How is overload defined in fitness terms?

Overload in fitness terms is defined as making the body work harder than it is accustomed to. This principle is fundamental in exercise training and is used to improve strength, endurance, flexibility, and overall performance. By applying overload, whether through increased resistance, volume of training, intensity, or frequency, the body is prompted to adapt and grow stronger or more efficient.

When individuals challenge their current capabilities, such as lifting heavier weights or increasing the duration of their workouts, their muscles and cardiovascular system respond by adapting to the new demands. This adaptation is what leads to improved fitness levels over time. The overload principle is crucial for athletes and individuals looking to progress in their training regimes, making it an essential concept in sports massage and physical fitness disciplines.
