I would always love new ideas. My schedule is like this:
I am doing the "Couch to 5K" running program 3 days a week.
I do cardio tennis for an hour two days a week.
I just started circuit weights two days a week for 45 minutes a pop (I'm thinking of adding another day of arms and core, but not legs till done with the running program).
Tennis season is starting soon and practices will be 1 1/2 hours weekly, plus matches.
When I get bored or if the weather is not cooperative, I change it up and get on the exercise bike, jack up the incline on my treadmill, or pull out a Pilates DVD with resistance bands.
Still trying to figure out how to roller blade in my very hilly neighborhood!
And now that you don't have to be perfect, you can be good.
