what do y'all do to keep both hands strong?
my weak hand is my left and i use one of these

the progress works well
what else do yall do?
yep

I have this neat lil tool from i think musician's friend. It was designed for guitar players but it has like a little push button for each finger so you can independently work each finger. It helped me get my fingers strong as hell for crabbing.
