Tone Up Thursday: Plank Position

The Plank exercise is in arguably on of the best exercises for core strength.  If you haven't tried or don't know, here is a short video on the plank: https://www.youtube.com/watch?v=ASdvN_XEl_c I like this video because it will demonstrate the simplest, easiest form of plank but also how to progress to more difficult versions as you get stronger. The challenge today is to hold 1 minute of plank 3 times.  Take as much rest as you need and be very careful of your form.  Best to watch the video with a friend and then have them watch your form and correct you as necessary. It's great for the abs but also the back, hips, shoulders and chest. Accept the challenge?
