The presenter and co-host Steve Wilson dressed in inflatable bubble suits to play Socker Bopper Bubble Ball.
However, the pair decided not to include the ball in their game and after much encouragement from Holly Willoughby, they chose to run into one another instead.
The blonde beauty instructed them: "Go long! Go long!" as they stood at opposite ends of the studio for the stint.
Before they ran into one another, Phillip warned Steve: "Be careful though, we both have the National Television Awards tonight."

They then rushed towards each other several times, with the presenter falling into a shelf and almost knocking a vase over.
And the stint went from bad to worse when Phillip then knocked his co-host over during their final round of the game.
Holly couldn't stop giggling as her co-host tried to catch his breath, admitting: "I'm struggling."
Exhausted from their vigorous work out Phillip then fell forward and collapsed.
