Bodypart split training (the stuff you read about in magazines where you do a different body part every day) became popular when big name bodybuilders started talking about their routines. Only problem is, these guys are juiced to the gills. Steroids change how your body responds, and therefore how you train changes. And even many of the top name bodybuilders actually train certain bodyparts multiple times per week.
Natural athletes have to go about things differently. You want to maximize your natural hormone production. The way to do this is to place as much resistance as possible on the biggest muscles of your body. The way to do THAT is through heavy compound movements. Squats, deadlifts, bench, rows, pullups, overhead press. Think squats and deadlifts combined with any movement where you move a barbell closer to or farther away from your body.
These movements will force your body to adapt by releasing a crap load of testosterone. You'll get bigger and stronger, and testosterone also keeps you lean even when you eat more food.
Conversely, if you focus on isolation movements you won't force your body to get stronger. You'll remain weak and small and die alone.
I'm sorry. I'm watching metalocolypse and feeling very brutal at the moment.
