“At the beginning of this year, I made a commitment to become the healthiest, fittest version of myself. Wholeheartedly investing myself in every aspect, be it fitness, nutrition, or mental well-being, giving it my absolute dedication and unwavering commitment. Little did I know that as my 34th Birthday approaches, I would be in the best shape of my life! After having Addie (Amber & Zach’s daughter), I settled into a state of contentment, forgetting all about the athlete hiding inside me. However, thanks to the incredible team at @f45_training_hudson , I have rediscovered my true identity, and embracing a healthy lifestyle that brings me immeasurable joy. The coaches have been an invaluable source of support, constantly pushing me to exceed my limits week after week. Whether it’s adding weights to my routine or leading by example during intense cardio sessions (shoutout to @sashabcpt), their dedication has been truly remarkable. I can 100% say that I am obsessed. I cannot express enough gratitude towards Zach Robins (Amber’s husband, another member in Hudson) , who has been unwavering in his support. Together, we are embarking on this journey, not just walking, but sprinting down this path towards a healthier and happier life.”

“This moment marks 300 workouts and an incredible 2.5-year weight loss journey, reflecting the power of perseverance and hard work. Through unwavering dedication, a high-protein diet, and consistent exercise, I’ve witnessed a remarkable transformation that continues to inspire me. Seeing the progress from my “Before” picture to my “After” photo serves as strong motivation to keep pushing forward. Each step of this journey has been a testament to the possibility of growth and change when we commit to bettering ourselves. I am deeply grateful for the unwavering support of my loving wife, whose encouragement has been a driving force behind my success. Additionally, my coaches have played an essential role in guiding me through the toughest moments and pushing me to reach new heights.”
“I came to F45 in the middle of my weight loss journey. I had already lost about 80 lbs. through dieting, but I knew I needed more exercise. I had done lots of cardio in my past, but I could never motivate myself to lift weights on my own. I immediately fell in love with F45. It was tough, but the trainers were so supportive and encouraging. They made sure my form was excellent, and they helped me modify as needed. I kept coming at least 5 days a week. The music was motivating, the routines were fun, and I met so many amazing people. The environment is really what sets F45 Hudson apart from the rest. There is such a culture of camaraderie. Everyone cheers each other on. I would get high fives and acknowledgment of a job well done from not only the coaches, but fellow members. You get the sense that everyone is rooting for your success. Linda has created such a positive and wonderful place to transform and better ourselves. I could sense it the minute I met with her to sign up. I am so incredibly grateful to her and all of the F45 Hudson staff. I went on to lose more weight, and am down just about 130 lbs. I have gone from a size 22 to a size 2. I’ve gotten stronger and can lift far heavier weights than I ever could before. But most of all, the over 100 workouts I’ve done at F45 Hudson have given me confidence and a sense of well-being that is priceless. My inner athlete, which hadn’t seen the light of day since my early 20s, has been reignited. I feel strong, fit, and capable. None of this would have been achievable without the support, guidance, and community at F45 Hudson. If you are in the fence about joining, DO IT!!! You are worth it!! And be prepared to have a team training, life changing experience.”


“F45 Hudson feels like a sense of community. All of the trainers motivate you to push yourself. And they really help modify things when necessary. Sasha is a beast and she is so sweet and always wants to see you do your best. Kevin always motivates you to go harder and is great with correcting your form and teaching you about different muscles and how each movement works them. Nik brings a great energy in the room and knows how to make every class fun! I don’t live in Hudson and I still drive 20 minutes to go to this location just because I love the staff so much. I would recommend F45 to everyone and it is definitely life changing and has built my confidence so much!”

“This is a safe haven to have an impactful, effective and thorough work out. The coaches are incredibly knowledgeable and caring for each person in their care. Feel intimidated and like you can’t do it? Don’t fret! They can modify for your needs and keep you moving safely and effectively. Heart and soul in every detail. Clean and sanitary to a fault. Everyone comes in with their personal journey and goal. They are there to help you reach yours. Transformational. No matter what you are looking for, you will not be the same person once you get a taste of what you can do!”

“Best place to workout, bar none. I may not be the fittest athlete out there, but the trainers celebrate my hard work as if I was a world class champion. Highly motivating environment, clean, fun, and as tough as you want to make it. All of the trainers are amazing!”

“Well run, clean, professional, and an all around fun place to be. I always look forward to that part of my day when coach says ‘line up on the turf!'”

“I joined F45 in January and have been hooked ever since! I genuinely look forward to going to classes in the morning and feel so supported by the coaches and members!! The facilities are spotless and always clean!!”

“Best choice I’ve made for a change up in my exercise routine. Took a class and was hooked instantly. Thought I’d use the classes as filler workouts a couple times a week, but I go 4 – 5 days a week. In and out in 45 minutes. I’ve noticed a difference right away. Best part is I’m only competing with myself. No one judges! And the coaches are great for even a little more push! Love it!”
