- Q:I am a beginner, thank you master advice ~ ~!
- Swinging handsBeginners are afraid of falling when they are skating because they feel a sense of balance is not good, so you can use your hands to swing your balance.Large or small crowdsFor beginners, it is better to study in a larger skating rink or in a crowded rink, so as to avoid studying at the end of Saturday.
- Q:How do you slide the four wheel?I just want to learn how to turn on board and standing, and how to push
- 1. First, the slide is good: focus on the foot that does not move. When the body is sliding, the body is slightly forward, and there is no trick.
- Q:How do you slide two skateboards?
- Two, start1. Basic startup methodPlace the left foot (or right foot) at the proper position on the head of the board so that the panel is parallel to the ground.The body's center of gravity on the left foot, left foot slightly bent, right foot pedal to promote the vitality board, and then the right foot at the end of the board.Extend your hands to balance your body, slowly bend your knees and lower your weight.
- Q:What are the standards for skateboarding masters?
- Downhill slidingTry to choose a longer slide, it is best to have both the rapid decline section, the middle speed decline section, and there is a buffer section extending further, this kind of slide is most suitable for beginners to practice downhill slide. Downhill slip technology focuses on control, speed is second. You must learn to steady slip, when in the downhill slide, slide your feet on both ends, or need to do is turn to meet through action, to the feet to slide the face and body should be towards the front, the body crouched down, thigh close to the chest, hands out.
- Q:Skateboarding is a sport that uses a skateboard to glide on a hard surface, and gliding is the most basic technique.
- 2) Ollie action:The rear tail point under the forefoot force center, while the body upwards jump, turn the board forward over the instep front pull out, followed by the rear skateboard jump into the air (the foot is very important, the board level), and as far as possible before the feet, body, air balance. In the whole process of Ollie, the eye should always look at the head of the board, but the center of gravity should not be placed on the front foot and between the feet. When the hind leg is at Ollie, "closing" is an important step.3) exercise points:Many beginners are more willing to practice in situ when they are afraid of falling down. This is bad for practice. It may just be to find the upward feeling, and without the experience of the forward, it is difficult to make a good Ollie in the taxi. But being in place is a good way to experience the action. Therefore, more emphasis should be on the basic skills of skating, skiing and basic balance training, plus downhill exercises, the skateboard has been able to make certain control, and then practice Ollie, may be twice the result with half the effort.
- Q:What are the skills of skateboarding?
- 4, downhill slide, as far as possible to choose a longer slide, it is best to have both the rapid decline section, medium speed decline section, and there is a buffer section extending further, this slide is most suitable for beginners to practice downhill slide. Downhill slip technology focuses on control, speed is second. You must learn to steady slip, when in the downhill slide, slide your feet on both ends, or need to do is turn to meet through action, to the feet to slide the face and body should be towards the front, the body crouched down, thigh close to the chest, hands out.5, circling skills, slippery hand will slide forward, and then stand up, feet straddle stand, left foot can move flexibly. Press the weight against the end of the plate so that the end of the board is raised one or two inches. When the plate is in the air, the body rotates clockwise; when the front wheel hits the ground, the skateboard deflects to the right. Put the series together and practice.6, under the ridge near the Ridge Street skills, will be moved to the center of gravity of the foot. Lift the front wheel at the end of the plate across the ridge. Stay in this position, crouch slightly, and get ready.
- Q:How to buy four wheel skateboards?How do you choose skateboards, just for beginners?
- The first is hardness, and the slide wheel is usually the main material for polyurethane. The proportion of polyurethane in wheel is different, and the hardness of wheel is different. The hardness of 85A (A refers to the wheel hardness) is relatively soft, suitable for rough pavement sliding, sliding a small voice, is a good choice for love push shopping friends. But the wheels of 85A are softer, so they are not wearable, and it is easy to break the interlayer when doing things like side brakes. In general, all hand wheels now use 97A-103A wheels. Such hardness wheels are suitable for smooth marble as well as for flat pavements, as well as for U, platform, and diving platforms. On smooth, smooth surfaces, such as the wheels of 85A, there is no sound. But in the rough and U pool, will issue a huge long song (the sound often makes plate hand blood). The transparent or translucent wheel does not see the 103A. It is too hard and will burst. It is better to use it only on all the props made of WOOD material.
- Q:How do you stop the skateboard?
- 1. one foot on the board, one foot on the ground2. the center of gravity is slightly tilted toward the back of the backboard and behind the ground, but this method is more wear to the plate3. direct one turn emergency brake4. is similar to 2, but the shoes rub against the ground, and then make a turn, so the shoes wear much more
- Q:What board should I buy for skateboarding beginners?
- 2. slide support (truck): slide support, also known as Truck, the bridge plays an important role in the performance of the skateboard. At present, most of the bridges produced in the United States are made of special aluminum alloy, and almost no fracture occurs. The bridge distance of the slide bridge is different. There are 126mm, 129mm, 134mm, 139mm, 146mm and so on. The bridge with different bridge distances, with different width of the surface, makes the skateboard more flexible and easier to control. The bridge is also different in height. High bridge is suitable for large wheels, a low bridge for containing relatively small wheels, so slip up will be more comfortable, not easy to happen when the wheels touch panel bending caused by excessive bending or rupture of the main nail. INDY, VENTURE, DESTRUCTO, THUNDER, ORION, GRINDKING, TITAN (Nissan) and other bridges are good. INDY is known as the king of the bridge, and its quality is self-evident. VENTURE uses quite a lot of people in the United states. DESTRUCTO is the number one bridge in the United States, and also my favorite bridge. DESTRUCTO is very smooth when it does the action of the round bar bridge (such as 50/50, 5/0, K-GRIND, etc.), and it doesn't move around. It's very steady. The PU pads on the ORION bridge are good, they're tight enough to be as hard as stone, and they don't explode when they're used. GRINDKING bridge is the lightest, but he is not very rigid shaft, jump more will bend, and not wear-resisting, but it's the main bridge nails pretty good, is the kind of anti installed. TITAN according to the friends who have seen it, it's very nice, very beautiful, very light, and rustproof, but it's more expensive than the usual bridge.
- Q:Learn the art of skateboardingFocus on how you skate after standing on the skateboard and declare the 2 tires
- C. The front foot and head plate rose to the highest point (start with Ollie do not consider the front pull board), under pressure or in the head along the front and rear foot fall down along the tail rise upward, the foot should stick the tail feeling;(Note: if B is done not rise, will naturally lead to not taking back)D. When the foot along the height of the board received some tail (tail stick can not lose feeling), feet had sticky feeling, this time has been vacated, and only after the fall can buffer.
