"Practice makes perfect"
No. Turn it into this:
"Quality Practice makes BETTER"
It doesn’t matter how much you practice badminton or any other sport.
If you don’t practice correctly and use your time wisely, you will never ever get better at anything you do in life.
Please don’t be lazy.
I know it’s easier said than done, but you really have to try and move and get behind the shuttle and NOT do lazy shots that put you in disadvantage.
For example, don’t do lazy drop shots in doubles, you will only learn from hitting hard and smashing in doubles. Drop shots will only be effective IF you learn the feel of the shots FIRST and they are literally perfect just skimming the net and going over. Otherwise, please try to smash everything and get behind every shuttle.
Stay Low. Hit High.
Keeping your knees bent in a ready to pounce stance puts you in a huge advantage in terms of reaction speed/reflexes.
It’s simple science, your moves/footwork will be more powerful and responsive if you contract and then release your muscles.
Think of your body as an elastic band.
