Using "pensar + infinitive" say what these people are planning on doing. Remember that for reflexive verbs, you need to use the appropriate pronoun, which will be attached because pensar will be conjugated. Remember to capitalize and punctuate and use the verb "entrenarse" for working out, not hacer ejercicio.
