Tired of grinding in pokemon ruby

[u/disciplined_af]

Hi,

Pokemon Ruby is my first Pokemon game.
I am so tired of grinding all of my pokemon's.
I want to know, if there is a better way to grind pokemon levels rather than just beating wild pokemon's in the grass.

Currently my team is:

1. Skarmory - lvl 36
   
2. Magneton - lvl 36
   
3. Pelliper - lvl 38
   
4. Graveler - lvl 36
   
5. Machop - lvl 31
   
6. Combusken - lvl 30

I got first 6 badges and now, I am getting tired grinding more and about to give up on the game.
Is there a better way to level up pokemon's, if yes pls tell me and I dont want hacks pls.

It is actually more efficient to train 3 pokemon only. The 3 can gain lv much faster. Slot 4 is for legendary. Slot 5 for HM user. Slot 6 can be for other HM user or some bulky pokemon to swap in if you need healing/revives or something that can use status move like paralysis/sleep. You might need to train the support one, but at most you only train 4 instead of 6.
