Well just because YOU are into fitness/health/training does not mean that anyone else has to be interested in it or care about it in the slightest.
My brother is into restoring cars the same way you are into lifting (and probably spends a lot more time /day working on his cars than you do training), so how is his interest and priority any less or more lazy than yours???
You say he is lazy because he does not care about fitness and eating and training and has a spare tire around his waist, and he will say you are lazy because you are wasting good car restoring time playing with weights and worrying about what you eat when he feels he is doing perfectly fine on his diet.
So who is lazy and who is not??
I don't believe he is lazy or a sloth as he also has a highly payed high pressure job, and spends hours every night working in his shed toiling away. Not a sign of laziness to be seen.
