Structural balance
You asked the same question in February...
This is not a question science can answer. All you will get is opinions and those will differ from person. You have world class trainers who say it's necessary and other world class trainers saying all that horizontal, vertical etc. stuff is complete BS.
All of them will most likely be able to quote one or two studies "proving" their point.
I gave you my opinion in the old thread.
You have to decide for yourself...
lots of hindu push ups, clubs, rope climbing and pull ups
This supports my opinion that it's about scapular function and the muscles associated with it and not about pushing to pulling ratios, vertical/horizontal and all that stuff.
Overdeveloped lats (through too many pullups and/or rows) can lead to a hunched posture (see climbers). Too much pushing, too (bench press, military press, pushups etc.).
They push a lot (hindu pushups) and have a lot of lat work (pullups, rope climbing), yet they don't have disbalances. Maybe that's because they use tools like clubs which teach proper scapular function and stretch the muscles that lead to the hunched over posture (lats, pecs, shoulders).
