FWIW, for me HIIT was the catalyst to exercising.

As someone who wanted but struggled to motivate myself to take up regular physical activities, the short duration of HIIT was what sold it to me. Sure it's "intense", but I found it way easier to just push myself for ~10min (20min door-to-door) rather than finding time for a 1-2h regular exercise - which I personally don't enjoy much more anyway.

Weight loss has never been my consideration. However, what I've found over the years (and is also supported by research afaik) is that a practice of regular short HIITs greatly contributes to endurance too. Anecdotally, by doing HIITs almost exclusively I am able to keep up pretty well with my triathlon friend during longer runs.
