Pastas, rice, mmmmm plenty of carbs there. As for working out (doing weights) you shouldn't do 2 big muscles per day (from what I've heard), for example you should do chest and triceps. Make sure you warm up properly (get the blood running, stretches etc), and warm down.

For me personally, I find doing sets of 3 with reps of 6-10 (depending on muscle) with a weight that I'll struggle to get in the last few reps and therefore have to push myself. I also alternate my routine fortnightly by doing different muscles different days and sometimes even changing the exercise itself. Also try and find a partner, working out with someone is great, you both feed of each other and keep each other motivated.
