First Trimester Pregnancy Workout

Are you one of the lucky ones that is not sick during the first trimester?  If so, this is a great time to regularly exercise, and there are very few exercises you cannot do!  Even this early, I suggest staying away from anything that requires you to jump with two feet (jump squats, jumping rope with two legs at once), and at 12 weeks you should stop lying flat on your back for any exerices.  Other than that, the most important thing is to never feel strain in your abdomen (so no heavy lifting) and to just listen to your body. If you feel stretching in the abdomen, light-headed, or any signs of nausea, stop for a moment and then return to a less intense exercise.
