Think CrossFit, without complexity.
CrossFit make you nervous? In Burn, we remove the complicated movements leaving just the stuff that WORKS.
Strong, Fast, Fit.
Burn offers all of the benefits of CrossFit. We build strength through simple and effective weightlifting, speed through bodyweight plyometrics and gymnastics, and all-around fitness through high intensity intervals.
Everything you need, nothing you don't.
Our 30-minute timeline is perfect for those pressed for time. If you want to get a quick, hard-hitting workout without spending all day in the gym, CFK Burn is just that.
Constantly varied, always FUN.
The workout is always different, always challenging, and most importantly, always a blast!
