Scap pinch not released as prescribed by a hero out there would lock the elbow to the rib cage.

You can move one without moving the other.
There is a reason why he can't produce a barrel path match. He nor any student of his, nor TDS's, nor anyone promoting BB/A$$, have ever matched the high level barrel path.
Guess what....neither has anyone else on the internet except HI.com.
How's it working for you? You continually take advice from those who have never produced. You continue to take advice from people so ashamed of their work that they will not show it.
Your clock is ticking away. You will realize your ignorance some day.
IT IS IMPOSSIBLE FOR BB/A$$ TO PRODUCE THE HIGH LEVEL BARREL PATH.
IMPOSSIBLE
When....will you ask for confirmation of their theory?
When....will you ask for video of their work?
BB/A$$ side by side against a high level hitter.....Buttherface, TDS, Noontime.....the rest.....will be exposed.
THE REASON......WHY.....THEY CAN"T PRODUCE A VIDEO MATCH.....IS.....
You can't produce a match using both legs. You can't produce the depth of barrel speed that is seen in all high level hitters.....when weight is shifted forward to the lead leg. The lead leg is worthless unless it has accepted some weight. Accepting weight AUTOMATICALLY eliminates the high level barrel path.
FACT.
Go ahead....ask them for video of their work.
Can't wait to be proven right.....again.
Above is the best they can do.
She unloads her scap to push her barrel forward. Her rear hip/leg PUSH the barrel because she is two legged.
The result is an out front forward push of the barrel as she turns it. Very amateurish.
