Well, I spent about a week on Karamja harpooning tuna and swordfish, selling the cooked fish to the general store. Other than that, I would say my current training - wear air tiara and brown apron, wield rune pickax, carry some law runes and an equal amount of water. Craft air runes, walk to crafting guild, mine silver until full, teleport to Falador, make 24 tiaras, swap for rune essence in east bank, lather rinse repeat. I'll probably do this until I run out of essence (maybe another day, probably not that long) then train strength at Ankous for more essence, or just mine some if I'm feeling lazy.
