CrossFit® 643: Reviews

5/5 (5 Reviews)

Fantastic experience: I can’t say enough about 643. The atmosphere is and always has been one of encouragement, support, motivation, and fun. My skill level improved by leaps and bounds in my first 6 months with Michele. 5 years later and I’m still learning new skills and improving my strength, all alongside a supportive community and under superb coaching. Even those with no prior CrossFit experience (or no athletic experience at all) achieve goals never thought possible and find the drive to push harder and do more. 643 welcomes all and our current members are a LOYAL and caring family. We want to see you succeed. Give it a try and expect to love it.

Fantastic experience: I have been at 643 since 2016 and I truly can say everyone here is like family! CrossFit it a great way to stay in shape and doing it in small to medium size groups with a coach was the best choice for me! Not only do you push yourself to your highest limits, but you learn movements that you never thought you could do before and make amazing friends and relationships along the way! Michele, the owner, is experienced with new beginners to the most elite athletes. And does so many fun activities to keep the community engaged. I Definitely recommend coming by to check her and her gym out!

Fantastic experience: Look no further to fit your fitness needs! This upbeat, friendly gym changes the fitness game. When you walk in, you are treated like family. This community is one of the best groups of people I have ever met. They are there to support you, motivate you and get you to meet your goals. They even help you reach goals you never once thought were possible! Can't say enough positive things about this gym!

Fantastic experience: I started at 643 over 4 years ago and it have been a God sent. The coaches worked with me to make me feel comfortable and welcomed. I am very fortunate to have been introduced to CrossFit at my age, but age is only a number and at 643 they do not care about age. They care about me physical and mental ability to reach my goals. There is NEVER any pressure to be like other athletes. 643 is my family not just a gym!

Fantastic experience: The BEST place for EVERYONE to workout!!! From the serious competitive athlete to the individual just looking to get a little fitter for health, CrossFit 643 is for you. The community is unparalleled, each member cheers on the others, encouraging them to do their very best, whatever that is. Programming is scalable, which means there are always options for those who aren’t yet able to do an exercise or who have limitations. Because the workouts vary, it’s always exciting to participate in class. I love CrossFit 643 and I think you will too.
