30-Minute HIIT Classes That Change Everything
Hampton Hustle Fitness offers the most engaging HIIT classes in St. Louis. Our format takes everything science tells us about high-intensity interval training and packages it into a 30-minute experience that uses boxing as the primary workout tool.
Instead of running on a treadmill or doing repetitive burpees, you'll be throwing combinations on the heavy bag, sprinting on jump rope, slamming medicine balls, and driving through kettlebell circuits — all within a precisely designed interval structure that maximizes calorie burn and physical conditioning.
Located at 4924 Hampton Ave in South St. Louis, our HIIT classes run all day with a no-class-times format. Walk in, start the circuit, and get 30 minutes of the best training of your life under coach guidance.
The Four Pillars of Every HIIT Class
Kickboxing & Bag Work
The heart of every session — striking combinations on the heavy bags that develop power, speed, and coordination while driving your heart rate sky high.
Strength Training
Kettlebells, dumbbells, and resistance movements integrated into the circuit to build lean muscle alongside cardiovascular fitness.
Core Training
Every HIIT class incorporates targeted core work through boxing-specific movements, planks, and stability exercises.
Interval Cardio
Jump rope, agility drills, and plyometric movements that elevate heart rate and build the endurance to push harder every session.
HIIT Classes for All Fitness Levels
The beauty of HIIT training — when coached properly — is that it works for every body. Intensity is relative. For a beginner, working at 80% of their capacity IS high-intensity. For an athlete, the same circuit challenges them in different ways. Our coaches at Hampton Hustle understand this and coach each member accordingly.
We've seen complete beginners transform their fitness in weeks. We've seen former athletes rediscover their love of training. We've seen members in their 50s feel stronger than they did at 30. This is what happens when great coaching meets the right format — and HIIT boxing is that format.

All of our sessions are 30 minutes. This is intentional — 30 minutes of structured, coach-guided HIIT is more effective and efficient than longer, less focused workouts.
