Train With
Intention.
Every Zone4 class is built on heart-rate training, kickboxing-based conditioning, and a different daily focus — so no session is wasted and every session has a purpose.
The 4th Heart Rate Zone:
Where Transformation Happens.
Heart-rate training gives every workout a purpose. Zone4 focuses on the 4th heart-rate zone — a higher-intensity training range designed to challenge your body, improve conditioning, support calorie burn, and build a stronger engine over time.
Heart-rate zones are training-intensity ranges and are approximate. Zone4 is a fitness program, not medical advice — results vary by individual.
Efficient. Effective.
Built for Results.
Training in the 4th zone helps you get more out of every class — a smarter way to work toward the results you're after.
