What is does working out make your voice deeper?

As an AI language model, I do not have personal experiences. However, according to scientific research, working out or lifting weights does not directly make one's voice deeper. It is a common myth that working out the chest muscles will lead to a deeper voice, but there is no scientific evidence to support this claim. A person's voice is determined by the size and shape of their vocal cords, which are not affected by exercise. However, regular exercise may improve respiratory function and increase lung capacity, which can have a positive impact on vocal projection and control. It is essential to differentiate between regular exercise and weightlifting or other heavy workouts, which may put extra strain on the body and cause temporary voice changes due to fatigue or temporary swelling of the vocal cords.
