To raise all stats, Strength, Endurance, and Luck, all you need is Wraith Guard and Sunder. Equip any weapon, and make sure you have the Wraith Guard on. Hold X + L to switch between the Sunder and the other weapon. This will raise the stats of Strength, Endurance, and Luck by at least 90 points at a time. This also works with Keening, but it raises Speed, Agility, Health, and Willpower.
Shin "The Demon" Sanqui.
To get superhuman abilities (Strength, Speed, Agility, Endurance, Luck, Magika), you must have a Bound Mace or Bound Dagger spell and the weapons "Keening" and/or "Sunder" that you get towards the end of the game. Cast Bound Mace/Dagger and hold X + L to scroll through weapons for a few seconds. Your skills will jump several hundred points, and you can slay an entire town. The Speed increase is the most impressive, although it can be slightly difficult to handle. This trick makes you practically invincible with stats between 200 to 300 and Health, Magika and Fatigue between 500 to 1000.

There is a constant effect glitch for items that fortify your stats and skills. Basically, if you could enchant any old weapon with a fortify stat spell, you can raise that stat. All you need to do is get a weapon enchanted constant effect. Once that is done, hold X + L + R and it will bring that stat up. For 2,280 gp (on good terms with Enchanter), you can get a sword made that raises strength by 1 point. It does not matter how many points you put in -- it will jump quickly enough. Hold X + L + R and check every once in awhile to see how far up it has gotten. Note: Some other effects may be able to be used in the same way. For example, enchant a weapon with Feather and bring your weight down to 0. If you want to bring every stat up at the same time, enchant a weapon each fortifing a different stat 1 point each. Constant effect, then hold X + L or X + R. This will cycle through the weapons, giving you point gains in each of them.

Another way of boosting your main stats is to create a spell with Soul-trap and a spell that will boost that stat. Start with Soul Trap on self and Intelligence. By doing this you can get more Magicka and its easier to cast the spells. After a few casts, switch to something else. You can boost Health, Fatigue, Strength, Magicka, Intelligence, Willpower, and Luck. If you do not have a spell that enhances your stats, then go back to the merchant in the first village and buy Jack Of All Trades.

Alternately, press B during game play to display the options. Press L or R to cycle through the menus to the statistics screen. Highlight your character's health and press Black, White, Black, A, Black, A, Black then hold A until you reach the desired health level.
Ben and Pwalex.
In the Game Of The Year Edition, start by pressing B, then press R until you find the skills screen. Highlight the health bar, press Black, White(4), Black, then hold A and press B. Note: This code will become disabled if you switch screens; thus you may re-enter the cheat.
BloodLust.
To regenerate your Health, Magicka, or Fatigue without having to hold A, enable the code for the stat that you want to regenerate. While you are holding A, press B to get out of the screen. If done correctly, your stat should continue regenerating even while you are out of the menu screen. Do this with health, as whenever you get hit, your health automatically regenerates. If you go back into the menu screens and change to any other screen than your stats screen, you must enable the code for the stat to regenerate again. However, only enter the Black and White part of the codes. If you do the code for health and then want to do it with magicka or fatigue, just enter the Black and White part of the code; you do not have to hold A again unless you accidentally pressed A or loaded another game. This trick must be repeated every time you enter the game.
Thomas Hart.
To get constant health in the Game Of The Year Edition, enable the "Change health level" code. After pressing A and exiting the menu, release A, go back in, highlight "Health", and press Black, White, Black(3), then exit the menu again. This will only work if you have lost some health. Note: When you activate the first part of the code it will not effect your health.

Use the following trick for easy Magika leveling. Enable the "Change magika level" code and go somewhere where your spells or conjured creatures will not bother anybody. This should be a safe location (preferably an empty house). Start casting the spell you want to level repeatedly by rapidly pressing R.
