I've been working out with Jonathon for over 13 years, and I can honestly say it's been one of the best investments I've made in myself. He helped me get into the best shape of my life, and I actually continue reaching goal after goal that I wasn't sure I could hit. As I evolve, he evolves. I need that consistency and accountability to be successful. Everything is personalized. Strength training during our session together, and then he sets me up with a clear plan for cardio and nutrition that I follow on my own. Jonathon is someone who truly understands how to build a plan that fits your life and gets results. I also appreciate that it's not just a gym. I've made connections and friendships with really great people. If you're looking for someone who knows what they're doing and genuinely cares about helping you reach your goals, I can't recommend him enough.

Jonathon is a wonderful personal trainer! When I first decided to hire a trainer in 2014, I was just about to have a BIG birthday and feeling out of shape and flabby. Jonathan inspired me to pursue my goal of being in a body building competition. I thought I was too old but I'll never forget when he said that doesn't matter as long as you're the best that you can be. Within a short time I had lost 20 lbs and was on stage in a bikini. He helped me totally transform my body! To this day I always remember that and his belief in me is what inspires me to be the best I can be no matter the challenge. Jonathan is just the right mixture of sweet and tough! All of his clients are amazing, friendly and loyal people who are fun to work out with. It's rare today to find someone who really cares and encourages like Jonathan.

Four years ago, my cardio was poor because I suffer from exercise-induced asthma, and my back would hurt on and off due to three lumbosacral hernias. I joined Jonathon's gym because I needed a structured training program to strengthen my back. Jonathon customized my lifting program to fit my needs, set up a meal plan to support my training, and recommended adding running to improve my cardio. I followed his advice exactly. I have not had another asthma flare-up related to exercise. My squat increased to a maximum of 210 pounds, and I went from experiencing pain during fast walks to running a 5K, a 10K, two half marathons, a sprint triathlon, a marathon, and a 50K ultramarathon, without ever experiencing back pain again. I truly do not have enough words to thank Jonathon for the impact he has had on my health and my life.

I've been training with Jonathon at Lonestar Fitness since 2017, and I can honestly say he's one of the best! He's knowledgeable, motivating, and truly cares about his clients' progress and well-being. Jonathon knows how to push you just enough while still making workouts enjoyable! I've seen real results over the years and feel stronger and healthier because of his guidance. If you're looking for a trainer who is consistent, encouraging, and genuinely interested in your success, I can't recommend Jonathan enough!

Working with Jonathon over the past two years has completely changed my relationship with fitness. I started training with him postpartum feeling overwhelmed and unsure where to begin, and with his guidance I've lost weight, gained muscle, and regained confidence in my body. What sets Jonathon apart is the accountability and support he provides. He helped me understand nutrition and gave me a clear, sustainable plan for weight loss, which made all the difference. I'm stronger, healthier, and more confident than I've been in years, and I'm so grateful for his coaching.

Client testimony

I have worked out with Jonathan since 2012 and have gone through many life changes throughout that time. Jonathan was always there encouraging me when I needed it and pushing me when I didn't want to be there. He has celebrated wins and mourned losses. I am beyond grateful for the gym community he has created and feel supported each week.

As someone who has been training with Jonathon for 10+ years, I cannot recommend working out at Lonestar Fitness enough. Jonathon creates a gym environment comfortable for all fitness levels and provides no nonsense, results driven training. Jonathon has helped me train for everything, from a career in law enforcement to looking good in my wedding dress. He is knowledgeable, honest, and personable. It has always been impossible for me to not see results when following his meal and workout plans consistently. Jonathon's approach is truly what functional fitness is all about.

I have trained with Jonathon Pirpich for approximately 15 years, and I cannot recommend him highly enough. He is knowledgeable, motivating, and knows exactly how to challenge and support you based on your individual needs and ability level. He truly cares about your health, fitness, and overall well-being, and that makes all the difference.

I was 47 when I came to grips that what I was doing with my health wasn't working. In spite of my own efforts, my strength, endurance, and body composition weren't where I wanted them to be. Any trainer I wanted to invest my time and money with had better personally demonstrate the results I was looking for. Jonathon Pirpich made it on that much shorter list. Jonathon runs a simple methodology of strength training, cardio, and diet that produces results in line with your specific goals. Implementing his training over time has put me in the best shape of my life. If the status quo is no longer for you and if you're willing to put in the effort, Jonathon produces extraordinary results. He is highly recommended.

Client testimony

I've worked with 5 personal trainers throughout my life, but Jonathan's the best! Structured a plan that works and knows how to adapt when necessary. There is no one size fits all. Jonathan recognizes each client's expectations and goals and works with you accordingly! Can't recommend him enough!

I've trained my whole life and have always loved staying active, but Jonathan is the first trainer who truly helped me achieve the body transformation I had been hoping for. He took the time to understand my goals, guided me with both workouts and nutrition, and stayed invested in my progress every step of the way. What means even more to me is that he helped keep me strong so I can continue doing the things I love at this stage in life: hiking, waterskiing, snow skiing, and staying active in general. If you want real results, Jonathan is the trainer you want.

Laurie Jones

Client testimony

Jonathan does a fantastic job of working with you to meet your personal goals. He takes each of his clients' bodies and customizes a workout to benefit their specific needs while assuring a safe workout. Both my husband and I have found his training to be helpful and motivating for us as we are working towards our health goals.

Jonathan is by far the best trainer around. Lost 20lb and put on a ton of muscle without even thinking about the workouts. He did everything for me. If you are looking for a 1:1 experience for a price cheaper than most gyms, go here. You won't regret it.
