About PK

The orginal idea of Thor Strength began in 2014. I began by coaching fellow classmates in college. After college, I went to go work in the Bahamas as a divemaster for a year. While there, I built a gym on the beach for my coworkers and guests to use with a manual for all possible exercises and tutorials. I returned home to New York and jumped into helping open an Anytime Fitness. I was in charge of everything personal training. I always wanted to be able to coach, but now I saw how to run a facility, and this became my next obsession. After two years, my wife and I decided that we wanted to leave New York and settle down somewhere else. We decided on Denver and I had one plan; to open my own gym. It took me about 2 years of working at VASA Fitness before I decided to move on and rent out space from a smaller gym. I had enough clients to support myself, but I wanted to provide my clients a safe space. A year went by and then the pandemic. Fortunately, we bought a house right before. I managed to buy all the equipment I would need to continue coaching. Our garage became a gym and my clients continued to train. We thrived in a tiny 1 car garage; so much so that it became apparent that we would need to scale up. And thus, in April 2021, Thor Strength was born. It's been a journey, and I appreciate all of my clients who stuck with me through the whole process. I'm happy that we have a home and I'm excited to share it with like-minded individuals.

My favorite client story

Everyone has a story to tell after some time. I've had clients say that they can get out of the car without pain anymore. Others say that they no longer need help picking up their dog food and taking it to their car.

My favorite exercise

Currently: Squats

My favorite quote

Currently: "Everyone wants to eat, but no one wants to hunt"

My training philosophy

The main component of my coaching is getting YOU stronger. Strength is the key for me. Through this approach, I like to add core stability work, mobility drills as well as general physical preparedness (GPP) exercises.

My training experience

I've been coaching since 2014. I've worked with people ages 13-87, and everyone has gotten stronger. I've worked with clients with various shoulder, hip, knee and back issues.

I've also been a competitive strongman since 2016. As well as a powerlifter since 2019. I hold several New York and Colorado state records in both sports as well as one national record in strongman.
