I'm 18 and I posted here a good while ago asking aboutwhat to do with hardly any time or money. I have since sorted my situation out to some extent and now have about 30 mins to an hour each day to train. I am still training using what I have at home as I still can't afford to go to a gym.

Question 1:
When is the best time to train and is my diet ok? I have been training roughly 15-30 mins before dinner. I am still only having 3 meals a day but have significantly upped my protein and carb intake by trying to eat plenty of bread, pasta, tuna and chicken. I am also eating more in general.

Question 2: What exercises should I be doing with what I have? I have dumbells and a barbell, both of which I can change the weight on. The weights are generally a bit too light for most lifts so I improvise using the old steel wheels off my Fiesta in conjunction with the weights which tops it up nicley. A couple of days ago i also tied some other dumbells and some squash bottles of water to the barbell to try some deadlifts.
I am looking to bulk up a bit. I dont want to be massive, I would just like to be a bit above average and be reasonable well toned by the end of the summer.

How many reps should I be doing of each of the exercises? Self explanitory, I want the best results as quickly as possible without killing myself.

Thanks in advance for any help.
