Which of the following describes the concept of progressive overload in fitness training?

The concept of progressive overload in fitness training refers specifically to the gradual increase in exercise intensity, volume, or duration to enhance strength, endurance, and overall fitness. By systematically increasing the demands placed on the body, individuals can stimulate muscle growth, improve cardiovascular capacity, and boost metabolic efficiency. This principle is vital for continued progress and for avoiding plateaus in physical performance.

Implementing progressive overload can involve adjusting various training parameters such as adding weight, increasing repetitions, reducing rest time, or incorporating more challenging exercises. This strategy encourages the body to adapt to greater demands, facilitating ongoing improvements in fitness and performance over time.
