The Trailing Hand
Despite those labels, the trailing hand is the dominant hand for most people (if you play right-handed, your trailing, or bottom hand, will be your right hand).
It is important that the trailing hand is positioned in the golfer’s grip to deliver a powerful blow at impact without overpowering the lead (or top) hand. The hands must be equal partners in the grip; therefore their placement is vital for consistent ballstriking.
Identify the three sections of the ring, middle and index fingers (noted as sections 1, 2 and 3 in photo). Section 1 is the base of the finger (before the first knuckle), Section 3 is the tip of each finger (after the last knuckle) and Section 2 is in-between.
