WEEKEND (Dec 8-9) MINI CHALLENGE

5 Sets of 60-Second PLANKS

The Plank is great for building strong abdominal muscles! If this is your first time, start off by holding your plank for 10 seconds. If you can continue holding your plank with good form, stay up the whole minute or as long as you can.

Here’s how to do them: http://exercise.about.com/od/abs/ss/abexercises_10.htm
