Dancing square dance or square drill, in addition to the mood will be happy, the most important function, indeed will reduce weight.
I participated in square drill and square dancing six years ago, when I weighed 172 pounds. Now, 152 pounds.
The real weight loss of 20 pounds all by the square 'absorbed'. The square 'absorbed' my sweat. What is sweat? I think, sweat is fat, muscle "water", these excess "water", by my exercise "wring" out.
The key is to do the square drill or square dance in a serious way. I never ambiguous. Every move is strictly according to the computer protocol to do. Never fool myself, one is to afford to come out to do square drill or square dance time, two is in the square have a self 'image'. I'm just here to exercise and burn off the excess fat that my body has ingested over the course of the day.
I dropped the weight five years ago and have kept it off to this day at about 150 pounds and no longer dropping down. I think this is the efficacy of square exercise or square dancing. Don't ask for much specialization, just go for it seriously.
Now every day, I can move freely on my own legs and feet, and the quality of life has improved, which is not the result of the movement? Health is their own, no one can give. Persist and do it seriously. This is my experience.
