My strategy as for now (only level 7-8): mage stone to raise alteration, get in combat, cast armor (atm a couple of casts makes me gain a level every time) then equip weapon and tear things down.
2hander enemies are though, they can kill me easily (i have only basic armor spells, but going to take the perks in a very short time), while mages seems to be easier than predicted.
As soon as i get 100 alteration, going to switch to lord stone + dragonskin - lasts less but it's a guaranteed 80% physical reduction.
EDIT: while i don't have the stone, one hand levels as fast as alteration due to spamming attacks

started from 20 each, now i have 37 alteration and 39 one hand
