Goblet squat is difficult with smart handle.

Of the exercises in tonal I find goblet squat and anything else where you grip the handle with both hands, to be very bad ergonomically. I can't always get a good grip on the tiny handle with both hands (I have pretty big hands that span about 12 keys on the piano). I guess I could use the rope for this but I always found the rope dubious as it's just balls on the end, I'm afraid it would slip. And the bar, yes it would work....but then I'm basically doing a different exercise at that point.

Anyone have a suggestion on how I can more comfortably do goblet squats and similar for my big hands?
