Lightweight

Lightweight is the 155-pound division of mixed martial arts, and the one most often described as the deepest in the sport. Under the Unified Rules of MMA, a lightweight bout is contracted at a maximum of 155 pounds — 70.3 kilograms — with a one-pound allowance in non-title fights and no allowance at all when a belt is on the line. It sits directly between featherweight, capped at 145 pounds, and welterweight, capped at 170.

What defines the division

Depth is the word that follows lightweight everywhere, and it is not a compliment paid lightly. The weight suits a large share of the adult male population without extreme cutting, which means the talent pool feeding it is wider than in any division above or below. The practical consequence is competitive: a fighter can put together a long unbeaten run at 155 pounds and still be several wins away from a title shot.

Style follows from that crowding. Lightweight rewards fighters who are complete rather than specialised — a one-dimensional wrestler or a pure striker tends to find a counter quickly. Speed and cardio matter more here than raw power, and fights are more likely to be decided over three rounds of accumulated work than by a single exchange. Weight cutting is a discipline of its own at 155: many lightweights walk around ten to fifteen pounds above the limit, and how well a fighter rehydrates is often as decisive as anything that happens in training camp.

What you will find on this page

Every fighter Fight Hub records in the lightweight 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 — a fighter who has competed outside a major promotion carries those results here too.

Where to go next

Fighters move between weight classes over a career, and lightweight sits on a busy border: featherweights step up, welterweights come down. The neighbouring division pages are listed below, alongside the countries and gyms that produce the most fighters at this weight.
