The front side grind (a.k.a. frontside)is the easiest trick to do in inline skating. It involves the skates sliding on an object on the insides of the chasis, like doing the splits, but not all the way down. To do this, get a moderate amount of speed, and then jump, at an angle on to the object. What I mean by at an angle is not on top of the object, but onto the corner. Once you jump onto the edge of the object, lock the edge into the groove in your skate, and keep your skates an equal distance apart. Try to keep your head up after you do this a few times, it looks better. Just ride the trick out, dismount, and do another trick.
