To lift the right weight for chest exercises, choose a weight that lets you do 8-12 reps with good form and moderate difficulty. This is good for muscle growth, which is the main goal for a bigger chest. If you want to build strength, power, or endurance, you may need to adjust your weight and reps accordingly. Use proper form and technique, and vary your exercises to work different parts of your chest. Some of the best exercises are bench press, push-up, dip, chest fly, dumbbell pull-over, and machine fly.
