Remember when you first switched service grip from some forehand to the Continental?
That felt awkward.
Guess what, it is awkward. But it works better. So with practice, it becomes normal.
Continental.... that's the easy way of saying your serve grip sucks and you have to change it, but the guy telling you this doesn't understand the way the professionals hold the racket, so they say "continental".
So after 2 years of steady tennis, you hit continental.
Now you gotta change again to more eastern backhand side of continental for the next level.
Once again, look at the pros line up their serves. Their rackets do not align with their forearms! They look like they're ready to hit an Eastern backhand, almost. Almost.
It's called a strong boxed service ready position. A weak one would be true continental and a weaker one eastern forehand.
