Set the pins so that the bar rests on them a few inches above the chest. Press and hold the lockout for at least one second to take advantage of the peak contraction and then lower under control. Rest the bar on the pins for just a second before performing another rep.
Do 2 sets of 6-8 reps after your warm-up sets, leaving a rep or two in the tank on each set. Take 2-3 minutes of rest between sets.
There are times when the world is against you, when you girlfriend left you, your momma don't love you, and even your dog don't much care for you. That's when it's time for the mental therapy that only a brutal training session can provide.
