It needs atleast 20 minutes a day in order to have an effective cardio exercise.
If you really wanted to have a good cardio exercise that will benefit you and have a good health and healthy lifestyle, then you have to spare your 20 minutes a day.
Personally, I think that therapy gets very personal at times, some people would rather see a recovery without having to open up about their issues with a person who they likely do not know. They might either have a hard time opening up, feel uncomfortable, some people don’t even believe in therapy! There’s that one saying “What good will talking do?” some people really have that mentality! So they deal with their issues with meds.
I would say it's a compulsion. Hope this helped!
