bens back

charlie, what did you have ben do for his back? did you specifically focus on this area or is that just genetics mainly?

he did deadlifts early in his career I believe. That would put some meat on your traps and erectors

the lat pull downs as well, and his explosive start probably worked his back quite well.

For the spinal erectors: Gleut-ham Raises; Reverse Hypers; Squats etc

Did he ever do side bridges? Does anyone else incorporate this exercise into their routine?
