The back shot has become a GPP trademark. Deservedly so. There is no other shot so telling of someone's complete fitness.
If someone has great legs, it is a fine accomplishment, but is really says nothing of the rest of their fitness. We've seen a lot of folks come through our doors with amazing lower body fitness, but were lacking in upper body strength and endurance.
If someone has terrific shoulders, arms and abs it is surely noteworthy. Often, worthy of praise. But, just as often - it is not. Thing is, shoulders, arms and abs are usually the FOCUS of one's fitness ambitions. Generally, they are the only things fit on the exercisers body. Some folks will strengthen the "show" muscles and pay little or no attention to fully functional fitness. There is no health in this. It is not a worthy pursuit.
However, this is almost never true of the back. NEVER. If one has a truly, well-developed back and has put in the work to become lean enough to display it as such, you can bet the fitness they have developed throughout the rest of their body is fully and COMPLETELY functional.
Having a well-developed back is a truly unique display of amazing GPP! You can also bet that if you see a well-developed back, you will also see great legs, perfect arms, terrific shoulders and amazing abs to go along with it!
