OK, I keep hearing about this. Might as well pin it:: Forget P90X...these under 20 min/day Online Workouts are NEW every day. No boredom, no plateaus. Try free at www.corecamper.com. Might have to try this..
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.
