"10mins of cardio"? Is that a typo?
If your name is indicative that you're 30, make sure that you get 3 days of rest to repair stronger between weight training sessions (with a good high protein diet to build up muscle mass).
Never do weights if you're still sore from the last session.
The rest of the time, you can do cardio (aerobics)...surely more than "10mins"...you start using body fat after about 20 minutes so you can last longer. Allow at least one rest day/week.
You should start noticing toning and strength within 3 months. For muscle definition, that would depend on how much body fat you have to lose. The lowest your BFP (Body Fat Percentage) goes, the better you can see your muscles.
