Llevar + gerundio / llevar + sin + infinitivo en el deporte

Correct: Llevar + gerundio expresses how long an action has been happening up to now: "Llevo (X tiempo) entrenando…". The construction "de + infinitivo" after llevar is incorrect here. In sports contexts, the verbs *entrenar* and *correr* appear a lot in everyday speech: "Voy al gimnasio", "Tengo que entrenar más", "He salido a correr" — this helps you remember the pattern with *llevar + gerundio*. In Spain, running and *carreras populares* (popular amateur races) are part of daily life, so you’ll hear these phrases often.

Correct: "Llevo dos semanas sin correr". Llevar + sin + infinitivo = "I haven’t been doing something for some time". The other options are grammatically incorrect (*sin + gerundio* is not possible, and you can’t insert *que* here).

The best option is with *llevar + gerundio* plus a time expression: "llevamos dos meses entrenando". The other options misuse the time expression (you can’t say "desde dos meses") or break the structure of the verbal periphrasis.

Correct: "Llevo dos semanas sin correr". This highlights the duration of the absence of the action. In everyday Spanish, people often emphasize the importance of *descansar* (resting) for health and performance — so it’s useful to know how to talk about breaks in sport too.

Correct: "Marta lleva tres meses entrenando fuerza". Llevar + gerundio = "she has already been training for three months". The form *está* describes an action in progress now, but without expressing duration.

Only "Llevo corriendo dos meses" is correct. After *llevar* you need a gerund (corriendo/entrenando), not "a + infinitivo" and not a finite verb form.

"Llevo dos días descansando" is correct and expresses the idea "I’ve been resting for two days". The options with "desde dos días" are incorrect; "Llevo sin descansar dos días" means the opposite: I haven’t rested for two days.
