I think that you can get strength at the top of the lost tower south of Solaceon town. you cant get it any other way :)
You will be able to use HM04 Strength outside of battle after you defeat the 6th gym which is in Canalave City.
Teach it the HM move Strength. You will also need the badge from Celadon City which will allow you to use Strength outside of battle.
canalave city gym
Press A at a large, grey boulder to gain the power to push it.
You can't have a Pokemon come out of its Pokeball outside of battle.
well u have to had your forth gym badge.
You teach an able Pokemon to use it, and when they do, if you see a boulder that is outlined darker than the other boulders, and is in more of an oval shape, if you click A, you should be able to move it if the Pokemon that you taught strength to is in your party
To move boulders in Pokemon Gold you need a Pokemon with the HM move Strength. Selecting the Pokemon in the menu outside of battle should let you use it if you have beaten the Olivine City Gym.
You need HM strength. You can use it outside of battle after beating the Canalave gym. You teach it to a Pokemon, go up to a boulder with the strength Pokemon in your party, and press the 'A' button. Then you just walk into the boulder to push it.
