Why is prolonged standing more tiring than walking?

Standing on your feet for a long time, your legs do not rest and get a lot of stress. There are several muscles that are constantly involved so that you don’t wobble or stand upright. In addition, each leg supports the entire body weight without losing responsibility, even for a short time. In contrast, when you walk, more muscles in both legs are involved. In addition, they also receive help from the core muscles that keep your gait stable. This is one of the main reasons walking does not tire as much as standing for the same amount of time.
