Weightlifting for girls basketball athletes.

So my weightlifting program at school is designed with pushing your muscles to the limit. (Bigger Faster Stronger) As an exam we do a thing called survivor which is where you do three core lifts (bench, clean, and squat) for 9 minutes. You get as many reps as you can and you have quite a bit of weight on. I have recently heard from my orthopedic surgeon that that causes you to bulk up, and it will mess up your shot. He asked me how many reps we do for a regular routine and I said 3 sets of 5 reps. He couldnt believe that as a girl I was lifting like that escespially when I am in basketball. Does lifting like that really affect my game or shot in basketball? How should I be training?
