I started off with a bf% of approx 25 -30 %.
I have now got it down to about 13.5%.
I know that there probably isn't a definative answer to this, but when would YOU start to bulk up at ?
I think 13.5 % is probably still a bit high to start my bulk, but I am curious to know, in anticipation of gettting my bf% down more soon.
Thanks :)

I've been wondering the same thing. I'm down to ~10% BF now, I think I'll go all the way to 8% before bulking...

...when would YOU start to bulk up My plan is as such:

Cut down to that magical 8% BF, or close.
Maintain for a few weeks, to enjoy
Start bulking
Start cutting if I get above 10% BF
Continue bulking indefinetly, cutting when BF goes > 10%
I think 8% is too cut. I think 10% is about right. One of my goals is to have those big gymnast shoulders. Hopefully my genetics will allow that, if not I'll probably realize it and pick some other goal.

I'd start bulking now. I mean think about how hard it's going to be to get down to 8%, let alone doing it twice! And when you do all that hard work for nothing? I mean when you're at 8% and then bulk it seems pretty dumb considering you spend 2-3 weeks for every pound you lose and gain 3-4 pounds in a WEEK...hmm...seems like a HUGE waste to me.
