“I have been training under PK for over a year now. I’ve always been uncomfortable with my body and always thought I could never strengthen it. Not only does PK make me feel comfortable with my body but he is also my biggest advocate on being healthier and stronger. I have seen such a huge difference in my strength in the past year and I’m excited for many more! I love working with PK so much that I take a 30 mile commute just to have a session together because his coaching is 1000000% worth it!”

“I would highly recommend PK Thorstenn as a personal trainer and strength coach. PK did an expert job preparing me for a recent powerlifting event. I not only won my age group, but also bested five competitors in the “Open” division in the bench press. PK’s instruction was well-suited for my style and I could not have done as well without his support and training".”

“My wife and I have been working with PK for a while now. PK is very knowledgeable and personable and his passion shows through in both of these aspects. Not only has he shown me where I can improve in my lifting and my form but he has also given me specific stretches and exercises that help me make further improvements. Whether you are new to exercise or have been doing it for a while, I highly recommend PK to get you going in the right direction.”
