Which of the following is an example of an anaerobic activity?

Weightlifting is an excellent example of an anaerobic activity because it primarily involves short bursts of high-intensity effort that do not require oxygen for fuel. During weightlifting, muscles require sudden and powerful bursts of energy to lift heavy weights. This energy is sourced from stored ATP and phosphocreatine in the muscles, rather than relying on aerobic metabolism, which is used during longer-duration, lower-intensity activities.

Anaerobic activities like weightlifting enhance muscle strength, building muscle mass, and improving power and endurance in short-duration efforts. This is distinct from aerobic exercises, which typically involve sustained activities that can be maintained over longer periods, using oxygen for energy. Examples of anaerobic activities contrast sharply with aerobic exercises, such as running or cycling at a steady pace, which rely on cardiovascular endurance and oxygen consumption.
