Making weight
without wrecking it

The two hour weigh-in changes the whole problem

Powerlifting and weightlifting weigh in roughly two hours before you lift, which is one of several things nobody tells you before your first meet. Professional boxing and most of MMA weigh in the day before, often 24 to 36 hours out.

Amateur boxing is not in that second group, and this is the correction that matters. England Boxing weighs in on the day: the rule book puts a domestic weigh-in one hour before boxing starts, and a championship at three hours recommended for the first round and one hour required thereafter. An England Boxing amateur is in the two hour situation described above, not the 24 hour one, and there is no night of rehydration to plan around. Our boxing weight class tool works to the same rule.

That difference is why advice copied from a professional will hurt both a lifter and an amateur boxer. A fighter who drops five percent of bodyweight the day before has a full day and night to put it back, with a doctor at the venue and a coach who has done it fifty times. You have two hours, a cafe queue and a warm-up to get through.

Everything below assumes the two hour version unless it says otherwise.

Two completely different jobs, and people conflate them

The chronic cut is losing actual body mass over months. It is a training and nutrition problem, it costs you some strength, and it is the one that should be doing almost all of the work.

The acute cut is the last few days: water, gut contents and glycogen. It is temporary, it comes back, and it is the one that wrecks meets when it is asked to do too much.

If you are relying on the acute cut for more than a couple of percent, you did not make weight. You gambled, and the bill arrives on the platform.

Pick the class months out, not weeks out

The real decision is made twelve to sixteen weeks before the meet, and it is arithmetic. Take your honest average morning bodyweight over a fortnight, not the lightest number you have seen. Compare it to the class limit.

• Within about 2%. You are in the class. Nothing dramatic needed, hold your weight steady and manage the last few days.
• 2% to 5% over. A chronic cut, run slowly, starting now. Detail below.
• More than 5% over. Either you have a long run in and a genuine reason, or you lift in the class above. Being the smallest lifter in a heavier class beats being a depleted one in a lighter class, and it beats it more often than anyone admits.

The chronic cut, in numbers

Aim for 0.5% of bodyweight per week, and treat 1% as the ceiling. For an 85kg lifter that is around 400g a week, which feels insultingly slow and is exactly why it works: it is slow enough that strength mostly survives it.

Three things make the difference between a cut that preserves the peak and one that does not.

• Protein stays high the whole way. Roughly 2g per kg of bodyweight per day. This is the single most protective variable when calories are down.
• Training volume comes down before intensity does. Keep lifting heavy, do less of it. Cutting the heavy work first is what makes people feel weak.
• Finish the chronic cut before the peak starts. Be at or very near class weight two to three weeks out, then eat at maintenance through the taper. Trying to lose weight and peak in the same fortnight is the classic way to arrive flat.

The last week, and what actually comes off

Three things come off, in this order of how cheap they are.

• Gut contents. One to two days of low fibre, low residue eating empties out what is sitting in your digestive tract. Often worth 0.5 to 1kg and it costs you almost nothing in performance. This is the free money and most people never take it.
• Glycogen and the water bound to it. Every gram of stored carbohydrate holds roughly three grams of water. Dropping carbohydrate for a day or two sheds real weight, but it also sheds the fuel you were going to lift on. Use this sparingly and put it straight back after the weigh-in.
• Body water. The expensive one. Dehydration reduces strength, power and concentration, and with a two hour weigh-in you cannot fully undo it. This is the lever to touch last and least.

Water loading, honestly

You will read about drinking large volumes for several days and then cutting fluid sharply. It is real, it is common in combat sport, and I am not going to pretend it does not work.

I am also not going to write you a protocol for it, and that is a coaching judgement rather than squeamishness. It has a genuine risk of hyponatraemia if it is done badly, the dose that works is individual, and the payoff for a lifter with a two hour weigh-in is small because you cannot rehydrate into the platform anyway. The risk sits at the wrong end of the trade. If you are going to do it, it needs someone experienced watching you in person, and the first time is never on meet day.

Rehearse it, once, in training

This is the most useful thing on this page. Run your last three days as a full dress rehearsal four to six weeks out, on a normal training week, ending with a heavy session at the time your meet starts.

You find out what you actually weigh after those three days, whether the food you planned sits well, and whether you can still lift on it. Finding any of that out for the first time on meet morning is how people end up stripping in a toilet cubicle at 8am.

The two hours after the scale

The goal is fuelled and comfortable, not full. A stomach working hard on a big meal is not helping you squat.

• Fluid with electrolytes, sipped. Not a litre in one go. Something with sodium in it, taken steadily across the whole two hours, absorbs better and stays down.
• Carbohydrate you already know you tolerate. Roughly 1 to 1.5g per kg of bodyweight, low fibre, low fat. Rice, white bread, sports drink, sweets, whatever you have eaten before a heavy session a hundred times. Meet day is not the day for a food you have never had.
• Stop eating properly before you warm up. Sip from there.
• Aim to be urinating normally and pale before you lift. If you are not, you are still down on fluid and you should be honest with yourself about your attempt selection.

When to abandon the cut

Not a badge of honour to push through any of these. Eat, drink, lift in the class above, and enter another meet.

• Dizziness, cramping, a pounding heart at rest, or a headache that will not shift
• Not urinating for many hours, or urine that stays very dark after drinking
• Confusion, or feeling detached from what is going on around you
• Being more than about 2% out with under 24 hours to go and no plan that does not involve a sauna
• Any point where the cut has started to feel like a reason to eat less in general

That last one is the important one. Weight classes give a sport a socially acceptable vocabulary for restriction, and a meet is not worth a relationship with food. If any of this is starting to feel familiar in a way you do not like, talk to a GP rather than a coach, and that includes me.

The short version

Choose the class in the off season. Do the losing slowly and finish it before the taper. Take the free kilo out of your gut in the last two days. Leave water nearly alone, because with two hours you cannot buy it back. Rehearse the whole thing once before it counts.

And if the arithmetic says you are five percent over with six weeks left, the answer is the class above. The strongest version of you at 93kg will out-total the emptied out version of you at 88kg nearly every time.
