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.
Research has shown that walking at speeds of 3.5 to 4.5 miles an hour - that's brisk walking, not strolling - produces cardiovascular benefits. A woman of average size can walk comfortably at brisk speeds of 3.5 to 4 miles an hour, while the average-sized man can walk at 4.5 to 5 miles per hour. Slower walking (2 miles per hour) can be advantageous for older people, cardiac patients, or people recuperating from illness.
