Go to the attack dummies located across from the East Varrock Bank.
Select the attack optionfrom the combat menu
Keep attacking the dummies until you are around level 8. After this you should be around combat level 5 or 6. After you have attacked the dummies to this level, you cannot attack them anymore to gain experience.
When you have reached attack level 8, you should head to the goblin house Northeast of Lumbridge.
Here you will work on raising your combat level to 15 by fighting the level 2 goblins. You should work on your strength levels next.
Select the strength option from the combat menu:
You should raise your strength to at least 22. This normally takes a little over an hour, depending on how many people are in the house. Be sure to keep the door closed on the goblin house so they will not leave the building.
After obtaining 22 strength, select the defense option from the combat menu:
You will need to raise your defense to level 5. After you have reached level 5 defense, switch back to the attack level, and raise it to at least 10.
Congratulations! You have just reached combat level 15-16.
