Awesome Abs without Crunches: these moves work the transversus abdominis (deeper muscles that wrap around your trunk) as well as the obliques along your sides. Translation: a tinier waist, a flatter middle and sexy definition—fast!
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.
