What happens if you overused accessory muscles?

Overusing accessory muscles can lead to muscle strain and fatigue, as these muscles are not designed for prolonged exertion. This strain can result in discomfort, reduced range of motion, and potentially lead to injuries. Additionally, relying too heavily on accessory muscles may indicate improper breathing techniques or underlying respiratory issues, which can compromise overall efficiency and lung function. It's important to ensure proper technique and engage primary muscles to avoid these complications.
