BURNFat & Calories

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.

BUILDMuscle & Strength

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.

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.
