Hey Pooh Bear since you mention that your Dr. recomends weight gain I can tell you how to gain muscle the fastest way possible. It is a method called anarobic lifting. It is simple and quick and it will make your muscles very sore in 2 to 3 days after lifting. Done properly and loyaly you will see results by summers end. Anarobic means the lack of oxygen use for fuel. Arobic excersize uses oxygen in your blood to burn stored energy [fat] or what ever calories you have available. Anarobic lifting will litterally burn the muscle as fuel and done properly this will signal to your body to build more muscle in case it happens again. See the logic? Again I fore warn that your muscles will be very sore so drink lots of water to help romove the lactic acids. You should be drinking at least 50oz. a day anyway and lots of stretching to make room for the new muscle to develope. OK the lifting take the heaviest amount of weight that you can lift safely and lift it methodically and as quickly as you can for 6 to 10 times then stop. Wait 2 to 3 min. for the blood flow to return to normal and repeat. Do this 3 or 4 times and you are done for the day, it's that simple. Oh don't forget to stretch. You could do legs in the morning and arms at night and then repeat the whole process every few days. you can do something arobic in between lifting days it will help with the soreness but try to remain fairly inactive as possible on lifting days. I must add the disclaimer that i think lifting weights will cause excess strain on your joints at such a young age and would not normally recomend it. I also would recomend a protein powder and lots of fresh fruit especially cantilope, blueberries,cherries and pommegranit juice. please let me know what rout you choose and how it works for you OK? Good Luck and GOD Bless you.
