In terms of habit formation, what has the speaker recently adopted?

Establishing a regular cinema outing on Fridays indicates a specific and consistent activity that the speaker has adopted. This choice reflects a habitual behavior, as it involves setting a particular day and activity for enjoyment or leisure, which can contribute to habit formation. Regularity is a key aspect of habits, and going to the cinema weekly establishes a routine that reinforces this concept.

The other options, while potentially positive in terms of personal growth or productivity, do not necessarily convey the same sense of a defined habitual practice. Taking up a new hobby can involve various activities and lacks the consistency implied by a weekly outing. Returning to a former routine suggests a past habit but does not reflect something new being established. Scheduling meetings consistently, while beneficial for time management, does not pertain to personal habits in the same leisurely context as going to the cinema regularly. Thus, the option about the cinema outing stands out as the best representation of a habit being formed.
