I read where the last three fingers were to be relaxed,but that is difficult to maintain a good grip. I have been working out with hand grippers and I am just starting to close the 100lb. grip-also with a finger gripmaster with 11 lbs. of pressure(plus some dumbells-they live next door). The last workout with the Bells caused pain in my shoulder(rotator? Deltoid? )I will try a solid grip as you recc. I am 68 - but never give up.>thanks>larry
