Pushups of course. The best pectoral workout certainly.

jumping rope with a lot of crossovers.

for the recommendation on push-ups, i will say that specifically wider push ups will work that area better. bench pressing of course will too - and the more width between your hands the better.

barbell and dumbbell bench press

incline barbell and dumbbell bench press

pec flys

wide grip push ups (wider grip focuses on your pecs more)

Push up bars isolate the chest. Dips work them very well and if you want to add mass then get a dipping belt. It will give you more functional strenght than other types of weight lifting. Sport specific stuff with medicine balls is good. I just use push up bars, dips with no weights, perfect push ups & knuckle push ups because I box.

diamond push ups

For adding size stick to dumbells.

incline/decline/flat bench press
