Are 14 inch arms big im 16 and im 5 10 and weigh 160 By the way im starting to lift weights and plan to get sixteens in two months is it possible?

14 inch arms are perfect! You're making good progress especially if youre 16. Getting sixteen inch arms in 2 months, however isn't very likely. But if you keep lifting and make sure you're eating lots of calories and protein, you can be there in about 6 months. I've been there before and trust me you're doing fine, don't stress their size too much. And when it's warm out again get a tan! Tan skin makes muscles look bigger! Keep working hard
