I was always told that when doing finger pushups, you should spread your fingers on the floor, because doing them on your fingertips can ruin your vision, because there are meridians on your fingertips which are connected to your eyes. However, on the kung fu forum in the "figertraining question" thread, Drunken Monkey said that spreading your fingers puts too much pressure on your fingers, which can lead to tendonitis and arthritis. So what is the best way to do them? Thank you for any advice that you can give me on this topic
