About Us

I am the founder of Strength and Endurance Academy. I’ve helped many people loose weight, gain muscle and live a healthy balanced lifestyle. Fitness has always been apart of my life. It has always been there for me through the hardest times. Fitness guided me into a healthy life physically, emotionally and mentally then I knew that this is something I wanted to do for the rest of my life. I wanted to help others turn to fitness as a stress reliever and more! I love what I do and I enjoy making an impact in people’s lives.

I started my fitness journey 2 years ago and fell in love with it! I love helping others and pushing them to achieve greatness. Fitness is something I can turn to, to overcome obstacles in life. I love learning the fundamentals of working out and how the body works. With this knowledge I’ve gained for the past years I use it to help individuals transform.

I am a Fitness Instructor/Personal Trainer at Strength and Endurance Academy. With over 15 years of Combat Sports experience, I am an accomplished competitor, and I enjoy using my skills to contribute to the exciting advances that happen every day at S&E. I graduated from the University of Texas at San Antonio in 2020 with a bachelor's degree in Kinesiology. While in school, I competed in the Golden Gloves Boxing tournament where I finished 2nd. I currently live in Kyle, TX, and am available for Personal Training inquiries. 

Hello My name is Tony Islas.

I joined a CrossFit gym I’m 2014, and became a L1 Certified Coach in 2016.

I love coaching and helping people reach their goals. There is no better feeling than to watch a member reach there goals by putting in the work and seeing it pay off. I’m a Husband, Father, Grandpa(Pappy) and a Veteran. I also teach people how to Hunt and Fish. Very excited to be a part of this Team and Community. 

For me, Fitness equates to

longevity and the chance to enjoy my

Health well into the later years of my life.

My experience at S&E has been fantastic.

The atmosphere is extremely friendly.

The team here has been nothing but welcoming and I appreciate their business model and how it involves the community.

Fitness for me is about longevity  more than appearance. It’s nice to look good but it’s more about feeling great at the end of every day.

Being a part of the S&E team has been rewarding. Being around those who get after it everyday is extremely motivating. 

Fitness means taking care of myself physically but also mentally. It’s something I enjoy doing every day, even if it’s only for 30 minutes. I’ve been seeing changes in myself within the last 2.5 years but in the best ways and it’s something I will continue doing.

Being a part of the S&E team has brought me joy. It’s amazing to see how far the business has come but also the team, we are constantly growing together and supporting one another. I’m grateful to be a part of a community and team that wants what’s best for one another. 

Being apart of S&E since day one has not only been an incredible journey to watch but also a learning experience. Over the years I have been able to witness the amount of dedication and discipline one must have in order to accomplish your dreams. Being apart of such a devoted, dedicated, and disciplined team has drastically changed my lifestyle in the best way possible.

To me fitness goes beyond the physical aspect. It’s your mind and body connecting. Fitness is a healthy lifestyle that goes beyond just being “fit”, it is your mental well-being as well. Taking care of yourself and putting yourself first.  

S&E has helped me stay focused both in and out of the gym.
