Cool! I was actually planning to start a workout routine for the summer to get back into shape and build some muscle. My question is what are some good workout routines for your upper body, specifically the chest muscles?
Are you trying to bulk up or develop lean muscle (this determines weight and rep count)? What will you have access to? Assuming you have access to almost anything, and since you want to specifically target chest muscles, might I recommend dumbbell bench press (incline and flat), dumbbell or cable flyes, pushups, triceps pulldowns, and dips to target your chest muscles. Try doing some research on these to find out what you like, and find others to increase variation. After that it's up to you whether or not you want to do full body every second day, or have specific days to target specific muscle groups (chest/tri day, back/bi day, leg day etc).
