So here you go....
Do you know air has more free spaces I mean it has more intermolecular spaces between there molecules?
And also liquid has less spaces or less intermolecular spaces between there molecules?
If you know than answer is easy...
And if you don't, No problem you have learnt it now :)
So The liquid has less intermolecular spaces it is hard to move the molecules and so our leg has to apply more force.
But in air there are less intermolecular spaces so we don't need much force to move the molecules.
DONE! :)

There are two reasons for it dear buyont force causes legs to lift upward.
When did i say u need more force than water?

the density of water is much more than that of air therefore the upthrust on the limbs of a person in water is much greater than that in air as a result the net weight of the limbs in water is much less than in air hence the force required by a person to move is less in water than that in air .
hope it hlps plz mrk as brainliests...plz
