Round one, thirty seconds in. Your right hand is at your hip, your chin is pointing at the other guy like it wants to introduce itself, and you have not breathed since the bell. I know, because I was that person, and because every coach in every gym in every country watches the same seven things happen to every beginner. They are not a sign that you are bad at this. They are what an untrained body does when you ask it to hit something, and each one has a known cause, a known cost and a drill that fixes it in a few weeks.

The short version: stance and guard first, because every other mistake grows out of those two. Then breathing, then the punches themselves, then the eyes. Here they are, in the order they will ruin your evening.

The seven mistakes

1
Standing square or with the feet crossed
2
Hands low, chin up
3
Holding your breath and tensing everything
4
Loading up on every punch
5
Not bringing the hand back
6
Leaning in and reaching
7
Closing your eyes and turning away

1. You are standing like you are waiting for a bus

What the coach sees: Feet on one line, weight on the heels, or the back foot sneaking behind the front one when you move sideways. You are either a plank that any push topples or a tangle that trips over itself.

Why your body does it: Standing square feels strong, because it is how you stand for everything else in life. Nobody ever needed a boxing stance before the first day.

What it costs: Balance, power and defence, all at once. A square stance has no back leg to drive the cross, no angle to tuck the chin behind the lead shoulder, and nothing to stop a jab from rocking you onto your heels. Crossed feet are worse: one clean shove and you are studying the ceiling.

The fix: Front foot pointing at the target, back foot a shoulder's width behind and half a step to the side, back heel light, weight in the middle. Move by stepping with the foot nearest the direction you are going and dragging the other after it. The feet never cross, the stance never closes, and you can stop reading the ceiling.

The drill: Tape a line on the floor. Three rounds of shadow boxing with the front foot on one side of it and the back foot on the other, moving in all four directions. If a foot crosses the line, freeze and reset. A week of this and it is gone.

2. Hands low, chin high, invitation open

What the coach sees: The guard sinks to chest height between punches, the elbows drift out like wings, and the chin lifts as if it is trying to see over a fence.

Why your body does it: Holding the hands up hurts. The shoulders burn after two minutes and nothing in ordinary life ever asked you to protect your face. Then adrenaline arrives in sparring and makes it worse: the head comes up to see, the hands come down to hit.

What it costs: Everything. A low guard and a raised chin are the two ingredients of a knockout, and you are supplying both. Every counter lands, and you will not see it, because a chin that points up takes the eyes off the other person's hands.

The fix: Knuckles on the cheekbones, palms towards you, elbows in against the ribs, chin tucked so that you look out from under your eyebrows like you are suspicious of the whole room. Shrug the lead shoulder a little to hide the chin behind it. The shoulders will burn for a month. That is the fee.

The drill: Three rounds of shadow boxing in a mirror, watching only the hand that is not punching. Every time it leaves the cheekbone, say "hand" out loud and put it back. Then bag rounds with a partner calling "hands" every time they drop. It is boring. It works.

3. Holding your breath like you are under water

What the coach sees: A red face, a clenched jaw, shoulders up round the ears, and total exhaustion after a single round of bag work that should have cost nothing.

Why your body does it: Effort. The body's answer to trying hard is to brace and hold the breath, which is perfect for lifting a fridge and useless for throwing two hundred punches.

What it costs: Stamina and speed. A tense arm is a slow arm, and a three-punch combination on one held breath leaves you gasping before the round is half done. Most beginners who think they are unfit are simply clenched.

The fix: A sharp exhale on every punch – the "tss" you hear from people who know what they are doing – and an inhale between combinations. Between punches the arms hang loose; the fist tightens only at the moment it lands. Think whip, not crowbar.

The drill: Bag rounds at half power where the only goal is to hear your own exhale on every punch and to feel the shoulders drop between combinations. When the breathing runs itself, put the power back.

4. Every punch is the last punch of your life

What the coach sees: Haymakers. The shoulder pulls back before it goes forward, the whole body winds up like a discus thrower, and you are announcing the punch a full second before it leaves.

Why your body does it: Power feels like effort, and you want every punch to matter. Films do not help.

What it costs: Speed, surprise and your own face. A wound-up punch is slow, visible, and leaves the guard open for the whole wind-up, and it lands softer than a short one, because power comes from the hip and the timing, not from the backswing. It also empties the tank: ten loaded punches cost more than fifty crisp ones.

The fix: Punch from where the hand already is. No backswing, none. The power comes from turning the hip and the foot on the punching side and from the snap at the end. Aim to touch the target fast and let the hips decide how hard.

The drill: Jabs and crosses on the bag with the back of the punching hand starting in contact with your cheek. If it moves backwards before it moves forwards, the rep does not count. Three rounds, then the same in shadow boxing with someone watching your shoulder.

5. The hand that went out and never came home

What the coach sees: The punch lands and the arm stays there, or drifts down and back to the hip. For half a second there is a straight arm in the air and a face with nothing in front of it.

Why your body does it: You think the punch ends at the target. It ends at the guard.

What it costs: The counter. Every experienced opponent throws over or under a hand that stays out, and the jab left hanging is the classic set-up for the right hand that ends the round. You are not throwing a punch; you are opening a door.

The fix: Out and back is one movement, and the return is faster than the delivery. The hand comes straight back along the same line to the cheekbone, not down and round the houses.

The drill: Double jabs and jab-cross on the bag while a partner holds a pad next to your head. If the punching hand is not back on guard before the next punch, they tap you with the pad. Ten taps in the first round is normal. Two by the third is a boxer.

6. Leaning in like you are reading small print

What the coach sees: You cannot reach the target from where you stand, so instead of stepping you lean, head first, until your nose is past your front knee.

Why your body does it: Stepping is slow when you are new, leaning is instant, and the bag never punishes it.

What it costs: Balance and the chin. A leaning head is a chin hand-delivered to the other person, and a body past its front knee cannot move in any direction. Reaching also guts the punch, because the hips are behind the arm instead of underneath it.

The fix: The head stays behind the front knee. Always. If the target is too far, step with the front foot as the punch starts and let the back foot follow; if it is too close, step back. Distance is a job for the feet, never for the spine.

The drill: Shadow box with your toes a fist's length from a wall. Your head must not touch the wall on any punch. Then bag work with a coach watching the line of your nose over your front knee.

7. Eyes shut, head turned, hoping for the best

What the coach sees: A punch comes, the eyes close, the head turns away, and you duck blind into whatever arrives next.

Why your body does it: It is the oldest reflex you own and it has protected you all your life. Boxing is the first thing that asks you to override it.

What it costs: You cannot defend what you cannot see. Turning away offers the side of the head and the back of the ear, both worse places to be hit than the guard, and a blind duck walks straight into the uppercut.

The fix: Eyes on the other person's chest, where you see both hands and the shoulders that announce them, and a guard you trust enough to let punches land on it. The reflex fades only with exposure. Willpower has nothing to do with it.

The drill: A partner throws slow, announced punches at your guard while you keep your eyes open on their chest and answer with a jab. Speed goes up over weeks, never within a session. The day you take a punch on the gloves without blinking is the day you started boxing.

Where to go next

Frequently asked questions

How long does it take to fix bad boxing habits?
Two to four weeks per habit if you drill it every session and someone tells you when it slips; much longer if you only notice it in sparring. Habits are not deleted, they are replaced – you need a new pattern to fall into under pressure, which is why every fix here comes with a drill.
Why do I drop my hands when I punch?
Because the punching hand goes back to where it started, and beginners start it low; and because fatigue and adrenaline pull everything towards the floor. Fix the start position first – knuckles on the cheekbones – and the return follows. Shadow box in front of a mirror and watch only the hand that is not punching.
Is it normal to feel exhausted after one round on the bag?
Yes, for the first month, and most of it is not fitness. You are clenching every muscle and holding your breath. The day you exhale on every punch and let the arms hang loose between them, the same round costs half as much.
Should I learn defence or offence first?
Stance and guard before any punch. A punch thrown from a bad stance with the other hand down teaches two mistakes for every technique. Coaches who spend the first weeks on stance, guard and the jab are not being slow. They are saving you a year.
How do I stop flinching and closing my eyes?
Slowly and by exposure. A partner throws slow, announced punches at your guard while you keep your eyes on their chest, and the speed rises over weeks. Flinching is a reflex you cannot switch off by wanting to; the nervous system needs a few hundred safe repetitions before it believes you.
Do these mistakes apply to kickboxing and MMA too?
All seven. The stance is squarer in kickboxing and MMA and the hands sit a little differently to cover kicks and takedowns, but dropped hands, crossed feet, held breath, loaded punches and a chin in the air cost exactly the same wherever you are hit.
