And training your ass off doesn't just mean increasing the weight!
I like 
I see those idiots in the gym all the time, over here everybody mistakes high weights for intensity.
Intensity is the key, wether natural or not, but when you're on you get great results if you keep intensity high. Correct form, very little breaks between sets, good mixture of rep ranges and weights, machines and free weights.
The dominant training style that I see in my gym i call it "How to ruin your joints in three short sets". Bad form, too much weight and overall hardcore attitude.
