Frontside Feeble Grind
Typical in the skate world, the Frontside Feeble Grind is the best place to start when learning this trick.
It can be done Backside as well, but I would suggest getting super comfortable going Frontside first.
This trick is basically the opposite of a Smith Grind.
Rather than grinding the back truck and hanging your front truck inside the ramp you, instead, hang your front trucks over the top of the ramp.
The same applies to any ledge or curb the trick is performed on. If it is a rail the truck hangs over the farther side from the launch point.
This is a great trick to have in your arsenal and with enough practice you will be nailing it in no time!
