The person here say's his 13 year old nephew can't insert his thumb all the way into the thumb hole.
This photo as he puts it shows.
"photo is how far his thumb can get into hole, with fingers fully inserted into grip - in this one notice extreme negative angle, and his thumb can only reach 80% into the thumb hole. "
My thought here is the way the hand is positioned with the wrist bent back is pulling the thumb out of the hole not that the span is long.
here
"Photo of fingers over holes, shows just makes it past hole used to fit the grips in. His fingers not stretched, but absolutely not contracted. Normal, relaxed as should be. "
Here it's said that the span is too long because the first joint is at the edge of the hole.
He Feels the span is about 1/2" too long and should look like this photo from ron cliftons site. and span check.
You can check your own span to see if it is in the “safe zone†by following these easy steps. (If you wear a wrist brace always make sure it is on when checking your span.)
1. Locate the two creases at your finger joints and mark a line in the middle between the two as shown in photo.
2. Set your ball on a table, fully insert your thumb and lay your fingers across the holes and stretch them pretty taught, then relax the hand.
3. Once the hand is relaxed the line you drew between the two creases should fall within one eighth of an inch to the edge of each fingerhole.
Any thoughts?
