If you're focusing just on increase your main lifts (and not aesthetics), make sure you hit your accessory exercises hard. Possibly even harder than the main lifts. For the deadlift and squat, hamstring, glute, and lower back work is a must. Best exercises are reverse hypers and GH raise.
If you don't have access to the equipment, do lots of back extensions, pullthroughs, kettlebell swings, Romanian deadlifts, etc. For the bench, hit your triceps and lats hard. Lots of extensions, JM presses, close grip benches, every kind of row imaginable. When your accessory work improves to that of a 1000lb lifter, you will become a 1000lb lifter.
