You can select an attack type that gives you only defense experience. Note that this will give you no attack or strength experience.
by killing monsters
Defence training in runescape is leveling up your defence by kill monsters or people. Start of easy with goblins and when u get to a high lvl, kill greater demons.
You can level up fast by training a specific skill and focus on training that skill. Some people like to do mini games for the experience.
fist of guthix
if you're p2p with high levels, I suggest Armored Zombies. If you're a f2p player, I recommend ankous or minotaurs in the security stronghold(barbarian stronghold).

There is no command to level up on RuneScape. You have to train your stats through sheer hard work. There is no easy way around levelling up.
