Golf:  Normally no problems to continue, however balance can become a problem later in the pregnancy.

Horseback riding:  The risk of falling and too much jolting of the abdomen puts this into the unsafe category.

Climbing/Hiking:  Generally OK, but not at elevated heights of over 3000 Metres due to the reduced oxygen available.

Swimming:  Generally recommended.  Good exercise for the large and small muscle groups.  Good for heart conditioning.  Gentle on joints and ligaments.  Diving should be avoided.

Tennis:  If one already practices tennis, then a reduced paced game should be alright to continue.  Beware of change in balance.  Do not stretch the extra for that match winning ball.

Skiing, Snowboarding, etc.:  Not advised.  High risk of falling makes these activities dangerous.

Aerobics:  Generally recommended if the low-impact version is followed.  Water aerobics is a very good conditioning method to use during pregnancy.

Badminton:  Generally OK during the early stages of pregnancy.

Boxing, Taekwondo, Karate, Judo, etc.:  No

Football, Soccer, Basketball, Hockey, Rugby, etc.:  No

Sex:  Refer to this article

Yoga:  Gentle regimes are very good at toning strengthening the body.

Gymnastics, Trampolining, etc.:  Generally not recommended during pregnancy, especially not competitively.  High risk of falling.

Scuba diving:  No.  Very dangerous for the baby.

Fishing:  Fine to continue fishing, but this is not going to improve conditioning very much (unless there is a good long walk to get there).  Take plenty of water and food along if sitting on the river bank for hours on end.

Cycling:  Generally OK to continue when pregnant.  Check with your doctor if you have any pelvic problems.

Dancing:  Generally good exercise.  Take care not to fall or participate in too energetic/jerky a dance style.
