Lower the bar until it's a couple of inches above your upper chest and then push the weight back up. Repeat the movement for the desired or prescribed number of repetitions.

SPECIAL NOTES & LEVEL of DIFFICULTY VARIATIONS
To increase the level of difficulty, slow down the movement or increase the weight.
This is a great exercise for beginners and for those lifters on a fat cutting cycle. The beginners will like this exercise because the Smith Machine provides for a guided and smooth movement.
The important thing here is to set up the flat bench under the Smith bar properly. Take a few moments and adjust and re-adjust the bench so that it's perfectly centered.
Then, with the unloaded bar do a few practice presses and see where the bar is coming down. As stated above, you want the bar to be coming down right on your upper chest area.
