I know this is total contradiction to this very domain name: fitness.stackexchange, but hear me out. Plenty of people come here asking for advice about foods, routines, muscle types, other neuro-bio stuff, etc.
I am here asking how I can gain strength without increasing fitness. It is my goal to become strong enough to deadlift 600 lbs. at a bodyweight no greater than 200 lbs. for a one-rep max.
While, yes, I do generally want a bit more fitness, what I only real care about is the ability to exert more force: strength. So this is why I want advice on strength-only, power-only routines that are not part of any program like Starting Strength (personal reasons related to Mark Rippetoe). Can someone give me some advice who is out there in the power world? Any programs (besides the latter), any tips, any other info I should know, etc.?
As stated, I can deadlift about 300 lbs. max now (and I'm in no workout routine, program, fixed diet, etc., etc.). I want to one day reach 600 lbs., preferably within 12 years, and will use no enhancements, steroids, h.g.h., etc.
Some information for those who'll make assumptions:
I am not a "noob" here, and I have lots of experience. I have just never stuck with anything and never made results that I wanted. I have lots of neuro-efficiency training (ability to exert myself as hard as possible), some explosive training like with cleans, etc. (although a lot of it has diminished), and I am quite neuro-effective (I can incorporate a lot of strength without any muscle tone/mass). I do not care about mass either, and strength, power, etc. are my goals, not endurance, long lasting, etc.
