so, never saw this discussed, worth a shot.
as a kid i broke my collarbone which ultimately deposited scar tissue close to the origin of the L front delt, making its muscle belly shorter than the R front delt. and as we know, a shorter belly is a smaller one. So, not only do i have a L front delt smaller than the R, but i also have a L pec thats larger than the R pec (due to L pec having to compensate for reduced output of the L front delt).
question: would ART (or the like?) remove this scar tissue after all these years and allow the L front delt to reach same belly size as the R front delt?
would i be better served with prioritization training to address imbalances (ie: pre-exhaust & do L front delt work & R pec work, and then into normal routine)?
