Being pregnant doesn't mean you're fragile or weak all of the sudden. If you've already been working out before your pregnancy, you can keep working out so long as your doctor says it's OK (and most do). As your baby and belly grow, though, you'll need to cut out some exercises and practices. The hormone called relaxin will begin to pump through your body, allowing your musculoskeletal system to loosen up and shift. This will affect your balance, strength and mobility. Below is a quick reference guide referring to exercises that are permissible during each trimester and movements you should absolutely avoid. Carry over the "don'ts" from one trimester to the next.

First, it's important to know the warning signs of pregnancy-related problems caused or irritated by exercise. The American Fitness and Professionals Associates group lists several symptoms, including vaginal bleeding, shortness of breath before exercising, dizziness, headaches, chest pain, calf pain or swelling, muscle weakness, decreased fetal movement or amniotic fluid leakage. If you are experiencing any of these symptoms, skip the workout, call your doctor, and together figure out what the next best step is. (via AFPA)
