When I was in film school at UCLA, long time ago, I used to treat handholding the same way I would a sport. When I played football I didn't expect to be able to not show up at practice and then just run on to the field and make great tackles. I would spend at least an hour every day practicing controlling my breathing and walking with my legs flexed to absorb shock. I did 50 pushups every day and worked with weights. I designed and built my own shoulder braces that fit my style of shooting. Still do, and I've been doing it for 40 years.
It amuses me that people just want to be able to pick up a camera and handhold like a pro - with no training or practice. Fine, get a lens with OIS, but I've seen plenty of examples of dreadful handholding even with it. The zoomy, jerky, tweaky stuff that shows up on TV is doing a real disservice to the true skill of being an operator.
