"I began training with Mike Whetstone and his family / staff when I was in High School. The amount of knowledge that I have learned from this great group of people is astounding. 5 years later I am still using the skills they have taught me. Not only did I expand my physical strengths and limitations, my entire fitness mentality and nutritional mindset changed. This gym offers an absolute great experience for those who are both new and prestigious when it comes to physical fitness. No matter who you are or what you can do, you will learn the very best information from the very best coaches. The classes are fun, enjoyable, and can have amazing results. The high tempo vibes are constantly given off from the coaches, and they are always there next to you ensuring you're doing everything correctly and efficiently. They will push you to your limits, while maintaining a safe workout environment. Mike and all of CrossFit Nucleus helped me prepare myself and my body before joining the United States Marine Corps, and I can not be thankful enough. They gave me the physical and mental tools I needed to help better myself on a daily basis, and I look to all of them as family. Whether my form is off, or I have a personal problem at home, these people play a big role in my life. I challenge you to give this gym a try, it can change your life!"

"Great staff! Beautiful facility! The yoga instructor, Meredith, was very thorough with her directions and helpful in correcting the poses. The sauna was perfect and, the locker rooms were immaculate. They even have a child care area!"

"The trainers are all excellent and very knowledgeable. They make sure you’re movements are correct and watch closely at form. Anyone who is new to crossfit will have no problem transitioning into the sport with the trainers help! The people who attend were very welcoming. The equipment is clean and well kept. Overall, I’d highly recommend Crossfit Nucleus! It is where I started crossfit as a complete beginner, and through Crossfit Nucleus I have become stronger both mentally and physically!"

"I have been a member since May 2014 and it has been an amazing journey! The coaches are incredible and know how to help both those new to crossfit and seasoned veterans. Classes are fun, but challenging and everyone encourages and motivates one another. You'll push your mind and body to new limits that you didnt know were possible! Drop in for a visit and I know you won't be disappointed."
