Hi, I'm Tim Phang. I'm 23 years old. I've been skating for about 12 years. I'm from Arlington, Virginia, which is right outside of Washington, D.C. I'm now sponsored by Universal Skate Design, and I'm going to be talking to you about rollerblading. Fast slides are one of the most difficult grinds in rollerblading, basically because there's not much space on your skate that you actually have to balance against. So, when you do a fast slide, the obstacle that you're grinding sits directly between your middle two wheels, and then you essentially stand straight up on one foot without any lean one way or the other. The faster you go when doing them, generally the easier they get, but they're a really hard trick to balance and hold. So there's a couple of variations of the fast slide, there's a front side fast slide and a back slide fast slide, the difference being which side you approach the obstacle from. When you're learning how to fast slide, you want to start on small objects, and you want to start going really slow. You can also practice stepping up to the object rather than jumping onto it until you figure out where that balance point is. And as soon as you find the balance point, slowly start grinding earlier or longer objects until you're able to hold it for longer periods of time.
