http://www.liquid-lifestyle.at/en/summer/seminars/rueckensch...Ergonomic exercises. Does your article talk about ergonomic training or indeed include other things as in the link above? If it refers to helping associates become more self-assured, team players, "better"workers, the emphasis would IMO be on a program designed to strengthen them, making them stronger, more successful and not just having their back = supporting them when needed. Even "backing you up" would seem a more incidental help although I imagine "backing you up/we'll back you up" could be taken as straightening your back (out), so to speak, thus figuratively alluding to the "making you stronger, better, more successful" meaning.
From pain to gain?
