Heres the schedule the program reccomends to do..

Monday- upperbody weight training
Tuesday - 20 min areobics solution
Wednesday - lower body weight training
Thursday - 20 minute aereobics solution
Friday - upper body weight training
Saturday - 20 minute aerobics solution
Sunday - free day

The next week it starts out with lower body weight training and so on. What I'm wondering about this is if it's ok to be doing the aerobics every other day like that. I would be either walking or using a stationary bike, won't that work out my lower body too much? Your supposed to let each muscle group rest for 48 hours right?
