I am doing Fi from Zelda Skyward Sword. My husband wanted to do Link and when I was watching him play I felt I had to do Fi. She has such cool and complicated costume. (still doing research on how to do her mask and hair.)
I have joined weight watchers, and starting to move more. I have been doing yoga, cardio ball, walking, belly dancing, WII fit, even some DDR. I will doing nearly anything so I don't get bored. If I get bored I don't work out I noticed. I have even started to bounce on my cardio ball while playing video games.
I have just motivated myself and have told myself the only person it hurts if I don't work out and eat right is me. Honestly my husband didn't mind me gaining weight since my chest gets bigger in the process. (silly boys)
