bulking is old school. the "shotgun" method that Cord was talking about is how they used to do it and is incredibly unhealthy, and incredibly difficult w/o drugs, or at least tons of money to invest in diff supps. there are modified "shotgun" type cycles now that are in 4 or 5 week periods, where you bulk for 4-5 weeks, then cut for 4-5 weeks, and then go back and forth between those. best way is get your diet nailed in. once you get a diet nailed in, then figure out your metaboic rate, and go slightly above it. this will help you bulk up and not get all the unwanted body fat. you will also need to train for size if you want to put on muscle. there are several ways to put on size and they all work. Time under Tension is one tried and true hypertrophy method, as is higher volume workouts like GVT, but make sure you find a very balanced program if you go high volume. EDT(escalating density training) is a new technique that is supposed to pack on size quickly. WS4SB I has a great hypertrophy template w/ lots of room for sports training. it is geared towards athletes after all.
bottom line: eat right, don't go on a bulking/cutting tangent, and find what hypertrophy method works best for you.
