cool
its cool, but very incorrect. ive been skating for about 2 years, that is kinda the basics for ollieing, but it misses some things and is incorrect for toerh things
pop- its not when u push your foot down, its usually refered to that. but its really when the tail of the board snaps against the ground and bounces up. boards that have more "pop" bounce higher. although its not a very significant difference.
you dont slide up then jump, thats impossible, as you pop you shouyld be jumping and sliding, you slide right to the end of your nose, then tuck your back foot to help clear objects. then shift your front foot back a bit back over the bolts (VERY IMPORTANT) or ull breka alot of boards.
when ur in your stance it helps to give more information about that, you should have all your wieght on your formost foot, then when ur starting to push down, u switch weight. also you should be on the ball of your back foot.
nice work tho, ill give my 5 so it stays on.
