. The body in a straight line with no sagging. The abs are being held in as if they are waiting for a punch.
It's difficult to hold the position for a long time because you are really engaging your abs. The longest I've gone is three minutes non stop. I want to get to five minutes because I think it will further strengthen my core and tighten my abs. It won't be easy, but my hope is by the end of the challenge, I'll get to five minutes.
