Assuming you have the best armor and money isnt a problem, I would definately go to train at ice giants and ice warriors, you can either go to the bluerite caves south of port sarim, or the ice plateau at the very north west of the f2p wilderness.
If you dont like that, lesser demons on karamja/crandor are also okay for experience, but hit slightly harder and so you'd kill less for a bagful of lobsters.
Other than those two, there isnt much else to train on.
Ditto, south of Port Sarim is an awesome place to train because they drop so many good runes there. You get every rare f2p type laws, nats, deaths, cosmics, and chaos. It is a pretty good deal. Just make sure you take some food. It will make the trip much more worthwhile. (Also after you run out of food stop by and train on the hobgoblins for a while. They have no armor basically and die really fast.)
