aaaaand #pop! How long did it take you (or your wife) to pop? #14weeks for me this time. People are finally comfortable talking to me about being pregnant without wondering if I'm just fat. Lol

The American Congress of Obstetricians and Gynecologists lists several benefits of exercise during pregnancy, including improved mood, reduced swelling and possible avoidance of gestational diabetes. The group recommends walking, swimming and cycling as good options. The recommended weight gain for a normal-weight person during pregnancy is 25 to 35 pounds.

It \"was never about body image or body fat,\" Kieser said. \"For me it was just about eating to fuel me and my pregnancy best. I wanted to have energy. Eating highly processed crap all day just made me tired and lethargic.\"

Her book, PregFit, claims she had a pain-free birth. It also claims being PregFit is the cure to morning sickness.

But not everyone believes a fit pregnancy can do what Kieser claims. One criticism cited the 50-hour labor of a yoga instructor; other women who claimed not to be fit at all said they too had fast labors and easy childbirth.

Kieser said she hopes \"mums see there is an alternative way. I didn't want to be the tired, sore, exhausted mother any more. I wanted to experience this pregnancy to its absolute fullest potential. I wanted to be the best vessel for my baby to grow in.\"
