I can help you get started. The type of clothing you would wear is tight spandex, there is no baggage, or any form of resistance it can create. Some other forms of resistance is your weight working against you, form of your body, and also the angle in which your skates are at. The way you can reduce the resistance is changing the form in which your body is in, cutting down on weight, and also having better and more forward form with your skates.
Good Luck!
