Boxing burns between 500 and 800 calories per hour depending on your body weight, intensity, and the combinations you're throwing. Not all combinations are equally demanding. Our coaches at Onyx have identified five combinations that consistently produce the highest caloric output while building real boxing skill.
A Quick Note on Combination Numbering
If you're new to boxing: 1 = jab, 2 = cross, 3 = left hook, 4 = right hook, 5 = left uppercut, 6 = right uppercut. Southpaws are reversed. Your coach at Onyx walks you through every number in class.
Combination 1: 1-2-3-2
Why it burns
Jab, cross, hook, cross — four punches, two power shots, continuous hip rotation. The rotation from cross to hook and back to cross generates significant torso engagement throughout. When thrown at speed for full 3-minute rounds, this combination is a full-body cardiovascular and strength workout. Coach Val's personal favorite — smooth, fast, and finishing strong.
Combination 2: 1-2-5-2
Why it burns
Adding the uppercut (5) between the cross and final cross forces a dramatic shift in body mechanics — you drop level slightly for the uppercut and come back up for the power cross. This level change adds a squatting motion, engaging your legs and glutes in a way straight-line combinations don't. Level changes are significantly more metabolically demanding.
Combination 3: 1-2-3-2-3-2
Why it burns
A six-punch combination — exactly as demanding as it sounds. The extended sequence forces you to maintain form under fatigue. Core stays engaged through all six punches, feet keep moving, breathing must be controlled throughout. Coach Tanner's go-to for conditioning rounds. Done properly at pace, a single round of this tells you exactly where your fitness stands.
Combination 4: 5-6-3-4
Why it burns
Starting with back-to-back uppercuts (5, 6) before transitioning to left and right hooks creates a full rotational sequence from the core. Uppercuts generate power from the legs through the hips and shoulders — they're arguably the most full-body punches in boxing. Coach Sporti uses this specifically for its full-body demand.
Combination 5: 1-2 slip 3-2
Why it burns
The slip — a lateral head movement — between the initial 1-2 and follow-up 3-2 adds a defensive movement to the offensive sequence. Throwing, moving, throwing again creates a boxing-specific interval effect: short bursts of intense output followed by explosive movement followed by more output. This pattern is extremely effective for fat burning and is the foundation of how boxers train for fight conditioning.
How to Use These
These combinations are most effective drilled in rounds — 2 to 3 minutes on, 30 to 60 seconds off. Three to four rounds of a single combination at sustained pace is a complete fat-burning workout. The most important variable is not which combination you're throwing — it's the pace you maintain and the quality of your movement throughout.
