Big Dan, Elle has it down correctly. Guys always want big arms because girls think they are sexy. But remember this sage advice. The squat is the king of all workouts. It is the one exercise that ties nearly every muscle group together. Do not forsake this exercise in your workout regimen. Only work out your legs once a week and do leg stretches daily. Feed your muscles after you break them down during the rest time in between workouts. As for arms, work your arms every 3 days. Alternate working triceps and biceps. Big biceps equals big biceps. Put those big biceps in a picture frame of big meaty triceps and girls will figure out a way to squeeze them. Never ever neglect your triceps. You can work them on the same day. There are tons of fitness sites on the web plus YouTube to surf and get way more info, but Elle summed it up properly and I just expanded upon her great answer. So get after it and grow those pythons!
