I personally wouldn’t treat them differently. The goal is to get everyone, no matter how untalented, to run with the optimal mechanics. I would actually think that the less talented athlete would have a harder time pulling than the more talented athlete (even if that’s what you coached them to do). Ralph Mann’s research suggests that only the very, very elite of the elite do what can be considered a pre-contact pull. The slower athlete just wouldn’t be wired to switch quickly enough from hip flexion to hip extension to benefit.
RE: the pawback vs catch and push in TJ…if you talk to the expert proponents of the seemingly opposing views you realize that much of the difference is semantical / conceptual rather than a differing of technique.
