Strides, or steps, refer to the individual movements made by a person while walking or running. Each stride typically consists of a sequence of actions: lifting a foot, moving it forward, and placing it back on the ground. The length and frequency of strides can vary based on factors such as a person's height, speed, and fitness level. In physical fitness, tracking strides can help monitor activity levels and improve performance. Devices like fitness trackers or smartwatches often measure the number of steps taken, providing valuable data for individuals looking to maintain or enhance their health and well-being.
