You don't need to train to learn how to get ahead. This is a principle of peaceful riding. You just need to learn to control the pedal with your left foot. When you step on the tram at ordinary times, occasionally change your foot and practice the flexibility of this foot. If you can brake freely, you can step on the tram. That's what I did when I was studying. But I want to remind you that stepping on a high car is much more tiring than stepping on a flat car.
