Answer: ¡Oye amigo, entrénate con un entrenador!
Explanation: The sentence that we must complete is:
¡Oye amigo, ___________ con un entrenador!
This can be translated to:
"
Hey friend, ___________ with a coach!"
First, this sounds like a order or an advice, so we should keep it in mind.
where the verbal person would be "tú"
the given options are:
te entrenar (This is written incorrectly, the verb is not conjugated)
entrenarte (this means something like "train yourself" but is not correctly conjugated)
entrénate (this is correctly conjugated, "Tú entrénate", this is an order/advice, so this is the correct option)
