At least 3 times a week.
It depends on how much extersice you do and the type of food you consume.
There is no standard limit to the amount of exercise someone should get each week. Listen to your body to determine if you are getting enough or too much exercise.

There is no set amount of exercise that people should do. If you are wondering how much exercise is too much for your body, it is important to talk with a doctor or a personal trainer. You should never work out to the point of pain, and it is definitely possible to get a great work out while treating your body with respect and not overworking yourself.
Exercise equipment is handy and easy to use. You should always read the manual for safety reason. Once built, you really don't need to maintain them that much.
