If you are that skinny guy, building muscle mass can seem like an impossible task as you puff and sweat and lift weights and end up exhausted with almost nothing to show for it. So why is it that those with a skinny body type seem to struggle to pack on the pounds of lean muscle they want when guys with bigger frames seem to do hardly ANY work at all, eat crap all day and still sport an impressive set of muscles at the end?
The answer is your metabolism
The same force in your body that keeps you skinny is the same process that stops you gaining muscle mass. This is because your skinny body is like a food processing furnace that burns through calories at such a rate that all the nutrients that you need to grow muscles is absorbed or wasted too quickly. This is a blessing in that the same furnace burns FAT quickly too but is a curse when trying to get rid of that wimpy body and replace it with a lean ripped one!
This does NOT mean that you should give up on the idea, because you CAN attain that muscular body if you know how!
The most immediate thing you need to understand is that you can not and will not get any bigger eating the same way you are now and then exercising. The biggest challenge for the skinny guy to build muscle mass is that they need to eat more ... MUCH more. You need to fill yourself with calories and protein beyond your comfort level often so you do not burn through it too fast and there is plenty of left over to feed the muscle that is starving for it! The best sorts of foods are calorie dense but will not fill you up too fast such as avocadoes, whole eggs, tuna and salmon in olive oil, rice, pasta and potatoes.
Another tip is that you do NOT need to hit the gym every day, the body needs time to rest so it can repair the muscles and grow them because without this rest time you do not give the body a chance to do these things and nothing is gained. -
