Hey Brody
Have you read the updated sticky at the top?
You can't set up correctly with plates that are smaller than the standard 450mm diameter. If the gym has bumper plates lighter than 45lbs, use those to start.
You're pulling it off the ground too fast and the bar is losing contact with your legs.
If you're intent on adding power cleans to your program regularly, you'll need to get plates that allow you start at the correct height.
