Circuit training is a form of exercise that involves moving through a series of different exercises or "stations" in a structured manner. Typically, each station targets a different muscle group or aspect of fitness, such as strength, cardiovascular endurance, or flexibility. Participants perform a set number of repetitions or time at each station before moving on to the next one, with little to no rest in between. Circuit training is known for its efficiency and effectiveness in providing a total body workout in a relatively short amount of time. It can be adapted to various fitness levels and goals, making it a popular choice for individuals looking to improve overall fitness, lose weight, or build muscle.
