Hi, I've never really stuck with a rotation but i'm thinking thats what i need right now. I have about 5-10lbs to lose and would like to get some really good definition. I can only workout mon-fri for no more than 1 hour. What do you suggest my rotation be? i was thinking of lifting mon, wed, friday and then doing cardio intervals for 30 mins and abs on tues and thurs but i'm not sure if this is enough cardio. what do you think?
