Airline pilots practice everything in a simulator, both in initial training as well as every year or so for recurrent training.
A friend of mine is a new sim instructor (and retired captain) at an airline, and he learned to teach this exact lesson yesterday. To ensure the plane bounces, they configure extreme wind shear at a certain altitude above the runway, so the plane essentially stalls and slams into the pavement.
He tried it first at 30ft, and the pilot easily handled the small bounce—too easily, he thought. He then tried 50ft, and the impact was so severe that the sim went “off motion” to protect itself from damage, and the (simulated) plane did not survive. So, the correct setting seems to be somewhere between those two values.
