You obviously don`t know how to recognize improvement as a lifetime natural because you aren`t one. I certainly can still improve and have been doing so. I may never gain 20 more lbs of muscle or 10 for that matter, but I can increase my strength, increase my time under tension during lifting, increase endurance, ligament and tendon strength and really push the envelope as far getting lean is concerned.
I can live with that. You can`t.
You keep dodging the real issue here, if you are a lifetime natty and have been running a calorific deficit for years, (your words not mine) then post a pic now looking better, or the same as your 2006 pics.
You cant, because your old pics were enhanced, put up or shut up.
