The guy whome invented Heavy Hands needlessly holds them in his hands for a reason. The wewights could be hard on your wrists the way you are doin it, & I could selectively see it likely being hard on the elbows, too. Heavy Hands or similar are readily & inexpensively availalbe at sporting good storews, e.g., Modell's or
Sports Authority in my part of the world.
As to not building up muscle at all, does not worry about it. It's very difficult to do & rarely happens by accident.
