where should i train it

im currently 84 str on rs where should i train

Are you P2p or F2p?

p2p

with 84 stregnth, it depends on what u want. if u want fast xp i would go either to the giant red spiders in the stronghold of security or i would just train str when i am doing slayer. and if u want money i suggest going to the ankous because they drop lvl 3 clue scrolls and a lot of other good drops, or the slayer thing would work here.
