I am not sure where I read this, perhaps it was in the old Westside Book of Methods I own (or some ebook from EliteFTS), but in any case, the author had an interesting take on this.
If you're a small guy - wherein your height is short like Joe Morrow or Richard Hawthorne - less than 5'5 or so, then staying at a lower bodyweight is better.
Big guys - tall people, shouldn't try to stay at say 148 lbs - it makes them less strong compared to where they would be if they weighed more.
My take on this; from speaking to Joe, is that if you're training for strength, you should be at a bodyweight which enables you to perform better.
With me, I have found that if I go too light - in the low 180s, I tend to lose some strength, but if I bounce up to the 200+ I also tend to lose some strength. For me, the sweetspot seems to be somewhere between 185 and 195. This seems odd but this is my observation.
This is just some interesting food for thought.
