A 68 kg athlete adding 60 kg to a pull-up and a 95 kg athlete adding the same 60 kg have not done the same thing. Everything about running a streetlifting event follows from that one sentence. Before the first bar is loaded there is a set of scales, a time window and a sheet where every athlete writes down what they intend to attempt.

Why bodyweight changes everything

On a bodyweight movement the athlete is already moving their own mass. The added load sits on top of that baseline work. A heavier athlete shifts more total mass for the same number on the belt, while a lighter athlete produces a better ratio between what they lift and what they weigh. Comparing the two on the plate number alone means nothing, and athletes know it before they even register.

Two mechanisms answer that problem and they sit together well. Weight categories group comparable frames and produce a podium per band. The coefficient takes the total back to bodyweight and produces one overall leaderboard. Most events run both, with podiums per category and an overall title on the best coefficient.

How weight categories are actually split

There is no universal split. Every federation has its own and an independent event sets whatever it likes. The real criterion is not tradition, it is how full each band ends up. A category with three entries does not produce a credible podium, and a category with thirty stretches the heat and makes the day hard to hold together. Somewhere between eight and fifteen athletes per category, the format runs well.

Publish the limits when registrations open, not the week before. A 71 kg athlete needs to know straight away whether to cut down or to move up. If a category is still empty at the deadline, merge it into the neighbouring one and announce that the ranking there will be settled on the coefficient, rather than keeping a podium with two people on it.

The coefficient that brings the total back to bodyweight

An athlete's total is the sum of their best successful lifts across the movements. The coefficient multiplies that total by a factor derived from official bodyweight. The heavier the athlete, the smaller the factor. The result is a unitless score that compares across categories. The tables in use usually come from powerlifting, sometimes adapted to weighted bodyweight movements.

One rule belongs in your rulebook in plain words. Say whether the category ranking or the coefficient ranking decides the prizes. Both are defensible, but an athlete who finds out on the day that their podium does not count will not come back next year.

How the weigh-in runs

The weigh-in takes place inside an announced window, usually one to two hours before the category is due on the platform. One set of scales, in the same room for everyone, checked in the morning. The athlete shows ID, steps on, and the number recorded becomes their official bodyweight. That number sets the category and feeds the coefficient, whatever was declared at registration.

The weigh-in is also where each athlete declares an opener, the first load they will attempt on each movement. Those declarations are what let you order the running, lightest load first. Without them you cannot build the heat and you spend the day calling athletes back one at a time. Budget two minutes per athlete with two people on the station, one weighing and one entering.

Three attempts and a bar that only goes up

Each movement gives three attempts. The declared load never comes back down, it goes up or it stays the same after a miss. The minimum increment is often 2.5 kg. A judge passes or fails the attempt against the range of motion set in the rulebook, arms straight at the bottom, chin over the bar, elbows locked at the top of the dip.

After an attempt the athlete calls the next load within a short deadline, and a minute is enough. That deadline is not paperwork, it is what lets you load the bar while the next athlete is lifting and keep the schedule intact. A well run streetlifting platform never stalls, because the load sheet is always one attempt ahead.

Tied totals and athletes outside their category

When totals are equal the lighter athlete ranks first. The reasoning is simple, they produced the same result with less mass to carry. If bodyweights are identical too, the tie goes to whoever reached the total first, meaning the athlete who made the deciding lift on the earlier attempt.

Then there is the athlete who weighs in outside the category they registered for. It happens at every event. Two answers hold up, move them into their real category if it exists and has room, or let them lift outside the ranking with their loads still recorded. Decide before the event and write it in the rulebook. A ruling made at the scales, in front of the other entries, gets argued with every time.

Frequently asked questions

Yes, as long as the window is still open. It is common for someone sitting just over their limit. The last reading taken inside the window is the official bodyweight, and once the window closes nothing moves.
Yes, on the coefficient alone. It works for a small platform or for a first edition. What you lose are the mid-table podiums, and those are exactly what brings mid-sized athletes back.
The usual base is the weighted pull-up and the weighted dip. Many events add the squat, some add the weighted muscle up. Three movements fill a day comfortably, four need either a second platform or one category fewer.
With no official bodyweight there is no category and no coefficient, so no ranking. The standard rule is blunt, no weigh-in no ranking. Still plan to let them lift outside the ranking if they travelled, it costs little and it defuses the argument.
