trust me, being skinny and tall is not that bad so long as you dont have an eating disorder or are in denial about having one as many people are. Don't wory so much about being embarresed and being skinny in the gym since chances are most of the guys didnt start off buff and know where you are coming from. High cal, high protein, lift heavy, low rep. So thats 2-3 workouts per muscle group(bicep is one group, tri is another etc etc), 10 reps each, 3 sets per workout. Break up the workout if you can into day1(back/bi) day2(chest/tri) day 3(legs, shoulders) abs every other day. Thats not my workour but I hear thats pretty standard. do that cycle twice a week and rest on the 7th day (just like God!). If you are eating normally, and you dont have an eating problem, try and eat much more than what you normaly would lots of chicken and rice. lean meats are good. The thing is though, you have to take the first step and join the gym. There is lots of talk on this site with guys who want to start but how many of them actually do? The one key when you do start is: patience!!! Do not expect a qucik fix, everyone puts in lots of time and effort to get to where they are. Some cheat and take short cuts, but that will catch up to them in the future. I hope this helps.
