Re: Straight arm pullover technique???
Hey Thom, I totally agree with you. There are some exercises some people just like to do. They just feel good for some reason and the person simply has fun doing them. So unless that exercise is counterproductive to ones goals, or injurious, why not do it?
But you’re also quite correct in that at the end of the day, only science will be able to answer what actual practical or performance utility an exercise may hold.

Gee – don’t you think that would have got changed in the IAWA(UK) rulebook by now???????
Al, you’re the IAWA Prez…make it happen.

Jim, you also need to consider your unique levers and what role they play in executing this, or any exercise. While too much flexibility reduces everybody’s strength potential, this might not manifest itself in all people equally due to several issues, one of which being anthropometrics, or the type of exercise, etc. That’s the prime reason why it’s silly to do what Larry Scott did, or Cyr, and expect to reach ones potential. Only a scientific and controlled study can show if Scott, Cyr, et al. were on the right track or not…and what will propel everybody’s performance to the next level. Since back then there was no such thing as exercise science, and since those guys just made guesses based on their unique genetic predispositions, it comes as no surprise that all of this “wisdom” we read about in Strength & Health, Iron Man, etc., and, sadly, even most publications today, is essentially nonsense.
The point is, Jim, with less shoulder flexibility you’d do even better in this exercise. But that might limit your performance in other exercises. So as always, it comes down to matters of peak performance and making choices.
