What starts out unable to move then on all 4's, then on 2, then on 3, back to 4, finally unable to move again?

A human. Crawls on all 4s as a baby, walks on two legs as an adult, uses a cane and both legs (3) as a senior, then a walker when even older (4 again), and then dies and never moves again.

Humans...with socks.

On all fours is when the human is a baby, crawling on hands and knees.2's is walking upright as a young person.3's is an elderly person with a cane (two feet and one cane) and then you die after a while.

See, in babyhood, they can't move, then infants crawl (4) then children and middle age people 2 legs, then old people 3, 2 legs and a cane. They they die.

Have a good evening.

If you pick me as the best answer, please leave a comment.
