Waist-Slimming Ab Moves.

This toning abs workout will slim down your waist size from the inside out.

If the only things you twist are jar lids, then you're missing a great chance to tone your belly. Twisting abdominal moves focus on your deepest core muscles, which will both strengthen and narrow your waist. Do these four exercises for women from California trainer Paul Check and get a whole new side view.
