Q: How do u get ur chest shoulders and back really bulky in the matter of 2 months

A: You can't do too much in just 2 months, though you can certainly start making progress. If you're lean now, you need to start bulking -- overeating to gain weight and lifting heavy at the same time. Your weight gain should be pretty slow (no more than 1 pound per week and ideally even slower) because otherwise you'll just end up gaining a ton of fat -- see http://www.mikesfitness.com/content/how-long-to-gain-pound-muscle for how much muscle a new trainee can expect to gain with a good diet and exercise program.

If you don't gain weight, then you can forget about ever being bulky and if you gain weight too fast then you'll just end up with extra fat, so you need to be diligent with your diet to be gaining weight gradually. Besides eating right, you obviously need to lift weights. Check out the essential back, chest, and shoulder exercises here. Those exercises will be the core of your training.

What you do next is fill out the Fitness Guide questionnaire to get your recommended training and diet program. Then you adjust the training program to emphasize back, chest, and shoulder exercises more -- that means do them first in your routine and do an extra few sets compared to what the program prescribes. And scale down on leg and arm exercises since you're less concerned with their appearence.

On the whole, you have to be dedicated and patient. You will see some good progress in 2 months, but you won't yet be bulky. You'll have to keep at it longer than that. After 1 year if you do everything right you have a good chance to start looking truly bulky. Good luck!
