Ray Heiser

I'm a certified personal trainer in San Angelo, TX, Navy veteran, and competitive powerlifter with over 10 years of experience in strength training and conditioning. My coaching combines military discipline, functional strength training, and advanced powerlifting methods to help athletes and everyday people get stronger, move better, and transform their lives.

My Background

My journey began as a Navy Seabee, where discipline, grit, and physical resilience were daily requirements. After serving five years, I transitioned into civilian life and continued my passion for strength training and powerlifting, competing at both the national and local levels.

I’ve earned 1st place at the Military & First Responder Nationals (2023) and competed at Collegiate Nationals (2025), giving me first-hand experience in elite-level competition and performance coaching.

Coaching Experience

While studying Natural Resource Management at Angelo State University, I also serve as Ram Powerlifting President. Coaching one of my athletes to the national level showed me how much I love educating, guiding, and pushing others to reach their goals.

At West Texas Strength in San Angelo, I specialize in:

Personal training for beginners looking to build confidence in the gym.

Powerlifting coaching for athletes preparing for competition.

Strength training for martial artists to develop explosive power for striking and grappling.

Fat loss and conditioning programs are designed to improve strength, endurance, and body composition.

Why Train With Me?

I bring a unique style of coaching that blends military discipline, competitive powerlifting expertise, and a focus on safe and efficient long-term progress. Whether you’re new to fitness, an athlete, or someone looking to take their training to the next level, I’ll help you unlock your potential.

Abby Rollwitz

I’m Abby, an ISSA-certified personal trainer based in San Angelo, TX, and I’m on a mission to help you stop feeling out of place and start owning your space in the gym. I know exactly how intimidating it is to walk in not knowing what you’re doing—because I’ve been that girl. That’s why my coaching is built around real education, real encouragement, and stacking small wins that actually last.

My journey has never been black and white. But everything changed when I stopped putting myself last. Choosing to prioritize my health didn’t just change how I looked—it changed how I show up in every area of my life.

It didn’t start perfectly. It started small—tweaking my routine, hiring a coach, and learning the basics of nutrition and movement. That consistency built confidence, and that confidence turned into purpose.

At West Texas Strength, I specialize in:

Strength training and gym confidence

Fat loss and sustainable body recomposition coaching

Fat loss and sustainable body recomposition coaching

Training focused on form, education, and progression

Building consistency, discipline, and long-term healthy habits

Why work with Abby?

Because I know what it feels like to walk into a gym and feel completely lost.

I don’t just give you a workout plan and send you on your way—I teach you how to train, how to fuel your body, and how to actually build confidence inside the gym. My approach is simple: no overwhelm, no guessing, and no all-or-nothing mindset.

My job is to take that pressure off you and replace it with structure, education, and small wins you can actually build on.

If you’re ready to stop starting over and finally start building something sustainable, I’m here for that.
