Finally finished it. Let me know if there are any questions or ambiguities. :)
Instructor starts with asking player to do a forehand drive. After some strokes, instructor says he's seen enough and starts his commentary.
'He is standing too much and there is no rhythm in his stroke. He also does not use his wrist'
He then proceeds to place the player in the proper starting position for forehand drive. Midway through, he turns the players hips and comments 'this is the drive', indicating hip rotation is what powers the drive.
Once the stance is set, he says 'this is a hard stance to maintain. this is why a lot of pros do squats as part of their exercise. if you cannot maintain this position, you will end up reverting back to arm-only strokes when playing'
At 3:24, he notes elbow should not be fully extended.
At 3:40, he suggests to lower wrist in relaxed fashion so the paddle point downwards
Next, he talks about where to hit the ball. Novices tend to hit the ball at net height, but this is not correct. Ball should be hit at table height. He has the player take practice strokes and makes the following notes:
1. Around the point of impact, he says the wrist should be rotated outwards
2. Follow through should not end near the head. You want to create a triangle between paddle, head and elbow. Don't make the triangle too tight. Don't finish near the head.
3. After follow through, reset by lowering your arm inwards. (sort of like pulling your elbow). If you reset outwards, you will be at risk if the ball is returned to your backhand. You won't be able to reach it.
4. upon reset, when setting up for the next drive, start to lower your wrist as you lower your arm and get into position
Around 6:30, after some practice strokes, coach comments that his form has changed drastically. It's 80% close to pro form. He then proposes what's the other 20% difference? "it's the use of the lower body"
"Amateurs tend to end up relying on arm only. But pros get power from lower body. Amateurs, because they use arm only, the overswing and lower body play falls apart."
Coach proceeds to show the two styles, using arm vs lower body...
While showing arm only strokes, coach comments "arm only feels less natural, and because swing is too large, it's harder to prepare for the next ball. your body is out of balance"
Before he demonstrates strokes using lower body, he mentions 'using lower body will allow smaller strokes, more opportunity to set up for the next ball.' As he demonstrates the 'pro' strokes, he repeats the same things, and also says 'by using your legs, see how easier it is to follow/receive the next ball'
Next, he comments that amateurs tend to forget form when the ball comes in fast. Since table tennis is played at a fast pace, there's no time to think about how to apply your stroke. So what can you do?
'one must create good habits.'
To form good habit, he provides some practice instructions.
1. Do not hit the ball high. Hit later/lower.
2. To do this, don't stay too close to the table. Take a step away from the table, and allow yourself to hit when the ball is lower.
3. Try not to use too much arm and overswing. Wait for the ball to drop, use your body as well as your wrist.
He adds 'do not rely only on wrist. the whole arm is at play, including the elbow. The stroke should have a rhythm'
From 10~20 minute mark it's a lot of player practice, and coach stops on occasions to comment on the following:
- Footwork. Coach says he needs to move his feet. Amatuers tend to move their feet after the swing, but pros move their legs first to track the ball, and then support the stroke. He tells his student to move his feet to support the stroke as the ball location changes
- In the same vein, the ball does not always end up in the same height. When it comes lower, bend lower.
- Coach starts to hold student's hip and rotate it so the student can feel what the KNEES need to do to support continuous stroke. He suggests to the student to not stand up after a stroke, but knees are kept bent, and there should be a rhythmic movement from left to right.
- Coach comes back to footwork (~16:00). He notices the player falling out of rhythm because he is not moving his legs to track the ball. The legs must support the stroke. If the ball were always coming back in the same spot, it would be easy. However, it doesn't, so if you use only your arm for your stroke, your footwork will suffer, and you will not recover. You must move around and use your legs to position yourself and then power your stroke. He shows an example to practice footwork (by moving with legs and no arms).
- around 18:30, he comments his student's form is much better and can see a rhythm going now.
- around 19:00, coach comments student is hitting the ball to high. Hitting at that height 'is not a drive'. a drive is much lower, where you can use your legs and lower body for power. When hitting higher, one must be standing. You cannot provide power in this position. Hitting higher is a 'stroke.' (note: I know in english, a stroke has a different meaning. In korean, it seems 'stroke' refers to a standard forehand topspin stroke.) He demonstrates 2 different timings. One is when the ball is high, which he calls a stroke. At table height, he signifies it is good for drive.
Around the 20 minute mark, after commenting on high/low balls, he talks about the critical part of the stroke. He focuses on the moment of impact, and explains 2 variations of the stroke. One is a long follow through, and the other is a more compact and vertical short stroke. When do you do one or the other?
"short, vertical stroke is for low bouncing backspin balls." he asks training partner to provide a low backspin ball (he calls it a 'cut' ball). coach then strokes 'long' on a low backspin ball (and doesn't land on the table). he says it will always miss. so you must do a short stroke. he follows up with a high backspin ball, and explains that for high balls, you can take the long stroke.
as he continues to explain, he revisits the wrist movement during the stroke. the wrist flicks around moment of impact (table height). he then shows how the wrist should move. a lot of amateurs rotate their wrist the wrong way (where rotation is more north/south). he shows the correct rotation where the rotation is more horizontal. he comments that the rotation of the wrist should not show a lot of paddle. it should show less face of the paddle. it was more common to see the north/south rotation several decades ago, but no longer now.
In conclusion, he wraps up with more on using your lower body as the foundation of your stroke. If you use your legs and hip, the follow through on the arm is natural and will come very easy. And to tie in with wrist rotation, the wrist should have the paddle point slightly outwards and not directly pointed to the ground. Together with leg/hip rotation, follow through with stroke and wrist rotation and it will all work.
the end! yay! :)
