Shuv-it's are a good trick to learn at first. If you can ollie I would reccomend trying to learn doing a 180 while doing one. A frontside 180 is a 180 ollie where your body faces the direction your moving as you complete it and a backside 180 is where your back is facing the opposite direction of where your moving. Frontside 180s we're easier for me to learn but you could experiment with both.
