Hello Mark, my 10 year old daughter Sophia has been taking your “100 MPH Serve Course. In less than a week her speed has increased 15 mph and she is very excited about your course and teachings. Thank You!"

I want to thank you for the serve course that you did this winter. It was a great course and many of my junior and adult players have benefited greatly from it over the last few months. Thank you for sharing your time and knowledge with everyone."

I want to thank Dr. Kovacs. I used to play US college tennis and I'm a tennis coach in Canada. Last week, I watched his video on practicing hitting serves off the back leg. I applied this to my serve and got immediate, amazing results. I added about 20-30 mph speed, more racquet speed, more spin, amazing consistency. All my life on my serve, as I tossed the ball up, I immediately leaned forward and hit off the front foot. My serve lacked consistency, spin, power and speed. For decades I examined my serve on video, trying to find the technical weakness. Now, taking Dr. Kovac's advice, jumping off the back leg, I feel the weight transfer, the coil, the loading and unloading, and explosion up and into the ball at impact. The difference in power and speed is staggering. (My coaches previously) never recognized this technical weakness and brought it to my attention. I would have been a much better player had they done so. Thank you Dr Kovacs. Not only do I now serve better, but I'll be a better coach and have my students realize the importance of coiling and loading off the back leg.”
