Planks~~OMG!!!

Options
I started doing planks today and my abs are killing me, to say the least. They are probably one of the best core exercises that I could recommend to anyone. I am doing 30 second hold times for now but hope to work up to 60 second. These are one of the hardest toning exercises that can be done. If you watch The Biggest Loser you will see them doing them all the time. They are one of Bob's favorite "torture" techniques.
