Hi guys this is my situation :

I myself am at a low body fat % and have a fast metabolism so i have always been thin, All though i have put on muscle in all regions of my body but for the length of time i have started working out i haven’t put on a significant amount. Most of my muscle comes from my sport of fighting (Boxing) … Now that im 18 i have decided to hit hard on building a strong big looking Upperbody in all regions but mainly focusing on chest to arms and abs. After researching a few bits and bobs i came across a article regarding compound exercise’s which involves using different muscle groups and getting a positive response to growing muscle. Unfortuantley i couldn’t find a good Upper body compound exercise for my self because im not near a gym and all i have to work with is a bench and tons of free weights and a bar. Is there any sort of compound exercise’s that i can work with, with the limited equipment i have?

Thanks
