Consider the ping pong ball.
Its spin when you hit it.
The angle it hits the table, the angle it takes off.
Why does top spin pull a shot down? The Magnus effect.
Consider the weight of your paddle.
Now consider your arm.
Feel the weight of that arm.
Consider the swing of your arm in your shoulder socket as you hit the ball.
The swing of your hips as your paddle hits the ball.
Most sports come down to how you use the ground. And how your pelvis unites a chain of energy.
