Q: other ways that are best to work out your chest.

A: Bench press, bench press, bench press! It's really that simple. Use both barbell and dumbbells and mix in incline and decline bench, along with flat. I'd give priority to flat, then incline, then decline. The only other worthwhile chest exercises are dumbbell flies and pullovers (pullovers also work back lat muscles). But focus on the bench press.
