Gatekeeping how people do exercise is one of the reasons why a lot of people skip on it.

There are tons of possible reasons why someone might prefer a peloton to a road bike, implying one is better than the other is just naive at best.

"Oh but you get free coaching from your peers" oh you mean more people to bikeshed how I exercise and more conflicting information? What's not to like huh

I am sorry, I don't understand your reply: did you read my comment as somehow booing peloton?

If so, that was not my intent, different people have different reasons for preferring one activity over another, I just wanted to highlight that being outdoor is useful in itself, and should be considered when choosing what to do.

I hate doing physical activity with people, so the "peers" part is especially outside of what I meant :)

Not really, I'm mostly disagreeing with whom you replied to, and agreeing with your statement: "exercise at home is still better than no exercise"

Which is why I replied to you instead of directly to the main comment.

Some people prefer to avoid the sun, especially during the high UV-index hours.

But it's not just leaving the house and being in the sun, the second you're on a road you're dealing with a constant form of socializing that just isn't very pleasant and has (for a lot of people) a pretty high level of stress you've to initially get past (cars, even other cyclists).

You can also just put them on rollers and use them inside, which is still better exercise than a stationary bike because it forces you to use your core muscles.
