Through the last few years of training I’ve noticed my leg muscles seem to have no definition during base/build blocks, and look ripped after doing specialty/sprint/VO2 max work for a few months (even at the same weight and body fat %). Currently doing polarized which is a happy medium. I’d bet that if you did a few rotations of specialty and build blocks you would see more definition without putting on weight. Might help you FTP get that final push, too.
