Another pinner said: This website is AMAZING. It is my workout bible, and best of all, its completely FREE. Tons of workout vids and plenty more to stave off ruts. Most of the routines are between 12-20 mins long and that's all you need.
You do five a day, moving them to the done cup. At the end of the week you move them all back into the workout cup and start over, this helps you get a varied workout. - GREAT idea. So many different ways you could go about this also.
