Generally, I don't feel anything when dancing slimming and fitness dance. Only the stretched leg hurts a little, because I didn't warm up well. Next time, just run for 120 minutes and then dance the slimming fitness dance. Don't worry. Seriously, the effect of losing weight is not particularly good, but it can be used as a fitness jump. I actually love amy chan more. Quick effect, no time. Quite suitable for people who go to work.
