Start out by placing one penny coin on the back of the hand.
The coin is tossed about 30 centimeters into the air and snatched when it is at eye level.
Move onto 2 coins and then onto 3.
Spend a few minutes on each hand each day.
You will need to spend a bit of time learning to do this at first but once learnt, just spend 2 minutes on each hand each day.
