This is my first time using Coach Up. I found it just by searching and playing around, but I did some research on it and it got good reviews. I then researched a number of coaches on the site and decided that Ken sounded like he is the right coach for me based upon his experience and the site reviews. I went with cautious optimism because I have worked with some good coaches and some bad coaches before. I'm not a great player, but know that it is possible for me to improve with the right coach.
I was very impressed with Ken. He is easy to talk to, and was very easy to work with. He started off with a warm up, which many coaches just skip over, probably figuring that you want to get in all of the time whacking the ball. Anyone who does that is not worth their salt because the warm-up is possibly one of the most important parts of the lesson.
After the warm up, we talked for a few minutes about my level of experience, my goals and what I felt were my weaknesses. We started working on backhand and I could see and feel improvement right off. Also, he was the first coach out of many who told me that the racquet I am using has too wide a grip for my hand. I researched the issue further (a bad habit of mine) and he's right. Ironically, I had bought the racquet from a previous coach who thought the racquet would be perfect for me.
The lesson was an hour, but I have to tell you that Ken was not looking to skimp on the time. I got there a little early and he was ready, so we started early and went up to and slightly over time until his next lesson arrived. He even commented that he does not worry about this as he will make up the additional time with his next lesson as well. I think it's nice that he was not nickel-and-dime'ing on the time as many other coaches do.
The only thing I think I might have done differently is that if I were evaluating someone, I probably would have spent a little more time evaluating during the first lesson the student's areas of weakness overall - kind of testing out all areas of play. But that's really a matter of personal style. I expect he is assuming (accurately so) that we will have other lessons where we can address other areas of play, and he preferred to spend time getting right to working on an area of weakness rather than simply evaluating everything at once.
I definitely recommend Ken as a coach - I don't think you will be disappointed.
