actually, all of those things are related. chakra= brain power (will power)+ body training. if u train any of those, the others will get better, and vice versa. the more brain power, the more things u are likely able to do with ur chakra, and body power heightens ur chakra lvls even more by training. shikamaru is the best example for the brain part, and lee is the best example for the body part. its that simple. so if his body doesn't have stamina, that means that his chakra lvls are low for some reason. it means that his trains more his jutsu and mind, than he trains his body.
