Umm...you don't NEED to have it to beat that part.

Answer 1

You can obtain Strength at Nimbasa city in a house at the North side of the Battle Institute. Two houses to the left of the Pokemon Center and talk to the Ace Trainer.

Answer 2

In nimbasa city (the city where you fight elesa the electric gym leader) go to the Pokemon center. right next to the Pokemon center, is the battle institute. Go around them both and enter the building behind the battle institute. An ace trainer will be sitting at a table. talk to him and he will give you the HM for the move strength. Strength is used in battle and to move giant rocks in the region.

Answer 3

From the Nimbasa City Pokémon Center, go behind the building and follow that street to the left. Go all the way down and enter the very last building, then speak to the blue-haired NPC to get the Strength HM for free.
