On my rest days I've been using the Wii Fit Plus. Last year this time I was really good at using the Wii Fit and would do 30 min every day of yoga, strength training and mostly aerobics. So far this year I've tried putting together some of the routines they have, but haven't found exactly what I want. I really wish it was more customizable. I'll admit when I do get on the Wii Fit Plus I'm often playing around with the new stuff on Training Plus, but most of that isn't very aerobic...but they are fun.
I need to get myself organized and figure out a good routine...or a few good routines...that will help me feel myself pushed and help me see results.
