exercise – el ejercicio

(Pronounced eh-hehr-see-syoh)

To remember that exercise is pronounced eh-hehr-see-syoh (ejercicio) in Latin American Spanish, use the following mnemonic:

When you exercise, ensure your hair is tied; otherwise you might have to see a physio (ejercicio).

Ejercicio is masculine, so it's el ejercicio. Imagine an elephant doing so much exercise, he's perspiring and out of breath.
