You don't have to hop as the guys on the video did it)) It was really funny to watch. Hopping is a natural movement when You move your weight forward for charging for the next step. So that your heal lifts in the air naturally. But those guys were just jumping for nothing))

Not sure why one would hop so much. Seems like a bit of unusable energy
It's a drill. To reinforce weight transfer and pushing off.
Тут главное принцып понять, в последствии будете стараться подбрасывать яица не в верх, а вперёд и дело пойдёт.
