Hi there, I’m Kate Young and I’m a fitness coach from California, but I now live in Austin. I have been involved in so many different sports over the years, including swimming, running, athletics, gymnastics, rugby (yeas, you read that right), baseball, tennis, and so many more that I have lost count.

I just love competing in sports, but struggled to find the one that I would stick with. So, instead I decided to become a fitness coach as it allows me to work with so many different types of athletes.

I’ve also become heavily involved it diet. The reason for this is that I’ve seen too many athletes fail in their fitness goals because their diet didn’t support it. And I’ve seen just as many people fail in their diets, because their fitness activities weren’t effective.

A lot of my work has involved working up with college tennis teams where I have tailored some endurance type fitness programs. Tennis coaches are great at teaching techniques, but a lot of them struggle with general fitness levels.

And that’s where I come in. On this site I contribute to anything tennis, fitness and diet related, which will help you get to your goals quicker and with more ease. And if you have some very specific questions then why not reach out on one of the social media channels where all of us are very active.

We will be happy to hear your thoughts
