Probably the major advantage of walking upright was that it freed the hands to use tools and carry (the pray). Another advantage is seeing further than on four legs, without the need to stop walking and raising oneself for a little while to look around ( like some animals do). Comments. Report.
Rather than creating large, bulky muscles like those heavy strength training can build, walking will keep muscles relatively small. For a muscle to become bulky, it must be continuously overloaded with very heavy resistance and even then bulk is not a guarantee. Obviously, walking does not meet this requirement. Instead your legs become stronger as your fitness improves. The primary impact walking has on your muscles, is improving muscular endurance, which is the ability of a muscle to repeatedly contract for an extended period of time.
