Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed.

A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).
School children perform sit-ups, a common type of calisthenic, during a school fitness day.. Calisthenics (American English) or callisthenics (British English) (/ ˌ k æ l ɪ s ˈ θ ɛ n ɪ k s /) is a form of strength training that utilizes an individual's body weight as resistance to perform multi-joint, compound movements with little or no equipment.

To do physical activity safely and reduce risk of injuries and other adverse events, people should: Understand the risks, yet be confident that physical activity can be safe for almost everyone. Choose types of physical activity that are appropriate for their current fitness level and health goals, because some activities are safer than others.
