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. Alley oop tricks on roller blading are when you approach the object facing forwards and then when you get to the point where you start grounding you jump you, you turn one hundred and eight degrees and then lock on in your grind position uh actually sliding backwards. So it is important when you are doing alley oop tricks that you make sure that you sport the landing before hand and make sure there is no one behind you because when you are grinding, you are not going to be able to see them such as you are sliding backwards. Uh solder irons are when you have the soul of your skate of one flip uh actually along the object that you are grinding. Your other foot is going to have the obstacle in between your middle two wheels, uh so when you are doing alley oop soul you will approach the object with it on whichever side you are most comfortable facing forwards. When you get to the point that you want to grind you are going to jump uh turn hundred and eighty degrees and then lock on with your foot in the sole position and then start sliding backwards. Uh when you get to the end of the object uh jump off and you make sure that you center your body while you are in the air, bend your knees to observe some of the landing. When you are doing alley oop soul you need to be careful to commit to one hundred percent to the trip, uh when you are in, when you jump you make sure that you have your feet underneath of your body, uh you don't want to stick your feet out to one side or the other because if you miss you have a tendency to uh slide out uh when you land you want to make sure that you are cantered, if you land two far back or two far forward, you will slip out two far back will end up and you kind of falling backwards and potential hitting you head and if you land with your weight too far forward , you can slip out and really bang up your knees.
