About Us

This is about more than fitness.

It’s about freedom.

At Hardcor Fitness, we believe that training is about so much more than physical results. It’s about becoming the version of you who trusts yourself, with your body, your boundaries, your energy, your life.

We’re here because we’ve seen what happens when people are pushed into programs that don’t fit them.

We’ve lived the extremes. The burnout. The disordered patterns disguised as discipline.

So we created something different.

Something rooted in respect for the body, reverence for the process, and real coaching that doesn’t just get you results, it teaches you how and why.

We’re here to redefine what strength means.
To remind people they don’t have to punish themselves to feel powerful.
To hold space for transformation that actually sticks, because it was built on truth.

This work is our devotion.
It’s not just what we do.
It’s who we are.

Meet the Team

Cory Wiedeman

- Founder, Head Trainer

I’m a strength and athletic trainer with over a decade of experience and a B.S. in Kinesiology. My passion for fitness was born from healing—after overcoming a severe eating disorder, I discovered the power of movement and nourishment. Now, I help others do the same.

At Hardcor Fitness, we focus on sustainable results and real education. My goal is to equip you with the tools to thrive—long after our sessions end. Whether you're an athlete, managing a health condition, building muscle, or losing weight, I’m here to guide you with consistency, care, and a bit of fun.

Train with me in a private studio in San Diego and start seeing yourself in a whole new light.

Sonjia Escudero

- Assistant Trainer

With a B.S. in Kinesiology from SDSU and over 6 years in my own fitness journey, I bring a hybrid, well-rounded approach to training. From bodybuilding to my first half marathon, I blend functional, resistance, and endurance training to support a balanced lifestyle.

I believe fitness should support mental health, not compete with it. My mission is to help you grow stronger—physically and mentally—through personalized plans that meet you where you are and push you past your limits.

Let’s get you out of your comfort zone and into your power.

"Sonjia made working out so enjoyable! She's not only the sweetest human but also very knowledgeable and listened to what I was trying to achieve and helped me get there FAST. I was able to get wedding ready in 6 months (doing 2 sessions per week). I'm super happy with the results, I'm feeling more confident than ever, and it's all thanks to Sonjia. Could not recommend working with her enough!"
