Rarefied Tennis

Tennis can be a very frustrating sport if you can’t improve. Is it a physical issue or a fundamental one. Maybe it’s just mental? Of course it has to be some sort of reason. It is known that tennis is a very fundamental sport if you want to be good, or for that matter, just want to keep improving. I’ve always asked players of all levels, if you had fundamentals like a pro , would you be a better player? The answer was always “of course ,100%”. Without a doubt, if you can hit the ball harder and more consistent, you will enjoy your game more and of course be a better player. This is where we fit in!! The secret behind developing effortless fundamentals is basically known to only a select few. This is how we came up with our name Rarefied Tennis

Pros become pros because of how they can hit the ball. Most amateurs (pupils of the game) don’t believe they can hit the ball this way because they think it takes some sort of special ability to do so. Rubbish, anyone can do it, of course not with the same power and strength yet, but the fundamental part. The knowledge we give you here focuses on understanding the reasons why you haven’t been able to do it, recognizing the source of your problem is the key to improving. See what you have been missing in your game or fundamentals when you look closer into Rarefied Tennis, this is where “Truth and Honesty always wins”.
