Ollie 180: an Ollie where the skateboarder and the skateboard spins 180 degrees after leaving the ground. Both the skateboarder and the skateboard rotate in the same direction (Frontside or Backside) with the skateboarder's feet sticking to the skateboard. This trick is usually referred to as a frontside or backside 180, or less frequently and more popular with older skateboarders and/or when performed on a bank/quarterpipe, a frontside / backside ollie
The rider begins the ollie by crouching and jumping directly upward. As the rider begins to leap, instead of lifting the feet from the board, he/she "pops" the tail by striking it against the ground, which raises the board nose-first. Maintaining contact with the board, the rider lifts the front leg and bends the front ankle so that the outer or top side of the shoe slides towards the nose of the board. The friction between the shoe and the board's grip tape helps to guide and pull the board upward, while the rear foot only maintains slight contact with board to help guide it. When nearing the peak of the jump, the rider lifts the rear leg and pushes the front foot forward, which levels the board and keeps it in contact with the back foot.
Bolted onto the underside of the tail end of a skateboard, the tail guard (also known as a "skid plate") protected the tail end from skid stops and other maneuvers that would otherwise wear away the wood (commonly known as razor tail) and decrease the longevity of the tail. Typically made of plastic, these were widely popular in the '80s but their usage quickly diminished with the arrival of two-tail board designs, which became increasingly popular in the '90s.
No one had ever seen anything quite like it before, but no one knew just how transformative that moment would become. It wasn’t just that you could simply pop up into the air, it’s that it gave the rider a whole other set of opportunities to do tricks, and you don’t even have to be dependent on a ramp! As time went by, people began to add other skateboard tricks while they were airborne.
In the case that you didn't gave up after a hundred over tries, you'll start to develop a reaction to landing it. After a few hundred more tries, you'll feel you are getting off the ground and getting little air. And once you reach the thousandth try, you'll already be doing it whilst rolling and the next thousandth tries will be spent on clearing small cracks n obstacles and working towards ollieng up bigger obstacles n up ledges.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
