As an experienced professional instructor, I've heard tons of students say to me, "I've practiced the putting changes you've requested... however they haven't made me a better putter on the golf course, in fact I'm putting worse" - the problem is unsupervised practice sessions!
Let's face it, practicing the grip, stance, and alignment are solid
fundamentals but normally aren't the source of poor putting -
most of the time!
Ask your student's how they verify the following
skills when they're practicing on the putting green without you:
(1) How do you verify club face alignment & ball speed at the cup?
(2) How do you practice face angle relationship to the stroke's path?
(3) How do you practice putting with a rhythmical putting stroke.
(4) How do you verify & evaluate why you miss putts - that seem easy?
The fact of the matter is: technology shortens the learning curve! That's why videoing the FULL SWING has made it easier to learn how
to get the ball into the air with consistency for most players.
The Nside10 ProStrokeTM teaches the "nuances of putting" using the
verification of alignment relative to the intended starting line of the
putt and then teaches the players how to develop a smooth putting
stroke that will return the face angle to the ball consistently.
