Yes, generally speaking you don't need any advanced methods until you have been kicking ass with a 1.25Xbw bench, a 2Xbw squat, and a 2Xbw deadlift for some time now. But once you get them the conjugate method (without accommodating resistance, that is really only good for people who know their shit, and can consistently hit rep after rep with good form) is one of the best things you can ever do.
Food is also very, very important. Get some carbs (fruit for example) preworkout, and a lot of calories post workout. Make sure to always get a minimum of 1Xbw protein, and try to shoot for around 1.5Xbw. Fat in your diet is also very good.
