02 / The coach who lived it
The before photo
was the coach.
Corey Willis owned four gyms, wrestled in college, and went 8–0 as an amateur fighter. Then life as a business owner caught up with him. Training for his first pro fight in 2021, he saw his own footage — and built the program that took the weight off and kept it off.
That program became Knockout Lifestyle. Every challenge in this gym runs on the same system he used.
- Amateur MMA record
- 8–0
- Gyms opened by 2017
- Four
- Turned pro
- 2021
- Kept it off
- 2+ Years
03 / The proof
Proof beats
promises.
Twenty-three members let us publish their before-and-afters — different starting points, same four rounds a week. Swipe through, then see the full wall.
The manifesto
It's not a quick fix. It's four rounds a week — movement, food, habits, and a coach in your corner — until the mirror agrees.

Trainers and classes are amazing at Knockout! Everything is planned out for you and the trainers will modify anything for you if needed. They all want you to succeed, especially Corey Willis. My gym family truly feels like an extended family!

I have joined the boomer class that Nancy has put together. It is amazing and is booming. 😁

Knockout isn't just a gym it's a family. One that lifts you up and challenges you to be better! I have seen many transformations being there for a few years but watching people holding the results from those transformations is what sets Knockout aside from the rest. Support, knowledge and fun!!!

The staff/trainers are all excellent and help keep me motivated. I appreciate the positive encouragement they all share!!!
Tiffany M.
Absolutely love this gym!! The trainers have been amazing!! They make working out fun and have multiple times that work with multiple schedules. Have worked out with Chris Brown for over a year and she has helped me hit an almost 100 pound weight loss. Definitely worth it!!

I got a personal trainer after getting in a car wreck and having some limitations in what I could and couldn't do. Adrienne has been a complete and total godsend. My neck and back aren't killing me anymore thanks to the muscle building. The whole gym is fabulous in itself and not as intimidating as some of the bigger ones!

Chris Brown is an awesome trainer, and she has gotten me into excellent shape! I highly recommend.

Corey and the crew at Knockout Lifestyle are so supportive! I started overweight with no experience lifting and I'm already seeing great results. The energy in the gym is welcoming, but you also have your own space and feel safe. Check them out if you're looking for something different!
