If you were active before your pregnancy, here's the good
news: there's no reason why you should stop exercising now. A moderate amount
of exercise is good for both you and your baby. Note, however, that certain
physical activities should be avoided.
Avoid the following: being too active during hot weather;
steam rooms, hot tubs and saunas; physical activities that call for you to lie
flat on your back, such as certain yoga poses; contact sports such as football
and boxing; and activities that make you jump or change direction quickly, such
as tennis or netball.
