Badminton always turns back and runs, and it is always in a hurry to stop. This amount of exercise is quite huge. The amount of table tennis exercise is moderate, because the scope of table tennis itself is relatively small and the competition time is relatively short.
Table tennis is a local muscle group sport, while badminton tends to exercise all over the body. Table tennis courts are also relatively cheap, less tense and less external constraints. But if you want to exercise, personally, swimming and jogging may be better!
