I jumped half an hour square dance, weak, fatigue how to do?

According to my analysis of your physical fitness or not strenuous exercise is good, half an hour to dance into a weak, sweaty is the manifestation of physical weakness, you should start doing housework with children these low-motor things to start training themselves, sweeping, mopping, brushing dishes and cooking, is not better than dancing? And you can exercise and make your home clean in one fell swoop, don't you think?
