There was a man taking a heavy sack of grain to market on his donkey.
It was a long way and the man got tired so he climbed onto the donkey's back with the sack.
After a while he felt sorry for the poor donkey, having to carry both him and the heavy sack.
To relieve the donkey's burden somewhat, he took the sack onto his own shoulders ...

... or you could just work it out by the free body diagrams for the motor, load, and hand.
Recall, every action has an equal and opposite reaction.
