What does "progressive overload" refer to in training?

Progressive overload is a fundamental principle in strength training and fitness that involves gradually increasing the amount of stress placed on the body during exercise. This method is essential for muscle growth and strength development, as it compels the body to adapt to the increased demands being placed on it. When the body is subjected to a greater workload—through increases in weight, repetitions, or intensity—it responds by building stronger muscles and improving overall performance.

This approach not only helps in muscle hypertrophy (growth) but also enhances endurance and functional strength. It ensures continuous progress rather than plateauing, which is a common challenge for individuals following a static workout routine. By consistently adapting the training stimulus, athletes and fitness enthusiasts can prevent stagnation and push their physical limits.

The other options do not align with the concept of progressive overload. Reducing workout intensity would not stimulate growth or adaptation. Maintaining a consistent workout volume does not challenge the body sufficiently to induce changes. Focusing solely on bodyweight exercises limits the variety of stimuli that can promote strength gains, making it less effective in achieving progressive overload.
