I started bowling last fall and I have a weak arm and wrist, too. I'm using a 15 lb (like my ball) dumbbell and I always bowl a few games after I get tired just to build up strength and endurance. Bowling 5-10 games on Saturday (unlimited games for $8

) makes my 3 games on Tuesday night league easy. My advice would simply be to bowl more. When I start to get tired, I bowl another 2 or 3 games. My scores are usually lower (or really high - go figure

) in those last games, but it has helped my arm strength a lot.
To you more experienced bowlers,
please tell me if this is not a good idea. I'd hate to be giving bad advice.
