Monk Strength

I keep going on and on about this and I've been doing it for 14hours soon enough
cuz I really really really wanna know...
Is there ANY way for a monk to get 26str without constant use of drugs?
If so, how?
There is said that you can and some have proved it but never told how...
Help?

str backbone + move on would give + berzerker 1 would give +5, i cant think of a lost imp which gives +1 too
