Where do you get strength in Pokemon brown?

In Pokémon Brown, you can obtain the Strength HM (HM04) by visiting the cave located in the northwest area of the map, known as the "Cave of the Ancients." Inside the cave, you'll need to navigate through some challenges and battles. Upon reaching the end, you will encounter a character who will give you the HM for Strength. Make sure you have a Pokémon that can learn the move to use it effectively in your journey.
