(+26...6) asks how does a skinny 15 year old with a high metabolism gain muscle💪?
You need to eat a lot more and exercise🏋. Stay away from empty calories like soda and candy🍬, but do eat plenty of protein and carbohydrates (meat🍗, eggs🥚, dairy🥛, nuts🥜, grains - oats, rice🍚, bread🍞) along with a healthy amount of fruit🍎 and vegetables🥕. You need to gain weight, so you actually need to eat more than you need. To gain muscles 💪instead of fat, do weight lifting and bodybuilding exercises 🏋- enough to get your muscles sore the next day. Get plenty of good sleep😴, and rest your muscles between exercises. You don't need to lift weights every day. Your muscles bulk up while your body is repairing the muscle, not while you are lifting the weights. Stay away from aerobic exercises such as long distance running🏃 and cycling🚴. Aerobic exercises will keep you thin.
