The "talk test" is a simple method used during exercise to gauge intensity levels. This assessment determines whether an individual can talk comfortably while engaging in physical activity. If a person can chat without much effort, they are likely exercising at a moderate intensity. Conversely, if talking becomes challenging, the activity may be too strenuous. This subjective measure helps individuals maintain appropriate exercise levels to achieve fitness goals while ensuring they do not overexert themselves, promoting a balanced and sustainable workout routine.
