How can walking improve physical fitness?

Answer 1

Yes, walking does build muscle in your thighs and calf muscles. It also helps to tighten your stomach. Overall, walking is good for you and your muscles. Yes it does. Any activity that involves repeated flexion of a muscle or a group of muscles will eventually make that muscle bigger and more powerful.

Answer 2

The muscles in your legs account for a large percentage of your total muscle mass. When you engage those muscles in walking for an extended period you also force your heart, lungs and other organs to increase their activity. When your body detects the demands, it accommodates and becomes more efficient. That efficiency is called "physical fitness".

Answer 3

If you had such poor muscle mass before that a little walking exercise helped build MORE muscle mass... yes, it's possible.

Muscle is heavier than fat and it protects you from injury, helps burn fat, and moderate muscle mass helps you generally look better.

Answer 4

Because your muscules will burn fat cells making them stronger!

Answer 5

Technically, yes, but it is much slower than if you, say, jog for 30 minutes to 1 hour each day.

Personally, I recommend jogging for better strength improvement.
