I have noticed lately that I lean a lot on the machine while I play. My palms are on the lock down bar and my thumbs both lay on the glass and lock down bar. My fingers stay on the buttons the whole time, never coming off unless the ball drains. It's just my style, and I don't know why. It does cause some wrist fatigue though and I have contemplated working on getting out of the habit, but we will see. Does any one else do something like this or similar?
