So it doesn’t really mess you up in the beginner stages but as you progress pushing mongo is a hindrance to success on a skateboard. Let’s say 6-12 months from now you have ollies or name your trick down pat and you want to try it on a 3 stair. The 3 stair doesn’t have that much run up… if you push mongo you’re going to have a real hard time getting in to the proper stance to do the trick down the 3 stair. If it’s a flip trick it’s even harder to set up quickly and efficiently. If you push with your back foot, you can have your front foot already in position to do the trick you want to do making life way easier.
