The bench press is one of the best chest exercises to do if you weight train. Nothing is better for building mass in the pectoral muscles. It's also an easy exercise to perform properly as long as you keep your rear end on the bench and keep a natural arch in your lower back. Try pulling your shoulder blades inward as well so you contract your upper back muscles and pop the pectoral muscles out so they get targeted better while you bench press during chest workouts.
