Physical strength in the context of "Tug of war"

An athlete is most commonly a person who competes in one or more sports involving physical strength, speed, power, or endurance. Sometimes, the word "athlete" is used to refer specifically to sport of athletics competitors, i.e. including track and field and marathon runners but excluding e.g. swimmers, footballers or basketball players. However, in other contexts (mainly in the United States) it is used to refer to all athletics (physical culture) participants of any sport. For the latter definition, the word sportsperson or the gendered sportsman or sportswoman are also used. A third definition is also sometimes used, meaning anyone who is physically fit regardless of whether they compete in a sport.

Athletes may be professionals or amateurs. Most professional athletes have particularly well-developed physiques obtained by extensive physical training and strict exercise, accompanied by a strict dietary regimen.

A hero (feminine: heroine) is a real person or fictional character who, in the face of danger, combats adversity through feats of ingenuity, courage, or strength. The original hero type of classical epics did such things for the sake of glory and honor. Post-classical and modern heroes, on the other hand, perform great deeds or selfless acts for the common good instead of the classical goal of wealth, pride, and fame. The antonym of hero is villain. Other terms associated with the concept of hero may include good guy or white hat.

In classical literature, the hero is the main or revered character in heroic epic poetry celebrated through ancient legends of a people, often striving for military conquest and living by a continually flawed personal honor code. The definition of a hero has changed throughout time. Merriam Webster dictionary defines a hero as "a person who is admired for great or brave acts or fine qualities". Examples of heroes range from mythological figures, such as Gilgamesh and Iphigenia, to historical and modern figures, such as Joan of Arc, Giuseppe Garibaldi, Sophie Scholl, Alvin York, Audie Murphy, and Chuck Yeager, and fictional "superheroes", including Superman and Batman.

Superhuman strength is a superpower commonly invoked in fiction and other literary works, such as mythology. It is the power to exert force and lift weights beyond what is physically possible for an ordinary human being.

Endurance (also related to sufferance, forbearance, resilience, constitution, fortitude, persistence, tenacity, steadfastness, perseverance, stamina, and hardiness) is the ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from and have immunity to trauma, wounds, or fatigue.

The term is often used in the context of aerobic or anaerobic exercise. The definition of "long" varies according to the type of exertion – minutes for high intensity anaerobic exercise, hours or days for low intensity aerobic exercise. Training for endurance can reduce endurance strength unless an individual also undertakes resistance training to counteract this effect.

Strength training, also known as weight training or resistance training, is exercise designed to improve physical strength. It may involve lifting weights, bodyweight exercises (e.g., push-ups, pull-ups, and squats), isometrics (holding a position under tension, like planks), and plyometrics (explosive movements like jump squats and box jumps).

Training works by progressively increasing the force output of the muscles and uses a variety of exercises and types of equipment. Strength training is primarily an anaerobic activity, although circuit training also is a form of aerobic exercise.
