Experiments can only be accessed by completing the Creature of Frankenstein quest (really easy).
Experiments have 1000 hitpoints and are very very weak so you will not need to bring too much food to re-heal.
Giant Spiders will automatically attack your character. So you can leave your character training while you do something else.
This type of training is called AFK (Away From Keyboard) training, because you don't even have to be at the computer to train!
Eventually the Giant Spiders will stop attacking you, when this happens leave the room and walk into the room beside.
The Giant Spiders in that room will attack you automatically.
Monkey Guards can only be accessed by atleast starting the Monkey Madness quest.
(If you do not want to start Monkey Madness see the next section, Bandits)
When training on Monkey Guards you do not need to spend any money on Food.
You use the Protect from Meele prayer and recharge your prayer points using the altar in the same room as the Monkey Guards.
Monkey Guards drop Large Monkey Bones which can be sold or buried for Prayer XP.
runescape bandit camp map location Bandits are recommended for higher levels. I advise having protection prayer on at all times, however if you have good armour and high defence you may chose to do otherwise.
Bandits will automatically attack anybody wearing Saradomin or Zamorak clothing.
This means you can train your Character without constantly clicking (except when you want to eat)
You can organise the Bandits into a line so you are only fighting one at a time (image below)
It is suggested your bring a large amount of food in noted form, and some GP. That way you can sell the noted food to the General store and buy it back in normal form. However you will loose a small amount of GP every time you do this.
