The recommended way to gradually increase workout intensity is through the principle of progressive overload. This involves systematically making training more challenging by adjusting variables such as duration, frequency, intensity, or type of exercise. For beginners, start with manageable workouts and increase intensity by about 10% per week. It’s essential to listen to your body and ensure adequate recovery while avoiding injury. Keeping track of progress can help gauge improvements and motivate individuals to adjust their workouts accordingly. This gradual increase allows the body to adapt and promotes continuous improvement.
