Full Range Of Motion

I just left the gym. Like you, I make my observations, but don't intrude. I see those who don't know the meaning or the effectiveness of a full range of motion when lifting weights. You've seen them. The ones who push, pull, raise, or lower the weight about halfway or three quarters of the way, then get up and beat on their chest like they've really done something. OK. My bad. They did do something, but then they wonder why their muscles don't stand out or become as defined as they are capable of being defined.
