Exercise on MFP

How to you track it if you use videos? When I did the 30 DS I tried to add it, but it's not on there. Neither is the new video I'm doing. I know I could put in what exercises I did for 30 DS, but the new video I'm doing is pretty much dancing lol.
I liked logging to exercise because it'd tell me how much calories I gained.

On my fitness pal?? When I did 30 day shred it was on there :s weird
