Does one have to be able to pass a TPI evaluation to be fit effectively for irons? I ask because it seems local TPI certified instructors insist on an evaluation first, then weeks of TPI workouts before getting to instruction or fitting. I am pretty good fitness-wise but was not able to do a full squat with a club over my head. Thus, I was given a TPI workout which has improved my abilities but as a Senior I am not sure I will ever be able to be as fit as a PGA Tour player. Any thoughts?
