The Biggest Loser 3 TV Show The Plank Exercise

I Love this exercise, as shown on The Biggest Loser Sept 27th show, Bob teaches his students how to do The Plank.

This is a great exercise especially for your back and stomach muscles (your core)

How to do it:
Lie face down with forearms resting on the floor.
Push of the floor one leg at a time onto your toes, resting on your forearms.
Keep your back flat, in a straight line.
Hold for 20-60 seconds and repeat for 3-5 reps.

Do this daily and you will increase your posture, your stomach & back muscles will get tighter and toned.
