How do you say 'work hard' in Spanish?
How do you tell someone to work hard in spanish? for example in the context of, "work hard! you can do it!" ?
Trabajar Duro is a new, Americanized way of saying: Trabaja mucho, intensamento o sin descanso. If you are looking to create an advertising be very careful to look at the audience and geographic location.
Trabaja duro may not feel the same in Mexico that Chile or Spain. If this is to be use in USA Trabaja Duro is very accepted. Trabaja Duro, tu puedes lograrlo!
Trabaja fuerte, tu puedes lograrlo!
this is an bad example of not knowing the way people speak in different regions:
This is a German Vacuum Cleaner advertising created for USA.
Zion, the vacuum cleaner that really sucks
Esforzar is probably the word that you want. It means to make an effort. Also esfuerzo is the noun "effort". You could say "Da tu mejor esfuerzo" but I have no idea if a native would ever say that. It would mean "Give your best effort" if it translated correctly which it may not.
Trabaja duro, tu puedes hacerlo Da tu mejor esfuerzo y lo lograrás (give your best effort and you will do it" This one is a slang used in México "héchale todos los kilos y lo lograrás"
