The ZenGrip is designed to be exceptionally easy to hold. In fact, it's about 10x easier to hold than traditional mugs. It is designed to redistribute the weight of the mug + liquid away from your fingers, thumb, or wrist. Instead, this weight is distributed to the larger, non-fatiguing muscles of the forearm.
For this reason, even with very weak hands, you should be able to hold the ZenGrip.
