How Many Calories Does Kickboxing Burn?

Kickboxing calories by weight & duration

The roughly 492 calories per hour figure is an estimate for a 155 lb person and your actual burn will shift based on your weight, fitness level, and how intensely you move through each round. You can log your kickboxing sessions and track how your numbers accumulate over time in the Mariposas app.

Calculated as MET (7) × body weight (kg) × hours. How this works.

What to expect in a kickboxing class

A first session usually opens with a dynamic warm-up that covers hip circles, shoulder rolls, and light footwork to prep the joints you'll be loading heavily. From there, the instructor breaks down two or three basic strikes, typically a jab, a cross, and a front kick, and drills them in short combinations before building them into longer sequences. Rounds often run one to three minutes with brief rest periods between them, so the pace feels interrupted rather than relentless, which actually makes it accessible. By the end of class your forearms, shoulders, and hip flexors will let you know they were involved, especially if it's your first time throwing punches.

Tips for your first kickboxing class

• Start with your stance before worrying about combinations. A shoulder-width split stance with your non-dominant foot forward and knees slightly bent gives you a stable base to generate power and absorb the rotation on every strike.
• Don't death-grip your hands. Keeping your fists loosely closed until the moment of impact reduces forearm fatigue dramatically over a 45-to-60-minute class and is actually the technique most beginners skip because clenching feels more committed.
• Watch your guard drop. After throwing a punch, both hands return to cheekbone height. Instructors notice this constantly in beginners because fatigue makes the rear hand drift to the hip, and building the habit early makes your combinations cleaner as the sequences get longer.
• Throttle back on the kicks until your hip flexors adapt. Front kicks and roundhouses pull heavily on muscles that most people underuse day-to-day, and going full force in week one is a reliable way to end up sore enough to miss week two.

What affects how many calories kickboxing burns

The 492 calorie figure is calculated for a 155 lb person using a MET of 7, and someone heavier will burn more per hour while someone lighter will burn less, simply because moving more mass requires more energy. How hard you push within the class has a real effect too: a person who throws punches with full hip rotation and snaps kicks through their full range of motion will work significantly harder than someone who keeps everything small and controlled. Interval structure also matters, since classes that compress rest periods or layer in plyometric bursts like jump knees between combinations will push your heart rate higher than steady-state shadowboxing.

Three things move your number most: body weight (a heavier body burns more for the same activity, that's why the table runs from 125 to 225 lb), duration (calories scale with time), and intensity. A kickboxing you push hard burns more than an easy one, because effort is what the MET value of 7 represents, an average for this activity. Your fitness level and how much you rest between efforts shift it too, so treat these as a solid estimate rather than an exact count.

How we calculate kickboxing calories

Every number here uses the standard energy-expenditure formula: calories ≈ MET × body weight (kg) × time (hours). The MET value of 7 for kickboxing comes from the published Compendium of Physical Activities, the same reference researchers and fitness trackers use. We convert your weight to kilograms and multiply through, no fudge factors. See our methodology for the full formula and sources.
