This is without a doubt one, if not thee worst "fitness" dvd ever made. The ab exercises are designed to build up the abs for a boxy mannish look while the pilates inspired leg work is not explained thoroughly. Nor does Anderson offer any decent modifications for new users. All her clients end up looking just like her-no hips, no bust, no form, no real waist definition. No thanks!
