Flexibility versus release style CF versus CP?

[ddono]

I think I read one of Dr Mann’s papers that says CP style release requires more flexibility than a CF style.  Wondering what specific flexibility in what area of the body we are talking about? Are there any exercises you can do to improve flexibility in those spots? Is it the same area’s in the CF release and it just does not require as much range of motion or is it totally different spots of flexibility required for a CF release?  I’m working on a CF style release so most interested in flexibility requirements and improvement exercise for that style release.

To perform a CP-arm release requires a far more open pelvis/upper torso alignment through impact and that requires a greater degree of hip joint and spinal flexibility.

Here is Tiger Woods performing a CF-arm release action in his driver swing action.

Note that he is not opening his pelvis/uppper torso that much through impact and his hands are moving targetwards, and not inside-left, in his early followthrough.

Here is Tiger Woods performing a CP-arm release action using a short iron.

Note how open his pelvis/upper torso alignment is during his followthrough.

Many pro golfers have the flexibility to perform a CP-arm release action with their short-mid irons, but not for their driver swings and fairway woods.

The disadvantage of a CF-arm release action is that it is not possible to perform a no-roll subtype of DH-hand release action through impact, and one has to use a full-roll hand subtype of DH-release action, which is dependent on the timing/speed of external rotation of the lead humerus through impact. A full-roll hand release action can cause excessive clubface roll between P7 => P7.2 if the lead forearm supinates excessively during that time period, and that can result in a non-DH hand release action, which is more timing-dependent.

Thank you for the explanation. Any excercises you would suggest to improve flexibility in those area’s?

I am not an expert on exercises for increasing spinal and hip joint flexibility. However, commonsense dictates that working with a torso-rotation gym machine, or cable-crossing techniques, or throwing a heavy medicine ball may be helpful. I use the term "may be helpful" because it didn't help me. I have a fused spine and near-zero hula hula flexibility and years of trying these exercises have not benefited me.
