100% resistance-based HIIT. High-tech stations. Coach-led. Max 12 per class.
The Method
Why This Workout
Is So Remarkably Effective
Resistance-Based HIIT
100% resistance-based — no running, burpees, treadmills, no sharing equipment. While 99% of traditional HIIT mixes cardio and bodyweight, every exercise at Flex 'n Burn is 100% resistance-driven exercise for maximum muscle stimulus and calorie burn.
High-Tech Workout Stations
Each client gets their own high-tech station exclusively for the full 30 minutes. Push-button resistance adjusts instantly from 1–100 lbs per handle. Cables slide up and down and can face any direction — enabling every single exercise possible, from one station. This lets your Coach customize the perfect challenge for your strength and fitness level.
Secret Proprietary Training Methods
The workout blends advanced training techniques the average person would never discover on their own — applied so naturally that clients feel the effectiveness before they even realize what's happening. After just one class, it's easy to see and feel you'll get results!
Expert Semi-Private Coaching
A maximum of just 12 clients per class guarantees your coach can help instruct and guide every person individually — and as a group. You're never left guessing, never invisible, and never stuck with bad form.
High-Tech Stations
One Station.
Every Exercise. 30 Minutes.

Our Workouts
Three Ways to Burn
Each class targets different muscle groups through our proprietary resistance-based HIIT system. Pick your burn — or do them all.
Lower Body Burn
Target your glutes, quads, and hamstrings with resistance-based stations designed to sculpt and strengthen your lower half. Every rep is coach-guided for maximum results.
Muscles Targeted
Upper Body Burn
Build defined shoulders, arms, chest, and back with push-button resistance stations. Semi-private coaching ensures proper form and progressive overload every session.
Muscles Targeted
Total Body Burn
The ultimate full-body session — hit every major muscle group in one 30-minute class. Combines upper and lower body exercises for a complete head-to-toe burn.

Track Your Progress
Earn the Burn.
Track Your Stats.
Every rep counted. Every joule earned gets you closer to your goal. At the end of each class, your Flex station shows your personal stats. Simply — screenshot it, upload it to the FNB Stats App and watch your progress build over time!
Step 01
Screenshot Your Station
At the end of every class, your Flex station screen displays your total Reps and Joules. Take a quick screenshot with your phone before leaving at the end of class.
Step 02
Upload to FNB Stats App
Open the FNB Stats App, upload your screenshot and the app automatically analyzes, extracts and records your Reps, Joules, class type, time and date.
Step 03
Watch Your Progress
Track your personal bests, compare class types, and see your Reps and Joules climb over time. Progress you can actually see — class by class, week by week.
Your total cumulative energy — how hard you pushed or pulled, your resistance level, range of motion, and total reps all combined into one intensity score.
Goal: Keep pushing your Joules higher as exercises get easier. More effort + more resistance = more Joules = more results.
Your total repetitions across the full 30-minute class — a direct measure of your workout pace and consistency throughout every interval.
Goal: Aim for 15+ reps per set to spark the right metabolic response. 20+ reps ignites even more afterburn.
FNB Stats App
Track Every Class.
Own Your Progress.
The Flex 'n Burn Stats App automatically pulls your Reps and Joules from your station screenshot — no manual entry. See your personal bests, compare Upper, Lower and Total Body workouts, and track your journey class by class.
