lumbussit isn't the sprints making their legs big. long distance runners are skinny, and they run alot, so why dont they have big legs too?
you are wrong again. you obviously never tried sprints. the build the hell out of your hammies which are about 70 percent of your total leg mass i believe. they also build the middle quad and hip flexors. long distance runners dont go all out like sprinters. sprinting is closer to anaroebic than aerobic excersise. long distance running is not all out its just pacing. with sprinting you are putting as much force as you can into each stride, every stride your putting a 100 percent effort each stride is max effort. long distance running each stride is probably closer to 10-20 percent effort if you know what i mean
