The clockwork "rule"
All rotations go in the same direction. Meaning, after a Bs 180 you can only do 2 rotations. sw fs 180 or bs halfcab.
If I want to do a fs halfcab (which I do often
I have to do a fs 180 (no comply) or learn proper nollie fs 180s.
The tricks only count if they are popped well, you ride away clean and don't have to push in between.
If you apply the clockwork "rule" to 180s and shuv its alone, you can skate flatground for hours.
4 tricks in a line without pushing is another fun one.
I don't like doing the same trick back to back, except for the no popped shuvs. Those are fun. But only two in a row, I think it would look a bit strange if you do like 20 kickflips in a row, but that's just my opinion.
Another fun one.
You know in parking lots, they have these stripes on the floor, like where you have to park the car? Ollie over them. That's the quick ollie challenge.
