Fred and the team at Mach983 CrossFit - Aurora, CO are some of the best coaches I've ever seen. They don’t just lead workouts - they pay close attention to every detail, from spotting when your form starts to slip to adjusting the weight so you’re challenged but not overwhelmed.Whether you’re trying to get in shape for the new year or get swimsuit ready for the summer, they create workouts that push you just the right amount. The energy in the gym is motivating without being intimidating, and you can tell everyone genuinely wants to see you improve. Mach983 is the best gym in Aurora because it combines expert coaching with a welcoming atmosphere where progress feels real and achievable.

Very friendly community, great environment and great vibes! The coaches are professional and very patient. I am new to CrossFit and was worried about getting myself hurt at the beginning, but with their detail instructions I can focus on getting better and stronger each session!

Coach Trevor was a great help in getting my started on my CrossFit journey! I definitely want more, and I'm coming back. I got my work cutout for me, but the positive reinforcement was gold.

Gem of a box! Dropping in around Christmas is hit or miss on available classes, but Mach983 has Christmas eve classes and open gym on Xmas day (believe me when I say I NEED that)! Well run class and friendly folks. Good time all around!

Ryan's classes are always a good challenge, especially at 5am! He is a wonderful coach and always good for some extra 1-1 tips or conversation if needed.

This was probably one of the best gym experiences I’ve ever had. Trevor is awesome! He helped me with proper form and technique and kept me encouraged and motivated through the entire session. He took the time to explain each workout and genuinely cared about each person’s individual abilities, never pushing anyone past their comfort level.The workouts absolutely kicked my ass — in the best possible way! I left excited, optimistic, smiling, even while walking home on limp noodles. The other guests were kind and welcoming, and I honestly can’t wait to book my next workout. Thank you!
