The correct technique is to lift the bar off the stand, inhale as you lower the bar to the chest. The bar should gently touch the chest, but should not rest on it. When you are lowering the bar to the chest, it is important that you do so at a controlled pace. In case you lower the bar too quickly, you will lose control and the bar will strike the chest. If the bar strikes the chest with great force, it can cause fracture to the sternum or to the ribs. Now slowly begin to press the weight up towards the starting position. Exhale, when you pressing the bar up. The end stage would be to fully extend the arms and lock your elbows. Then lower the bar again to repeat. The most important of the tip is not to arch the back and lift your feet off the floor, when you are doing the exercise.
