An opposite direction loop is called a Hop. It is one of the most basic looping tricks.
1. Do a Throwdown. When the yo-yo comes back, don’t catch. Rotate your wrist to push the yo-yo up and over your hand, and back down.
*Use your forefinger to guide the string.
2. Repeat this movement 5 times and catch.
*Use your forefinger to guide the string like this.
Use your wrist rotation to push the yo-yo out ahead of you.
Pay attention to the tilt of the yo-yo to get better stability in your hops.
