[O.B.Left]

The shot put reminds me of Push Basic, but weird how we use it for very short, low powered shots and they use it for powering, thrusting, their heavy pay load. I guess you cant "swing" or "throw" that heavy an object. But I'd venture that Punch elbow, given its fanning is a throwing action and not an inline shot put like Push.

He mentions a firm left side too, but their feet are in the air at release. These track stars are all power and maybe more like the long drive guys than golfers who play for score.
