Kriek on what it takes to produce results.
Learn something from this article. He reiterates that hard work and motivation is still the primary element in success on the court. Other factors include technical aspects of coaching and learning and this is where a good coach with knowledge of technique can shorten the time needed on the court to master a skill.
I totally agree with this approach on technique. It can shorten years of practice and training to just simply have proper form within the boundaries of physics and biomechanics. Not everyone has to look the same but the laws of physics and human anatomy dictate certain approaches for good results. The upside gain for proper technique is that your ability to improve your results has more to do with your physical abilities once you achieve proper form.
Control first, and power last.
