This is why I hate it when people are obsessed with training to failure. When they start to get tired their form always suffers, and they end up engraining really bad habits. If you were coaching someone to throw a certain type of pitch, but after a while they were getting tired and having trouble, you'd tell them to stop because they weren't going to improve if they didn't have the energy to put into the technique. How is lifting any different?
When it comes to programming, people always get it backwards. The don't care about technique on bench or pull ups, but don't you DARE sway when you're doing curls! In fact, lean on that wall. That'll keep you from swaying.
