(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.)
Thighs that don't rub together when you walk. Plus the pleasure of being called a tight ass. Just two of the reasons you might want to consider trying this lower-body workout from Stone, inspired by her Extreme Bootcamp! app.
