What type of exercise includes rhythmic activities that use large muscle groups for an extended period?

Aerobic exercise is characterized by rhythmic activities that engage large muscle groups for extended periods of time. This form of exercise relies on oxygen for fuel, promoting cardiovascular endurance and overall fitness. Activities such as running, swimming, cycling, and dancing are typical examples of aerobic exercise, where the body maintains an elevated heart rate over time, improving the efficiency of the heart and lungs.

Anaerobic exercise, in contrast, involves short bursts of intense activity where the body relies on energy sources stored in the muscles rather than oxygen. This includes activities like sprinting or heavy weight lifting. Muscular strength focuses on the maximum force that muscles can exert in a single effort, while flexibility pertains to the range of motion in joints and muscles. Both of these do not necessarily promote sustained rhythmic activity like aerobic exercise does.
