RuneScape F2P Best Place to Train Strength

The best place to train strength in free to play is in the third lvl of the Stronghold of Security. The place has lvl 50 giant spiders with 50 health. So you gain 200xp per spider. I suggest that you are high level and even so, you should bring food. The spider are aggressive so once you step inside the first room, they start attacking you. They stop being aggressive after a while so you can move to the next area. (Like in the map) I’ve gain 20 str lvls through this method.

You can just sit back and watch your character gain XP and occasionally eat. Enjoy!
