Got stuck for about 3 weeks in my head and my weight loss plateaued. Then I heard this great music coming from another room in the gym and stuck my head in. There were all these women dancing up a storm. I couldn't resist, so I jumped right in. Tomorrow starts my third week and the weight is dropping off. I lost two pounds in the last week. More, my flexibility is incresing literally by leaps and bounds. I just have a little trouble with shaking my butt. That part is not really natural for a guy. So if you are stuck, try Zumba.
