Question is, how to get that "exercise". I am going to be downvoted, but I am convinced sex twice a week is more or less sufficient for the "exercise" part.

I doubt it. It doesn’t target enough muscle groups and you ideally need some variations of push/pull/lift as muscle groups are engaged in different ways for different motions.

Probably not fantastic for cardio either, ideally you want a lot of training in zone 2 for endurance and some training at max for power.

Everyone their own. I prefer to feel fine without a training regime and without assuming that everything I do is insufficient. I feel very good with that attitude and approach. However, I am not overweight, so its easy for me to feel that way.

Smokers feel absolute fine for years. Until one day they don't.

Humans feel absolutely fine for years, until one day, they die.

Because it's not even close to sufficient. Your "conviction" doesn't hold a candle to established medical knowledge.

"Established medical knowledge", don't make me laugh! According to that, I should have a countable number of covid deaths in my family and friend circles, even our (ex) chancellor told us via media that everyone will know someone who died due to covid. Apparently, I am not everyone, and my friends apparently are not everyone either.

"establish knowledge" my ass.

Ahh so you’re a Covid denying loon. This makes a lot of sense now.

That seems like a very uncharitable interpretation of what the poster said. I interpreted it as "Medical studies and statistics don't always map perfectly to the individual case."

I think I should remind you that you’re defending someone who is “convinced” having sex twice a week is sufficient exercise.
