Welterweight

Welterweight is the 170-pound division of mixed martial arts, and the one that most rewards being complete rather than exceptional at any single thing. Under the Unified Rules of MMA, a welterweight bout is contracted at a maximum of 170 pounds — 77.1 kilograms — with a one-pound allowance in non-title fights and none at all when a belt is on the line. It sits between lightweight, capped at 155 pounds, and middleweight, capped at 185.

What defines the division

Welterweight is where power and speed meet on roughly even terms. Below it, pace and volume tend to decide fights; above it, a single clean shot can end one at any moment. At 170 pounds both are true at once, and that combination shapes the fighters who last here: durable, positionally sound, rarely one-dimensional.

The division has long been associated with wrestling, and not by accident. At this weight, athletes are heavy enough to hold a position and fast enough to chain attempts, which makes control a viable path to victory rather than a holding pattern. The counter has developed alongside it — welterweight strikers tend to be defensively organised, comfortable fighting off the fence, and patient with their output. Fights here are often decided by who imposes the shape of the exchange, not by who lands the heavier single blow.

What you will find on this page

Every fighter Fight Hub records in the welterweight 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

Welterweight sits on two busy borders: lightweights moving up as their cuts become unsustainable, middleweights coming down in search of a speed advantage. The neighbouring division pages are listed below, alongside the countries and gyms that produce the most fighters at this weight.
