Lie with your back on the bench, with your feet flat on the floor. Hold the bar with an even width between your hands. Extend your arms straight up to lift up the bar. The bar should be lined up so that if it were lowered it would go straight across the top of your chest. Keep your wrists straight and bring the bar all the way down to your chest (do not bounce it off of your chest, the bar should just barely touch). Extend your arms and raise the bar back up (wrists straight).
