To use the HM Move Strength, go into your menu, go to bag, locate the HM move in the HM pocket, select it, choose "use", then choose a Pokemon that can learn it (they will say "ABLE" if they can learn it). Click on that Pokemon, and it will learn the HM move.
Now, go up to any boulder in your way and press "A". Strength will then be activated (if you have the correct badge that will allow you to use it outside of battle) and boulders will be able to be "pushed" by walking into them with the player.
It only needs to be "used" once per area but if you leave the area, ie. going up/down a ladder, you'll have to "use" the move again.
you have to use strength, which is an hm you get.
You get the hm strength and give it to one of your pokemon
You need to have Rock Smash, first. Then, go to the tunnel in Verdanturf Town. Destroy the rocks where the guy and the girl are standing, and he will give you the HM for Strength.
