Si bien es cierto que, como te han dicho en los otros comentarios, "hit" puede traducirse como "ir", también puedes usarla en el sentido de "dedicarte a hacer algo". Por ejemplo. Hit the road. Esta frase no significa "ir al camino", sino "ponerse en camino". Como cuando dices: Mejor nos ponemos en camino para no llegar tarde. We better hit the road not to be late. También: I have a lot to learn, so I should hit the books soon. Tengo mucho que aprender, así que debería ponerme a leer pronto. Saludos.

Yes... these uses of "hit" are very informal. It means "to go somewhere" for a (relatively) short time. So... the idea is that I might "hit" a location and then go somewhere else. I might want to "hit a number of bars" in the course of the evening so that I can check to see which bars have the most active crowd (and the hottest guys or hottest chicks). I might "hit the gym" after work and then "hit my favorite restaurant for a bite to eat" before going home. Hope this helps.

It is an informal way to speak. In the first example it means: I should have gone to the gym today In the second example it is used in a similar way and means: Let's go to some bars to celebrate Hope that helps :)

Hit (informally) simply means "visit" or "go to" (or, in the past tense, "gone" to).

there are many idiomatic expressions which use the verb "to hit". it is just like "dar" in spanish. http://www.spanish.bz/dar.htm "to hit the gym" is slang, it means "to go to the gym"
