Why Flex 'n Burn
Transform Your Body
& Your Life in
Just 30 MinutesTransform Your Body &
Your Life in Just 30 Minutes
The Flex 'n Burn Method is a 100% resistance-based HIIT workout that torches fat,
builds real strength and develops lean, toned muscle.
One method. Three results. Thirty minutes. That's the Flex 'n Burn difference.
Calorie Torch
Incinerate Fat —
During & After Class
The nonstop cardio-paced regimen keeps your heart rate elevated the full 30 minutes — torching fat while you train and triggering a 24–48 hour metabolic afterburn that keeps working long after you leave.
Strength & Tone
Sculpt Lean Muscle —
Rep by Rep
Resistance-based HIIT means every exercise trains and targets a specific muscle. High-tech push-button stations from 1–100 lbs and semi-private training help you progressively build real strength, increase lean muscle and definition — without a single burpee.
Metabolic Ignition
Rev Your Engine —
All Day, Every Day
The workout stimulates 5 body systems at once — firing up a faster, more efficient metabolism. Most members feel increased and sustained energy all day within their first week. Feel the difference before you even see it.
