I hit walls. I bulked like mad to overcome them. The result? Nothing.
As some point when you get close to natural potential there is a limited ROI. This is why I advocate aggressive eating as a beginner and cleaner bulks the more muscle you have. Also, it provides a good reason not to kill yourself with the iron once you have made great gains. (By "kill yourself" I mean 2+ hours of volume training, or 6 day splits to "re-ignite" gains.)
It is when a person has reached this point that I feel splits of different types are useful if used correctly by a natural lifter.
Don't use a split designed by a steroid user. Use a split that makes sense for your goals, and takes into account the limited ROI that BTB mentions.
This is where thoughtful applicaton of a good program to even out weak areas can be used. It does not mean going crazy on voulume, but rather a little extra emphasis on 1 or 2 lagging parts as a main focus group.
Natural lifting is not the same as drug assisted lifting, and should not be approached or implemented as done so by the, "Pro's."
