Progressive overload is the cornerstone of long-term fitness improvement, and it’s rooted in the principle of challenging your muscles by gradually increasing the demands placed on them. This can be achieved by adding weight, increasing reps, or reducing rest time between sets. By consistently pushing your limits, your muscles adapt and grow stronger. This incremental approach ensures that you're always moving forward, avoiding plateaus and encouraging continuous progress. Whether you’re lifting weights or performing bodyweight exercises, understanding progressive overload will help you optimize your gains.
