One foot on the tail, (by foot I mean the ball of the foot which is just behind the big toe) the other foot is about an inch behind the bolts(screws) for the front truck. Basically, the back foot quickly pushes the tail down, and right when the tail of the board strikes the ground, the back foot jumps up… the tail of the board will follow up with the foot when the front foot slides forward slightly, which pivots the tail of the board upwards. Since the front truck comes off the ground first, getting the back truck up is the trick.
It's a neat piece of science art, and it also tells us something interesting. The arrows show us that the force on the skateboard is constantly changing, both in magnitude as well as in direction. Now the force of gravity obviously isn't changing, so the reason that these force arrows are shrinking and growing and tumbling around is that the skater is changing how their feet pushes and pulls against the board. By applying a variable force that changes both in strength and direction, they're steering the board.
After that I went to my regular Olley spot to practice, fell so hard three times. My legs were so fucked up from the day before. Now I feel like shit because I had problem with a 20cm ledge I landed at least 100 times up and down yesterday. I’m even capable of 50cm ledges at slow speed, but I only get the front wheel and the board up so I have to put pressure on the nose to get it all the way up.
Smile and wave – Feel free to look around at all the other people at the skatepark that stood by and marveled at your new-found accomplishments (all one of them). I’m sure by this point you’ll be picking up roses that are being thrown at your feet, and taking a well-deserved bow as they begin to chant your name. Take it all in, thank the crowd for their undying affection, and then go get a snow-cone. You deserve it, champ.
