slowing up

Gradually becoming slower

Slowing up means reducing speed or pace, identical in meaning to slowing down despite the contradictory prepositions.

Both particles convey the same idea of deceleration: Traffic is slowing up ahead.

The phrase can also describe a gradual decline in performance or energy: He's slowing up in his old age.
