Well you are probably both ectomorphs, which means your natural bodymass retains less weight... which isnt a bad thing it just means you have to put extra work in
There really is no such thing as skinny or lanky people NOT being able to gain weight.. even if your eating alot in your mind it could be still close to your metabolism....gaining weight is simply math unless you have a medical disorder of some sort if you take in more than 3500 calories than your body burned you WILL store a pound.
i often have really active skinny people come to me and they often boast of their 4000-5000 calorie in take and say they still dont gain a pound... though for a nomral person that is alot for you it may simply not be.Your BMR or metaolic rate could be quite close to that. There are alot of things that affect your metabolism, first is how many times a day you eat. The digestive process is a very active job your body needs to do... ideally a person who wants to lose weight wants to eat 5-6 meals because it means your metaolic rate will increase... also your small intestine absorbs nutriients better when its not being overloaded...
on the flip side if you are struggling to gain weight, a technique a lot of powerlifters and other athletes goal is weight gain is to eat very large meals only twice or maybe three times a day...it slows down your metabolism and youll end up with more stored... Also cardiovascular activity for 20-30minutes + increases your metaolism.. and no Cardio is not walking.. cardio is an activity that raises your heart rate between 60ish and 85% of your max heart rate for 20 minutes or more..your body wlil stay in this elevated burning rate for about 24-40hours after you do the activity...
the next thing that increases your metabolism is reisistance training... when you tear down your muscles and bone cels during a workout your body must expend a lot of energy repairing, thus increasing your metabolic rate..
so if you are trying to gain weight you have to keep all of these things in mind.. For people with high metabolisms something like Natural peanut butter is good for getting calories though if you over do it you can gain bad weight.. tut sincee your skinny it probably wouldnt be a problem for you to lose it.
and muscle being 'heavier' then fat is a bit of misconception, muscle is more dense than fat... thus why if you want to find out how muhc of your bodyweight is muscle a hydrostatic (sp) test is best... this is when you get weighed in water.. fat molecules float and muscle molecules dont so whatever your weight is the most accurate way to find out how much of you is muscle (not an easy method)
exercise really is a science you have to put how much is the MINIMUM time a week you can dedicate to exercise and you have to have some kind of idea of how many calories you take in...if you are 115 pounds you should gain weight pretty easily once you figure out what your body needs in terms of calories. You have to be a little more organized then 'i eat a lot and exercise when i can'
everyone is different trust me, 90% of people who say they eat alot and cant ggain weight really dont eat alot... sometimes people have to take in as much as 7000-8000 calories to gain because their metabolism is so high.. this is especially the case with track runners and such.
so let me know if your doing calisthenics or going to a gym and try to log what you eat
males @ 16-25 typically can have huge jumps in weight just from putting in compound lifts like squats/bench/rows/deadlifts because your body still has great growth potential/large amounts of test,but i dont know what your gym experience is and idk what you mean by you simply saying youve exercised
my current certification is in strength and conditioning so if u need help with a program i could help with that too
