First I will label all the free player recommended kills =)
F2P free 2 play
Level 3:
Go straight to cows. The best place to find cows would be beside the Crafting Guild, south of Falador. You should keep training on cows until about Level 30 or 40. Try to use a long sword of the best metal you can use.
Level 30 (a):
Al-Kharid Warriors are a good place to train now. They can be found in Al-Kharid Castle. Be careful though, they group up when you attack one so always bring some food as there is a bank located next to the castle
Level 30 (b):
Another place you could train at Level 30 is at the Dwarf Mines, on dwarves. There are plenty up the top near the trapdoor to go down. There are also some near the anvils. This can be accessed at the dwarf village or in one of the houses in Falador
Level 30 (c):
Another place to train is Dark Wizards. These can be found in the wilderness north of the Dwarf Mines, and near Delrith, south of Varrock. These auto-attack. Bring food as the dark wizards use weakening spells
Level 30 (d):
Level 13 zombies are good to train on. They can be found in Varrock Sewers and Edgeville Dungeon, zombies are pretty weak and are good to use magic on if you can use the spell “crumble undead”
Level 40 (a):
Hill Giants are what you should kill. They are found in the Edgeville Dungeon. You can get a Brass Key which gives you access to a ladder that leads straight to the Hill Giants. These are also great if you are raising your paryer as they drop big bones.
Level 40 (b):
Hobgoblins are where you're heading now. Try and keep to the Level 28 ones. These can be located at the back of the crafting guild and stronger ones are located in Edgeville dungeon and Crandor Island
Level 40 (c):
Ghosts are another good place to train. They can be found in Melzar's Maze, which is located next to the crafting guild, and level 28 Hobgoblins
Level 40 (d):
Level 24 zombies are another option. They can be found in Varrock Sewers. Yet again I remind you about the crumble undead spell if you wish to use magic
Level 50:
Jail guards are a great way to gain experience. They are found near Draynor Village. Once you attack one, they will all attack you, so once again, you can multi-task. And no need to worry about food either - once you die, just walk from Lumbridge back to the Jail Guards (don't have more than 3 items if you are using this method). You can keep training on these until Level 70 and beyond, or you can move on.
Level 60 (a):
If you've still got the key to Melzar's Maze from the Dragon Slayer quest, the skeletons are a great way to train. You can also find Level 45 skeletons in the cave where you find Elvarg.
Level 60 (b):
If you want a change, you could try Deadly Red Spiders. These are found on Crandor, and in Varrock Sewers.
Level 70 (a):
You are starting to get to the point where it is getting very hard to find good monsters to train on. You will do perfectly well if you are still with Jail Guards. My advice is to stick with whatever you have found to be good experience previously.
Level 70 (b):
Lessers are good to train on at around this level. They have quite a low defense, so are quite easy to kill. Occasionally you may be able to snag a Rune Med. You can find them in Crandor
Now you know basically what you should train on in Runescape for free players. Hope this helps.
