Momentum Fitness Classes- CrossFit®, HIIT, Weight training: Opinions
Fantastic experience: CrossFit Momentum is a continuously great challenging experience. The coaches are knowledgeable, exemplary, and patient. Everyone has been welcoming and supportive. I went in with no prior knowledge or skill of the workouts. I’ve learned a tremendous amount of different workouts and each class is a non-repetitive learning session.
Fantastic experience: I moved to Nyack three years ago for graduate school and the first thing I looked for was a new crossfit gym, and boy did I find one! Crossfit Momentum has been a family away from home pushing me in strength and endurance at the gym. Each class time is filled with wonderful people who are always cheering you on to be your best, with the best coaches around. Safety is an important aspect for all the coaches along with pushing you to become the best athlete you can be! I highly recommend Crossfit Momentum if you are looking to meet wonderful friends and become a part of a great fitness family.
Fantastic experience: Crossfit Momentum is the best part of my day, everyday. I am stronger, fitter and happier since joining in January. The coaches and the members are welcoming, fun and helpful. The gym is so well run, and reliable in all aspects. The community and the support are second to none. I am so glad I joined and am so grateful for the experience!
Fantastic experience: I was a little nervous joining CrossFit Momentum a year ago-and at times wondered if I was cut out for CrossFit. Guess what- Everyone can do CrossFit! The coaches are fantastic -they teach and preach proper form and respect your limitations.They also easily modify the workouts to meet your needs and abilities. The members are welcoming and supportive. You really do become part of a team. The most important lesson I have learned while doing CrossFit is you can physically and mentally achieve much more than you thought possible! Hope to see you in class one day soon!
Fantastic experience: CrossFit Momentum continues to be a positive and supportive gym and community space for myself and many others! Whatever your goals are, you can enjoy high energy workouts, open gym time, lifting classes and yoga and progress at any age or fitness level. Skilled, friendly, and knowledgeable coaches paired with a tremendous sense of camaraderie among members makes this gym a wonderful place for fitness!!!
