Adding the clinical framing, because it changes how the question reads. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.

Worth separating that from training through weight loss, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

Agreed, with the caveat that "exercise" for someone with mobility limitations is a different set of options, and the standard advice is written as though everyone can walk for an hour.

Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful. Thread quality here is what the rules are for. Keep it up.
