I follow a blog (http://bendoeslife.tumblr.com). The guy held plank position for more than 2 minutes yesterday. I thought I'd give it a try. I have a long way to go. Before I started, I told myself I'd make it more than 30 seconds. It's a good thing I had a goal in mind--I'd have stopped after 20 second. I thought I was going to puke. My competitive side demands I add this to my regimen so I can beat this so I can beat this guy.
