For many active women, pregnancy is a time to slow down--but only a bit. Alison Ferguson, 41, was super-active before and during her pregnancy with daughter Quinn, who's now almost 2. Ferguson took advantage of her oceanside life in Ventura, Calif., by surfing and playing sand volleyball until the end of her first trimester, as well as taking long beach walks and doing weight training and prenatal yoga. "But knowing there was a baby inside me kept me from doing stupid things, like going out when the waves were too big," Ferguson says. "Instead, after the first trimester, I kept a maintenance fitness program of weights, walking and yoga going."
