indolent person is naturally disposed to avoid exertion:
indolent and slow in movement; an indolent and contented fisherman. The
lazy person is averse to exertion or work, and esp. to continued application; the word is usually derogatory:

so slothful as to be a burden on others. 5. worthless, trivial, trifling.
