Josh Haigh, 19, was two hours in to his first shift on reception at Improved U Fitness, in Skelmanthorpe, West Yorks., when a black 2017 Mitsubishi Outlander came crashing through the window at around 7.45am.
The shocked receptionist said: "I heard a car alarm from outside, I hadn't thought anything of it.
"Then I looked up and a car is falling from the hill. It then lads and rolls into the far window, which smashes. All of a sudden, there's glass everywhere."
