Walking Is Endurance Exercise

Walking is primarily viewed as a form of low-intensity cardiovascular exercise.

It generally does not cause significant changes in either muscle mass or tone.

Walking falls under the category of endurance exercises, which are known to build slow-twitch muscle fibers; the fibers predominantly used for periods of sustained activity. People may notice a slight increase in leg size post-walking as the legs ‘swell’ to take in nutrients and remove waste products – such as lactic acid.
