Yes, I was going to ask if he is cutting back on the weights, sometimes those muscles just get too big for the natural body type and close down the spaces needed for nerves and blood flow.
I don't know how bulked he might be in comparison to his before or normal body type.. but sometimes general overall fitness is better than over doing weights & bulking up.
And firefighting is a strenuous thing too the equipment heavy gear, hoses ..
He doesn't want to risk long term problems or at worst case extreme symptoms /pain, so please ask him to consider stopping weights for now..
We have had many lifters join this last year, so i think they will agree, it's not worth the risk.
Also read thru the sticky threads for a crash course on TOS & similar injuries/conditions.
