In basically any area of strength training (olympic lifting, powerlifting etc) you hear people talking about structural balance, especially around the shoulder girdle. Lots of coaches will propose ratios of pushing to pulling that you should have in your program, and some coaches will also propose ratios between bench press and weighted chins, for example, that you should meet in order to have structural balance around the shoulder girdle.
Is there anything equivalent in GST? Is there any sort of ratio or measure that demonstrates good structural balance between pushing/pulling or around the shoulder girdle in general?
