I want to share my enthusiastic recommendation for Spencer, an exceptional personal trainer who has been instrumental in transforming my fitness journey. From the moment I started training with him, I could sense his passion for helping people achieve their fitness goals. Spencer possesses a deep understanding of exercise science and nutrition, tailoring every workout to suit individual needs and abilities. His positive energy and encouraging demeanor create a supportive environment, making each session enjoyable and motivating.

What sets Spencer apart is his commitment to ensuring overall well-being. He doesn't just focus on physical strength but also emphasizes the importance of mental and emotional health. His holistic approach has significantly improved my confidence and overall outlook on life. Spencer is adept at pushing you beyond your limits while ensuring safety and proper form. His attention to detail and constant feedback have helped me progress faster than I ever thought possible.

Whether you're a beginner or an experienced fitness enthusiast, he will undoubtedly elevate your training and help you unlock your full potential. If you're ready to embark on a transformative fitness journey with a dedicated and compassionate trainer, Spencer is the perfect choice.

I had been doing strength training for more than 25 years when I started working with Spencer. I thought I knew what I was doing, but Spencer proved me wrong. My goal was to improve my powerlifting, but herniated discs from an old injury were causing setback after setback. Spencer brought a very disciplined approach to my training, beginning with mobility improvement, flexibility, a focus on core strength and many exercises I had never tried before. In less than two years, Spencer coached me to a 3-lift total of 1100 lbs, a 300 lb increase from where we started. Mind you, this was at the age of 50.

Spencer isn't your typical fitness trainer. He is not just some guy who earned an easy online cert and goes through the motions at a McGym. He has rigorously studied fitness, nutrition and human performance his entire adult life. It's his true calling. He stays on top of the science, brings a disciplined approach, and practices what he preaches. Give him 6 months, follow his guidance, put in the work, and you will be thrilled by the results. I've left Vermont, and training with Spencer is one of the things I miss most about the Green Mountain State.

I was turning 60 and wanted to get into shape. Both my parents were in their 90s, and if I lived to their age, I wanted to be physically able to care for myself. I knew that to achieve that goal, I needed help. I met with Spencer Cloutier, and since then, I have not looked back.

When I started working with Spencer three years ago, I experienced pain in my left knee. We work on strengthening my leg and stretching my hip. It took some time, but now, the pain is gone.

I highly recommend Spencer and Green Mountain Iron Fitness. Spencer’s professionalism, passion, and results orientation keep me returning week after week. Thank you, Spencer, for helping me become and stay strong.

As a woman going through perimenopause, I was noticing a gradual weight gain and the inability to slough if off as easily as I could in my 20s and 30s. In addition, I had a shoulder injury and chronic hip pain which increased my reluctance to lift weights for fear of reinjuring myself. This led to inconsistent workouts, slowly diminishing to none as time went on. I decided to seek out a personal trainer and began my training with Spencer Cloutier two years ago with the intent of staying consistent with workouts, toning, maintaining a healthy weight and not hurting myself.

What Spencer brings to personal training is not only his wealth of knowledge and tremendous experience on the subject of fitness and personal training, but his ability to focus on his client’s specific needs. He is not of a “one size fits all” mind set. He spent a considerable amount of time listening to my goals and learning about my lifestyle. Spencer designed a unique workout that has allowed me to tone whilst providing me with consistency to ensure I reach my goals. It has resulted in increased strength, decreased cravings and has done wonders for my confidence!

I started working with Spencer in an effort to jumpstart my way back to fitness after a major slump during the pandemic. My wedding is this year which definitely added some motivation. Spencer’s workouts have challenged me in a way that has been extremely empowering. I can truly say I feel stronger after each session. Spencer’s expertise and years of experience are evident and I am crushing my goals in a way that feels safe, supported and sustainable. I would highly recommend Green Mountain Iron Fitness to anyone looking to start or to expand a fitness routine!
