Everyone says warm-ups are essential. Everyone says they protect your voice. But when we looked at the research, the honest answer surprised us.The injury prevention framing is a recent invention—borrowed from sports medicine, where even that field can't prove warm-ups prevent injury. Meanwhile, the physiological mechanisms we assume are happening (increased blood flow, tissue temperature changes) remain largely theoretical.But here's what troubles us more: the concept of "warming up" gives singers permission to practice mindlessly. The bel canto masters understood something we've forgotten—their exercises weren't warm-ups, they were skill-building. Every repetition either builds a good habit or reinforces a bad one. There's no neutral.TeamRead by Drew Williams OrozcoWritten by Josh ManuelReferencesAfonso, J., Ramirez-Campillo, R., Sarmento, H., Santos, J. A. R., & Clemente, F. M. (2024).
