How can the overload principle be used to improve flexibility?

The overload principle can improve flexibility by gradually increasing the intensity, duration, or frequency of stretching exercises. By consistently challenging the muscles and connective tissues beyond their normal range of motion, you encourage adaptation and increased flexibility over time. This can involve holding stretches for longer periods, performing more repetitions, or incorporating deeper stretches as your flexibility improves. Ultimately, the key is to progressively push your limits while allowing adequate recovery to avoid injury.
