As is my custom with the fitness pioneers, the more the responsibility entrusted to me increases, I turn after God to the fitness pioneers to find what I need in their courses, lecturers, and scientific material. All thanks, all appreciation to Dr. Osama Mahran for the most wonderful course, from which we emerged with large amounts of information. Which has greatly benefited us on the practical and personal level. It corrected for us concepts that had been stuck in our minds for a long time. We thank you for your generosity in answering all our questions. We thank you for your ability to conduct the lecture without getting bored. For your creativity in conveying the information smoothly. We do not fulfill your destiny, our sincere heartfelt wishes for success and good luck, and that your efforts with us will bear fruit and we will achieve our highest hopes in this specialization that is very much needed in the sports arena today.
