How do you increase your combat level in runescape?

I suggest that you train all of your stats (attack, strength, defence) and magic and ranged if you want instead of concentrating on only 1 stat, e.g. strength (most common). Also if you want a good place to train strength, attack and defence with good drops, the 2nd floor of stronghold is very useful if you go through to the big flesh crawler part. They drop some quite good stuff, quite a lot of coins drop. If your member they drop rannar's and other herbs.
