Alternate speed for each rep
Change the speed of every rep. One slower, one faster, and so on. Explosive lifting can put you more at risk of injury, especially when you are not used to high-intensity workout.
Why bench press
The bench press is really good for the chest. Lower the bar your lower peck line, which will lessen the shoulder-joint stress. The opposite will occur if the bar ends up on.

Inhale and exhale
Breathe in through your nose on the way down and breathe out through the mouth on the way up.
Correct alignment
Keep your back straight, abs tight and head aligned with your body. The proper position is very important to the exercise.
