Restoration: If you have a 100% less majicka enchantment for restoration, and use an elastic band to hold down dual-casting healing, you can just stand in front of low-level enemies to level up. The enemies will slowly chip away at your health, and you will continue healing/levelling restoration. Alternatively, cast equilibrium opinion in one hand, and healing in the other.
Sneak: Go to Dragonsreach, go upstairs, turn right, and go through doorway on to the balcony above the main area. Sneak, and use an elastic band to keep your character running against a pillar.
Block + Armors: For block, use an elastic band to hold down the block key, and for armor, just equip the armor type you want to level. Stand somewhere where you can only be attacked from one direction, ensure this is the direction you are blocking and wait for enemies to attack you and level you up.
These may take a while, so just leave them on overnight.
