Just be aware of your change in balance and how it affects rapid movement. If you jog, you probably can continue as long as you feel comfortable doing it. Avoid becoming overheated and stop if you feel uncomfortable or unusually tired. Remember to drink plenty of water. If you are a swimmer, you can continue to swim.
Swimming is an excellent form of exercise.
The water supports your weight while you tone and strengthen many different muscles. Scuba diving is not advised. Golf and bowling. Both of these sports are good forms of recreation. You will just have to adjust to your enlarged abdomen.
