Keeping up your core strength can also aid in delivery and postpartum recovery. "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.
However, not all ab exercises are created equal when it comes to pre and postnatal strengthening. Some ab exercises can actually do more harm then good. A general rule to remember is to avoid and exercises done on your back after the first trimester, such as crunches, sit-ups, and any seated twisting motions.
Like I said earlier core strengthening during and post pregnancy is still very important. I have posted a video below in which I demonstrate 5 moves that are both safe and effective to do pre and postnatal. These ab exercises are also great fro someone who is new to fitness and looking to increase their core strength.
Do each move 10-15 times (unless otherwise stated) and do 3 sets of each move. Look to perform these exercises 3 times a week to continue to strengthen your core.
