Add workout (not found)

Hello,

I have been entering my shoulder workouts in the general section as a comment because I can not find  a match for they type of workout I am doing.  Probably because it's not really an official exercise. 

To get a better idea what I am doing, this is the link:

Anyway, what would be your suggestion on the exercise pick list for this type of activity?

Thanks in advance,

Mark
