What are some good fitness tips for pregnancy?

Aerobic exercises: Aerobic exercises are great for pregnancy -- walking, stair-machine, recumbent or upright bicycle, swimming, low-impact aerobics. Clinical studies have also shown women who exercise have fewer problems with excessive weight gain during their pregnancies and also easier labors!

Low-impact aerobic: National guidelines recommend that healthy pregnant women get 150 minutes per week of moderate-intensity aerobic physical activity like walking. If you've done vigorous activity before pregnancy like running it's probably ok to continue, but check with your health care provider first.
