Try sliding a bit more weight onto the bar today. The heavier weight may make using good form tough to remember, so think about keeping your forearms as close to vertical as possible at the bottom of every rep and your feet firmly planted on the ground. Resist the urge to bounce the bar off your chest. That's just cheating.
It's still important that you follow my nutrition program. You might be completely destroying your workouts, but if you can't stay disciplined in the kitchen as well, you won't see the best results.
