use strength find wardens teeth in safari zone
Strength is not a TM. To obtain Strength you need to find the Teeth in the Safari Zone and return them to the Warden he will give you Strength as a reward. (I would also pick Surf up whilst your in proximity to the teeth)
Strength, but Mew is not under it! You will find a Lava Cookie, though.
Go to the safari then find this fake teeth thing, then go to wardens house and give it to him then he will give you hm strength
You need to find these teeth for the director of the safari and if you give then to him he will thank you and then he will give you strength to push the boulder and you will get a prize

You can use the move strength in Pokémon to move boulders. You can use strength in FireRed after getting the rainbow badge.

go in to the safari zone and go to the deepest area, there you will find a gold tooth and surf, then you go to safari warden and give him the tooth, he will give you strength
The Safari warden in Fuschia City will give it to you after you find his Gold Teeth in the Safari Zone.
you need to get the gold teeth, which is in the Safari Zone in area 3. After you get the teeth, take it to the warden, which is to the right of the Pokemon center. Give it to him and he will give you HM04, "strength."
To earn strength in Pokemon Fire Red it is said that one must find the Warden's Lost Gold Teeth in the Safari Zone. This area should not be skipped or you'll miss out on the strength.
