Division
Flyweight is the 125-pound division of mixed martial arts, and the lightest at which most men's promotions hold championships. Under the Unified Rules of MMA, a flyweight bout is contracted at a maximum of 125 pounds — 56.7 kilograms — with a one-pound allowance in non-title fights and none at all when a belt is on the line. Below it sits strawweight at 115 pounds; above it, bantamweight at 135.
Flyweight is the clearest demonstration that mixed martial arts is a technical sport before it is a physical one. Knockdown power is the exception rather than the rule, so fights are built rather than ended: angles are worked for, positions are earned, and the fighter who is still executing cleanly in the last minute usually wins. Watching a flyweight round is watching decisions being made at speed.
That has consequences for how careers look here. Durability matters less than consistency, because there are fewer single moments capable of erasing a lead. Fighters tend to stay competitive longer, and the gap between the top of the division and the middle of it is measured in small technical margins rather than in obvious physical advantages. It is also the division where a well-drilled grappling sequence is most likely to run to completion, since the strength disparities that stall exchanges at heavier weights are smaller.
Every fighter Fight Hub records in the flyweight division, with their professional record, the gym they train out of, their nationality and the measurements that make up their tale of the tape. Each name links through to a full profile. Records shown are professional records across all promotions, not a single organisation's tally.
Flyweight has the narrowest room below it and a heavily populated division above, which shapes where its fighters come from and where they go. The neighbouring division pages are listed below, alongside the countries and gyms that produce the most fighters at this weight.
