Sentinel Performance Success Stories

Laura C. (Exercise Physiology / Cardiac Rehab), Sentinel Performance Testimonials

Having worked with Frank and Joe for the past couple of years, I am more pleased than ever as I continue to watch their wisdom and purposeful design play out on the race hill with my daughter, Brinn. As you may have read in Brinn’s up-date, this past ski season was a challenging one for her. Nevertheless, it was successful for the sole reason of the time that she had invested with Frank and Joe. Daily in the off-season she was dedicated to pursue what they asked of her without question. Their personally designed program inspired a purpose in her to which she was fully committed. The gains that she made with them are what carried her through this season. As an exercise physiologist, I trust my daughter’s training to no one else; they are simply the best.

Client Testimonial, Sentinel Performance Testimonials

When I first met Frank and Joe I was not very happy to see them. I knew I would be put through pain and doing something I did not want to do, exercise. But after a month or so of working with them, I had a change in heart , I decided that if I am going to have to show up and workout I should take this serious and not waste my time or theirs. The only way this was going to work is if I wanted it to put forth the effort. I told Frank and Joe that I was ready for this change and they were there with me every step of the way providing support. Unlike any other trainer they truly care about their clients. When their clients succeeds then they succeed, if their client fails then they fail. So, they put forth all of their effort into helping me change my way of life. With their help and expertise they have changed my way of life. Frank and Joe placed me on a diet plan that changed my life for the better. It changed my eating habits were I would choose healthier options and moderation. Then they changed my workout schedule. So instead of just working with them 3 days a week, I began to workout 7 days a week. 6 days of lifting or a circuit with cardio and then the 7th day of just cardio. They taught me an important life lesson from working out, I learned to be more disciplined in my way of life. Because of their effort, support, and encouragement, I have lost over a hundred pounds. I began at 355 and I am down to 229. I plan on continuing to lose weight with the support of Sentinel Performance. Dieting and exercise now has become a way of life for me.

Sharra C. (Fitness Competitor) , Sentinel Performance Testimonials

"At the beginning of my training, my one goal was to be able to do pull ups on my own, unassisted. Not only did I achieve my goal, but I surpassed it by a long shot. In 3.5 months with Sentinel Performance I transformed my body and my strength into the best condition I've ever been. Everyone's goals are different, but I've always wanted to be super strong for a girl. I started squatting and dead lifting with 95 lbs, and even that was a struggle. In a few short months with Sentinel I was squatting 225 lbs! I could go on and on about how wonderful they are as a trainer, and a mentors, but it's not necessary. Whatever your goals may be, Frank & Joe Gernetzke can help you attain your fitness aspirations. They offer online programs & diet plans, as well as one on one training. Check them out and let them help you start your journey today !"

Brinn C. (Junior Olympian Downhill Skier), Sentinel Performance Testimonials

February 19 - 22, 2014 - I am so pleased to announce that I made the Central / Rocky Division Junior Olympic Team! Thanks so much to God, my family, coaches, trainers, friends, and teachers; I wouldn't have made it without you!

April 2015 – I am excited to let everyone know that I once again made the Central / Rocky USSA Junior Olympic Team! Without a doubt, this year’s achievement would not have been possible without God, my family, private coach, trainers, friends, and teachers!

As most of you know, I have been training with Frank and Joe for over two years now, and Sentinel Performance has definitely been the key to my success. After my improvement and successful 2013-2014 season, I was determined to make additional gains this season; so Frank and Joe upped the ante last spring and put me to work. Last year I qualified for the Junior Olympic team in the top 25%, but I was determined to improve. With their help I was able to improve my ranking again by another 11 slots and medaled in slalom! I entered this season with more strength and power than I have ever had and anticipated great things. However, not everything went as smoothly as planned. My season this year was plagued with problems from never-ending equipment issues and faulty race boots to absentee coaches. For a significant number of my races, I stood barefoot in the snow until my feet went numb so that I could endure the pain of ill-fitting race boots and critiqued myself since no coach was available. Consequently, it is evident that my success was due solely to the strength and power that I had gained through training with Frank and Joe. Without the improvements I had made in the off-season using their purposefully designed program, this year most likely would have had a very different outcome. They were the key, and I could not have done it without them! I have already started post-season training and am ready to dive into my summer program knowing full well the importance of doing exactly what Frank and Joe ask of me and working as hard as they need me to. Their expertise has been proven once again, and I am extremely grateful they are in my corner.

The best gym experience I've ever had. Working out with Frank, Joe and Jihan has really changed the way I feel about training. I've dropped over 5% body fat and gained 10lbs of muscle while fitting into clothes I never thought I would again and feeling way more confident.

The personal care shown by each trainer and constant motivation to be better is something we all can use, and this is the place to get it.

Jen M. , Sentinel Performance Testimonials

For the 4 weeks I wasn’t exactly sure all training would entail.. I put my trust in Joe throughout the sessions and I was amazed at what the outcome. Having been part of this program taught me confidence and my capabilities of what my body can be trained to do. I appreciated his dedication to my training program ( although the latest in the day , on Monday). The sessions challenged me and I have continued to put to use what I learned. I was able to decrease a little weight which is stepping toward my goals!woo woo! Thanks for your patience, knowledge and guidance Joe! I look forward to another class session!!

Drake C. , Sentinel Performance Testimonials

I came to Sentinel Performance to make a change, because I couldn't make it by myself. I have very little drive, and I find myself failing pretty much at life. Frank and Joe changed that forever. I have spent 4 days a week for about 1 and a half months with Frank and Joe and I have lost over 25 lbs. I went from dead-lifting a bar with 5's on each side to dead-lifting 245 lbs. I encourage you to meet Frank and Joe, because they will change you, and they won't give up, no matter how long it takes or how long you complain. Trust me, you will complain a lot. My goal is to lose 45 lbs. by summer, and I am on the right path.

Leslie M. , Sentinel Performance Testimonials

Joe is the very first trainer I have not wanted to quit on. He is so inspiring and caring with his work out plans, and really strives for his clients to have proper form and knowledge as to what the exercises he has you perform are actually doing. His firm, but laid back, coaching style really works for me. Frank is a rock star as well. They each play off each other very well and have unique approaches that enable their clients to feel that they are both working for you, regardless of which one you are training with at the time. I've been working out with them for over 2 years and have seen awesome results. I was injured and weak when I started and now no longer have any back or knee pain. I highly recommend joining the Sentinel family :)

Sonia P. , Sentinel Performance Testimonials

As a long time athlete I have developed a cynicism for personal trainers. Far too often trainers use the same methods on every client, lack passion for total health and use intimidation to motivate. Sentinel Performance LLC is the complete opposite! Joe and Frank listen, modify and push you to reach personal goals in a healthy manner. My visit to their group session was fun, challenging and interactive. Even though it was a group workout, I still felt that I received individualized attention and look forward to returning to future sessions.

Heather N. , Sentinel Performance Testimonials

Until I started training with Frank I hated working out due to constant knee pain from an injury several years ago. Frank built a workout program specifically for me to regain my strength and to teach me proper form. Though I’ve only been part of Sentinel for a few months, both Frank and Joe have been extremely supportive, and I have made so much progress. I am pain free and able to compete in other activities I haven’t been able to do in years. I also enjoy going to the gym daily, something I never thought I would say. I highly recommend Sentinel Performance—they have changed my life and I cannot thank them enough.

I love this place! It's so NOT intimidating! The coaches are so unassuming! I recently had some rotten surgeries that really started making me feel wimpy and like I'm falling apart. Training here has built not only my strength but my confidence to try new things as well. Thanks Sentinel!

Robert P. , Sentinel Performance Testimonials

You can tell as soon as you walk in the door both Joe and Frank have a passion for fitness and training. While you are going through a session, it is very apparent that their passion is also backed by high intellect and precision of proper technique in order to maximize your fullest potential as a person. I would highly recommend anyone to get in touch with either Joe or Frank if they are looking for an individualized workout routine, group session, or just want to share the passion of training with two genuine guys.

Joe and Frank helped me get in amazing shape for my wedding with their personal training bridal package. I lost about 4% body fat, looking leaner than ever, and as a bonus got stronger and fitter overall! The personalized attention and care given to their clients coupled with their extensive knowledge and expertise is what makes them the best around! It is now after the big day and I'm enjoying continuing my training in their group classes and satellite program. Can't recommend enough :)
