Since I am trying to do 10 minutes of stomach exercises everyday, I decided to try to do 20 minutes of stomach on the two days I do my strength workouts. It worked out pretty well, a little bit harder, obviously, but still workable.
My new tentative workout schedule:
Tuesday- Long Strength workout
Friday- Short Strength+ Running
The walking will have to turn into something else this winter, hopefully an exercise bike workout if I can find a stationary bike at a reasonable price!
