The tests on the first link look good.
Many golfers are probably trying to do things that their bodies will not, or do not want to do!!!
Our bodies are very good at finding a way to do what we ask. Unfortunately, in achieving a strenuous move like the golf stroke, forces may be re-directed to structures that cannot sustain the load.
I would encourage anyone who has the financial means to schedule time with a golf-specific trainer. The cost is similar to lessons from a golf professional, and like a good golf pro, they will be able to create a plan that is appropriate for you.
The trainer I am seeing is a physical therapist and 3.7 index player. My visits with him have made a huge impact on my physical condition and golf stroke (and my understanding of both).
