How much weight should I lift to get my chest bigger?

To increase the size of the muscles you should lift a weight which is between 75%-85% of your one repetition maximum. A one repetition maximum, often referred to as a one rep max, is the amount of weight you can lift only one time with good form and proper control. In order to safely perform the training, it is necessary for first work on your body’s ability to stabilize joints through stabilization training. Another important factor concerning muscle growth is the volume. For muscle growth (hypertrophy), you will want to use a higher volume such as three to five sets of six to twelve repetitions.
