How do I get my parents to stop bugging me about bulking up cuzz im transgendered?

I take it your mom does not know you are transgendered. Ask her why she wants you to work out and bulk up and also what is wrong with the way you act. That could open the door to telling her you are transgendered. If she has problems with that, ask her to make an appointment for you with a gender therapist. Your mom may think the therapist will "cure" you from being transgendered, but the therapist should help you to become the person you really are or want to be.
