strength without hp?

Hey I was wondering how to get from level 1 to 15 strength without gaining hp at all. I seriously cannot figure it out I know a couple quests that will boost strength using lamps but not all of them. Does anyone know how to do so?

 

Waterfall quest or whatever its called.

Soulwars.

 

alright ill soul wars. then since i do not want attack..

 

Do the security thing south of Edgeville.
It boosts you about 5 or 6 levels.
Then use the lamps (if you haven't got them) you get from the white knight in Lumbridge.
You should have about 13 Strength after.
Then just get a couple of Zeals.
