Jim, I had a very weak serve despite having taken lessons for more than twenty years, and having read many tennis books. They had told me stay loose, keep my elbow high, bend my knees etc, but nothing seemed to help. So when I saw an announcement about MTKS in Brent Abel's website, I jumped on it. I must say that watching videos has been much more effective for me than taking lessons. While studying your material I had several "Aha!" moments.

It has taken perseverance and hard work, and my serve is still a work in progress, but now I routinely hit kick serves to both sides of the court. Now I win points just by kicking it to the ad court. I am still amazed when I see the ball curve down, hit the sideline and kick to my opponent's backhand. My serve is not a liability anymore, and I enjoy each time that I hit a kicker.

Thank you, it has been a great learning experience.

Jim -- at the start of this new year, I'd like to thank-you for all of the great online instruction you have provided. MTKS and Building the Serve from the Ground Up have both been instrumental in turning my former weakness into a "partial" weapon. I say 'partial' because I am still working on this most important stroke. It takes time and patience. Your online instruction is clear and precise. I continue to gradually improve and my hitting partners all notice a big difference in the quality of my serve over the past several months. I also thank you for the timely and constructive feedback after I upload my serve videos. The serve is so, so important and I look forward to further 'tinkering' my service motion under your thoughtful guidance. Thank-you for opening my eyes and guiding me on this fun journey of self-discovery!

I’ve signed up for two other on-line tennis “courses” in the past and Mr. McLennan’s was decidedly the best. Unique, concise and genuinely helpful

Incidentally, your MTKS lessons have increased my first serve percentages to levels that didn’t seem possible. I use this serve nearly exclusively for both the first and second serve. You have helped me turn my weakest part of my game into a weapon. Your other video regarding hitting up on the ball with a throwing motion has really put some pace on my serve and has made it much more unpredictable for my opponents. I purchased another service video from a competitor, but your videos have been THE most helpful from the very outset. I don’t regret a dime I spent for your video instruction. I’m 66 years old and have never enjoyed the game more. I’m consistent, confident, and composed when serving now and that confidence has upped my game in other areas as well, thanks to you.

At the time I first tried Building the Serve, I was a man with decent second serves. After two days intensive work on this course, I had discovered a first serve. At the time is was a revelation; so much power with so little effort. Today, two years later, I’ve been using exercises from this course to refine parts of my serve and remind my body how to let it happen. This is the basis from which all my serve understanding is built. Truly excellent.

Jim, The material is absolutely great I hesitate to write in because deep down I don’t want other players finding out how good it is (LOL ) each time I go out to practice I remember the tips or videos , the hot seat is fantastic, I’m still trying to figure out how to take and send in a video. MY GAME HAS DEFINITELY IMPROVED I now have confidence in my serve, I don’t worry about double faults, because I’m to busy trying to see which way the ball is spinning (lol).

- Jack Phifer, Brownsville, Texas

I have been following your excellent instruction. As one of the few master instructors found online, you consistently simplify the complex for your followers. I hope they appreciate the tens of thousands of hours and years you have devoted to your expertise…it shows! Your site is one of only a handful that I will confidently send my students and online followers to for the fundamentals of the game…

- Scott Harper

You’ve proven that it is possible to use internet learning to teach tennis in such a careful, attention-to-detail, three-dimensional way that improvement is possible with the proper amount of ‘study’ and practice. Your approach has broken new ground and set a standard that will not be easy to copy…You’ve given this senior tennis player new skills and a welcome new involvement in the game.

I tried the serve in the box exercise and both my cousin and I were amazed at the instant improvement. I got 10 out of 10 serves in instantly without much effort.

Jim, your serving program has quickly made a change in the quality and consistency of my serves while helping me avoid stress on my shoulder. I don’t own it yet, but I expect to do soon. I think the Key Sequential Elements and On Court Exercises are especially helpful. I have been impressed with the very good work you have done in all elements of your tennis instruction. Please continue!

I have been anxiously waiting for this course about the backhand.

I love my one-hander, but somehow it takes me so long, years, to brush it up and forge… It still lacks consistency and is used more as a versatile defensive tool… I am determined to perfect it into a weapon now that I have access to your material.

Your instructions are always so thoughtful and clear, they work like magic for our amateur minds and bodies making them “click” right away. Thank you

- Tatiana, Moscow, Russia

I’m one of those players who’s 1 handed backhand had always been more consistent and controlled than his forehand, but it was a slice, lacking real power with heavy under spin.

With a few adjustments to grip, swing path and wrist involvement; you’ve helped me develop the “sting & drive” shots turning my 1 hander into a real weapon.

Thanks Coach, the results you helped me create have again exceeded my expectations and will keep me coming back for more.

- Jeff Sandler, Cherry Hill, NJ

Great presentation, it has helped my backhand no end. My backhand is still a work in progress but with your instruction I have made a big improvement, especially with the slice backhand. It is good that I can come back and review your instructions and watch the videos and get back to basics.

Also I have to say a big thank you for the instruction that you gave on the second serve. Was able to follow the instructions and have incorporated that serve into my game. Its great to throw in as first serve every now and again.

- Graham Barry, Ireland

The format of the Streamlining was excellent- very easy to follow in sequence. I enjoyed the concept of comparing throwing a ball with the motion of the tennis stroke whether in the forehand or service motion. Well done.

- Dr William Baron, Rockaway, NJ

I have struggled with my weak serve for decades. This is now the first time ever that I feel confident when I stand up at the serve line. I am winning many more serve games than before.

- Felix Fernandez, Glen Mills, PA

I've been following Jim's work for a few years. His dialogue about tennis and learning about tennis is beyond comparison. His ideas, knowledge, and story telling is unimaginable. You have to follow this master teacher. His gems. of wisdom will lift your game to the next level without doubt.

The material is highly educational, thought out and well written, I look forward to his articles, podcasts, everyday. I know I'm a better person and grown as a player, competitor, along the journey.

Hi Jim, the Mastering The Ground Game is excellent. It is true, that I was expecting something different. But I have to admit, that my forehand now is much better. There are several reasons for that. First I m waiting the ball on the back foot (even if my serve return is now better) a the second mistake was I was pulling my shoulder ahead too early. And the third thing I turn my grip from eastern forehand to the semi western – these grip is very good for the really, but I have got problems with lower or sliced balls – i have to work on it. There are a lot of things on my forehand side which could be better.

- Jiri Kovar, Czech Republik

I found the lesson about moving in two’s especially helpful. I realized that I had been hitting many shots off balance. Just concentrating on not shifting my weight forward too quickly (when I am able to actually do it) has me hitting better, more consistent ground strokes and even helps with power on the serve. While I have not mastered any of the fundamentals in this course, just the thought I should maintain better balance has helped my strokes.

- Harold Johnson, Macon, Georgia

Jim’s prioritizing the components of the ground strokes from the core to the periphery is an astounding truth, in my opinion, that was rarely heard of from other coaches in my experience. The 1, 2 rhythm really works, it provides a dynamic balance for my body before the hit. With the 1,2 rhythm I can improvise with my hand more than if I am not using this amazing yet simple concept. Also, Jim, your matching the grip with the appropriate contact point is an eye opener – I never heard of it anywhere else, well, maybe I have been ignorant. Great product.
