Camera department primarily, started as a field mixer though. After a few years doing “the Hollywood thing” I went to more corporate/convention/event work.
You definitely need to be a bit in shape though working in the industry will likely do that for you (when they aren’t feeding you greasy cheap food like pizza that is). When you’re really moving and working it’s not so bad, standing around bored is when you feel it lol. Generally there’s always something to do though so that’s not a big issue.
You definitely feel the 10-12hr days after several days in a row of shooting so good form/safety is everything. Mantras like “lift with your knees” aren’t polite suggestions, they’re law if you want to keep working and not destroy your body.
It’s tough I won’t lie but there really is nothing like it and I made some of my dearest friends on set.
