Sigma is truly a great place to train crossfit. I'm glad I joined back in December 2013. I am crazy strong now because of the programing of this gym. This gym gives its members the feeling of a community. I am motivated by the atmosphere and the coaches to really push myself when I thought I didn't have anything left to give. There's a lot of different equipment and very varied workouts to take your fitness to a new level. The coaches there are absolutely awesome. Ted is very knowledgeable, motivational, and gives everyone personal attention.

This is by far the best CrossFit gym I have been to. As a CrossFit trainer myself, I know that sticking to proper form maximizes your fitness AND keeps your body safe. That's what I love about Sigma. They always emphasize proper form and technique. This gym is perfect for those just starting out or advanced athletes looking to push through plateaus. Highly recommend if you're in the area.

Sigma Crossfit has to be one of the most well rounded crossfit boxes out there. The coaches are knowledgeable and great at teaching the fundamentals of all the movements of crossfit. They teach you the correct safe techniques for every lift. They are approachable and always willing to work with you. The people that come to the gym are great as well. Everyone is there to get a good work out in. They are not afraid to cheer you on and motivate you to push yourself. The athletes there are at many different levels of being fit from elite to just starting. The equipment is clean and they gym is always getting new gear and equipment. I’ve been working out at sigma for over 2 years and I have no plans on leaving. The results are amazing which drives me to keep working. I have more confidence in the way I look now. I like to credit Sigma to the reason I was able to find a firefighting job. I was able to take the physical agility test and finish 1st or 2nd on every time. I look forward to coming to the gym everyday not just for the work out but for the great people that work out with me.

If you are interested in crossfit then this is the place to be. This is a safe environment to push your self with coaches who wont allow you to get hurt. All of the coaches are enthusiastic and strive to see their atheletes improve. It is truly a great place to be.

If you are considering a Crossfit in the local McKinney / Frisco area, Sigma Crossfit would be a sure bet. Ted is an amazing trainer to work with. He spends time instructing, and shares insights into why you should move each way. He and the other trainers are extremely supportive, and care about their clients.
