This week we get a call from Jean, who says her desire to eat healthy and exercise comes on goes like the tide. Some days she's stern and on a healthy path, only finding herself willing to abandon the healthy lifestyle a weeks later. Fortunately, CrossFit star and trainer Stacey Griffith is with us to help answer Jean's question. Stacy is the author of "Two Turns from Zero: Pushing to Higher Fitness Goals--Converting Them to Life Strength."
