Dance routines and aerobic exercise is safe to continue as normal if you are experienced, although you may want to tone down the intensity level and make sure you do not exert yourself to the point of exhaustion, which could deprive your body of oxygen. However if you are a beginner I would advise low impact dance or aerobics, or even water aerobics.
Swimming and exercise in water is great. In water you weigh just a tenth of what you are out of the water. It is gentle on your joints but also allows you to boost your strength and flexibility.
Gym machines such as step, rowing and treadmills are also great to use during pregnancy, including beginners. You can adjust speed, inclines and tensions to a level of comfort for you starting slowly if you are a beginner. Make sure you stretch beforehand and take it slowly. During the 3rd trimester it is best to avoid jumping and fast running and be very careful to avoid falling over.
Jogging for the experienced runner is also fine and during pregnancy you can stick to it but you may want to consider limiting your distances and sticking to a more level terrain (or use a treadmill). If you were not a runner before pregnancy I would suggest you stick to walking for now. Bear in mind that loose ligaments and joints during pregnancy can make running harder on the knees and also make you more prone to injury, so make sure you do not over do it.
Kick boxing during pregnancy, now it takes a great deal of grace and speed, 2 things that are reduced during pregnancy. You may find you are not able to kick as high or move as quickly but if you are still comfortable getting exercise from kickboxing and you are not a novice it is fine to continue. Be careful to avoid movements that you have difficulty in doing or that cause you to strain, and remember not to over do it.
Outdoor sports such as cycling, skating, hiking and skiing are not to be taken up as your new sport especially as they test your balance but again if you are experienced (except skiing) in this area and are comfortable to continue it is fine. However high altitudes, slippery conditions (skiing) and rock climbing are not advisable. Be careful about safety; don't cycle in wet conditions, or windy and rocky paths and always wear a helmet. With skating as you get bigger your balance will become more challenging and then it is time to hang to your skates up for a while. Skiing is too dangerous as there is high risk of serious injuries, even if you are in the Olympics.
Last but definitely not least I will mention walking, which is great for everyone anywhere and everywhere. Start slow and build up to a brisk walk.
With all this exercise don't forget to drink, drink and drink some more, especially in the hot weather.
