Its is 2-3 hours a day but EVERY SINGLE DAY. You don’t get to not show up if you are busy and have a test. Time management is huge. You have to work well with others. Maybe not “old boys” but its a type of commitment that people find easy to understand. Club sport as in travel team.
The point is that it doesn’t look any different than any high level athletic training with the bonus of no hours in the car to get to practice each day. Its far from “a full time job.”
Yes, there are teams who “own” you. They control what you eat, what classes you take, when you take them. And there are usually big scholarship $$$ involved. That is not how Ivy athletics works or is about.
