Strengthen Your Core

"Your abdominals and your entire core, including your pelvic floor, should be strengthened throughout pregnancy, and doing so will help not only during pregnancy, but also aid in labor and delivery - and recovery," says Sue Fleming, a certified fitness instructor. Fleming is also founder of Buff Fitness.com and creator of the video Buff Moms-To-Be.
