I’d like to thank you for your huge efforts , but please can we say : (( Speaking English requires a lot of practice and constant work. It’s similar to doing a sport: Only if you practise it on a regular basis, can you get good at it… )) or : you can get good at it ?
I would suggest:
Speaking English requires a lot of practice and constant work. It’s similar to doing a sport: Only if you practise it on a regular basis, can you BECOME good at it.
To answer your actual question, no, you should not use the word order ‘you can get’ in that sentence. When a sentence begins with the phrase ‘Only if’, the word order in the [color=darkblue]main clause changes. The subject and verb in the [color=darkblue]main clause are inverted:
Only if he resigns [color=darkblue]will I continue to work here. (NOT “I will continue”)
Only if her identity is kept secret [color=darkblue]will she agree to provide us with information. (NOT “she will agree”)
