Given the nickname "Five-Star Grilled Chicken," Menayothin has been dominant in his weight class. The 5’2" boxer hasn’t lost a professional boxing match since his debut in 2007. He’s held the strawweight belt for nearly six years and looks like he won’t be dropping it any time soon.

Notable minimumweight champions include Ricardo Lopez, Ratanapol Sor Vorapin, Jose Antonio Aguirre, Ivan Calderon, and Thammanoon Niyomtrong (also known as Knockout CP Freshmart, who has been the WBA champion since 2016).

Amateur weight classes also specify the minimum weight (which the same as the maximum weight of the next highest class). For safety reasons, fighters cannot fight at a higher weight. This also meant that even the heaviest weight class has a limit, albeit a lower bound. The lower limit for "heavyweight" was established in 1948 at 81 kg. When a new limit of 91+ kg was established in 1984, the name "heavyweight" was kept by the 81+ kg class, and the 91+ kg class was named "super heavyweight", a name not currently used in professional boxing.

MILWAUKEE — Rolando "Nano" Vargas has been a boxer for as long as he can remember. He started in the living room — with gloves up to his elbows — as his kneeling father taught him how to throw a punch. Now 23, Vargas is in the gym three times a day preparing for the fight he hopes kicks off a breakout year.

Estrada, the current king of the junior bantamweight division, has built his long-standing career on an impressive combination of skills and experience. However, some dangerous young fighters await to challenge him once he decides to return after he completed his trilogy with Roman "Chocolatito" Gonzalez with a majority-decision victory back in December.

When Crawford led the team out of the tunnel, he carried his custom-made championship belt with the "N" logo on the buckle, and he wore the No. 140 Nebraska jersey he got in 2017 when he became with the undisputed 140-pound champion by knocking out Julius Indongo in Lincoln.

In the sport of boxing, weight classes are categories that boxers compete in based on their weight. These weight classes ensure that boxers of similar size and weight are matched against each other, promoting fair and competitive fights. The purpose of weight classes is to prevent significant disadvantages in size and strength and to ensure the safety of the boxers.

Boxing weight classes ensure fair competition by preventing significantly larger boxers from fighting smaller ones. Boxing weight divisions are determined solely upon weight, not factoring in height or reach. In professional boxing, each weight division has its own champion.

The World Boxing Association (WBA) was founded in 1921 as the National Boxing Association (NBA), a national regulating body of the United States. On August 23, 1962, the NBA became the WBA, which today has its head office in Panama. According to WBA championship rules, when a champion also holds a title of one of the other three major sanctioning bodies in an equivalent weight division, that boxer is granted a special recognition of "Unified Champion", and is given more time between mandatory title defenses. The WBA Championships Committee and President may also designate a champion as a "Super Champion" or "Undisputed Champion" in exceptional circumstances; the standard WBA title is then vacated and contested between WBA-ranked contenders. When a WBA "Regular Champion" makes between five and ten successful defenses, he may be granted the WBA "Super" title upon discretion of a vote of the WBA's board of governors.

Sometimes called the junior cruiserweight or light cruiserweight division, light heavyweight has a limit of 175 pounds. One of the original eight "Glamour Divisions," light heavyweight traces its inception all the way back to the early 1900s.

With 17 weight classes in boxing light heavyweight division and four major sanctioning bodies that bestow world titles, keeping track of who holds each of the belts can be difficult -- especially when there are sometimes multiple titlists in each organization because of interim and secondary belts.

Elongated southpaw Kun-Tae Lee (8-0-1, 2 KOs; amateur mark 102-10), 140, successfully kept his Japanese 140-pound belt as he defeated Ryan Joshua Yamamoto (7-7, 1 KO), 139.25, by a unanimous decision (99-91 twice, 100-90) over ten on Saturday at Korakuen Hall in Tokyo, Japan. Lee, a Japan-based Korean who had scored sixty-two consecutive victories to make it a national amateur mark, was in command almost all the way, but the challenger occasionally showed his strong heart to withstand the champ’s faster and more accurate combos and gamely retaliated toe-to-toe, winning the fifth round. Despite his retaliation Lee swept the second half and had him at bay down the stretch. In the super light category, in Japan, the 5’11" Lee may face tough opposition in the future against WBA mandatory contender Ghanan-Japanese Andy Hiraoka (24-0, 19 KOs), OPBF and WBO AP ruler Daishi Nagata, unbeaten JBC contenders #1 Kotaro Sekine (9-0-1, 8 KOs) and #2 Mikyo Watarai (5-0, 3 KOs; amateur mark 77-15, 19 KOs).
