Book excerpt: Lisa Druxman, a certified personal trainer and fitness professional, knows one of the challenges new moms face: How do I get back into shape after giving birth? After Lisa gave birth to her first child, she developed exercises that she could do with her baby, using power walks, the stroller, and exercise tubing. Now she brings the proven techniques of Stroller Strides to moms everywhere, with a total f tness program for pre- and postnatal fitness and nutrition. In addition to stroller-based workouts, Lisa outlines front-pack carrier workouts and eating plans to combat post-baby weight gain, energy loss, and mood swings. LEAN MOMMY gives moms the ability to have it all: satisfying workouts, real results, and bonding time with baby.
