I have always been a gym goer but the past couple years I have experimented with and practiced some kinds of non mainstream training. For example, neck training. No one wants to mess with the guy with a big neck. It is your shield, and together with the traps and shoulders it is your crown. It's a source of confidence and composure when you are under a bridge, along the dirty water, by yourself, on a warm moonlit night. Also grip strength. Yes I have gotten big into the v shaped grippers with the spring. But heavy ones for strength reps, like 150 and 200lbs. Grip strength is functional strength. Also grip can become a personality trait in difficult situations. Fishing is a tactical sport and grip strength can be very useful.
