I noticied over the years as I got bigger and bigger, that my muscles start to burn very quickly doing just normal things. For example holding up a piece of 30lbs drywall overhead with my shoulders will cause a burn to come on within a minute and after a few minutes the pain is excruciating to the point of getting very irritated. Or if i'm holding a 30lbs bag of groceries my forearms will start to burn very quickly. Why does this happen as you get bigger? Muscles seem to fatigue so quickly even with light activities.
