Filming with a small crew is more active than sitting in a chair, but only barely, I'd say. There's more standing, at least.
Most of the time you're waiting near the spot where you need to be, or staying perfectly still, or moving but only very slowly.
Film work (even small-scale local stuff) can be really fun but 90+% of the physical activity will be goofing off, for most of the people involved in most shoots. And of course most of the work before and after filming is sitting in front of a screen, like any other office job.
