In the 2016 Summer Olympics, Diaz won the silver medal in the women's 53-kg weight division, the first Filipino to win a medal in a non-boxing event since 1936 and ending the Philippines' 20-year Olympic medal drought. At the 2020 Summer Olympics, Diaz became the country's first Olympic gold medalist. She also set Olympic records for the 55 kg division in the clean and jerk at 127 kg and in the total at 224 kg.

Early life and education Hidilyn Francisco Diaz is the fifth of six children of Eduardo and Emelita (née Francisco) Diaz. Her father was a tricycle driver before becoming a farmer and a fisherman. She grew up wanting to be a banker and trying several sports, like basketball and volleyball. Her cousin, Allen Jayfrus Diaz, taught her the basics of weightlifting.

Diaz attended the Zamboanga A.E. Colleges (later Universidad de Zamboanga; UZ) for her high school studies under a scholarship. In college, she pursued a bachelor's degree in computer science at the same school. She then stopped attending the university as a third year irregular student as she found her degree unsuitable for her. She also claimed that it distracted her training. After her success in the 2016 Olympics, Diaz decided to continue her tertiary education and intended to pursue a degree related to sports in Manila.

In January 2017, Diaz received a scholarship to study business management at De La Salle-College of Saint Benilde.

In 2019, Diaz took a leave of absence from her schooling while she focused on preparation for the Olympics after winning the Asian Games. In 2020, Diaz re-enrolled into online classes because the 2020 Summer Olympics were postponed to July 2021 due to the COVID-19 pandemic.

In July 2023, Diaz graduated from Saint Benilde and earned her business management degree.

In October 2024, Diaz enrolled in a short course, the Athlete Career Transition Sports Ethics and Integrity at KU Leuven in partnership with the International Olympic Committee Solidarity in Belgium.

In 2025 she completed a culinary course while continuing to manage her weightlifting academy.

Competitive career First learning weightlifting from her older cousins, Diaz initially lifted using makeshift barbells made of mag wheels or concrete. Prior to high school, Diaz joined the University of Zamboanga's (UZ) extension program to train in weightlifting under her cousin Catalino Diaz who was also her first coach. Elementary students not enrolled in UZ were able to train under the program of Institute of Human Kinetics director Elbert Atilano. She had to do part-time work to fund her transportation to a local gymnasium. Her part-time jobs were selling vegetables and fish and washing jeepneys. Diaz's first competition was the 2002 Batang Pinoy in Puerto Princesa. She went on to compete in various local and national competitions and secured support from the local government. Diaz became part of the Philippine national weightlifting team at age 13.

2012 Summer Olympics Diaz became the first Filipina weightlifter to compete in two consecutive Olympics, by qualifying in the women's weightlifting under 58 kg through the Continental and World Qualifying Tournaments. She was ranked ninth in her event heading to the Olympics. During the 2012 London Olympics, Diaz was chosen to be the flagbearer during the Opening Ceremony.Bolante, Mikkel (July 30, 2012) Filipino flag-bearer Hidilyn Diaz begins Olympic weightlifting campaign , InteraksyonHidilyn Diaz . sports-reference.comPhilippines . sports-reference.com

She successfully lifted a personal best of 97 kg in the snatch, 12th best among the 19 competitors. However her 118 kg clean and jerk was unsuccessful after three attempts. She was one of two competitors (along with Lina Rivas of Colombia) to end with an official result of "Did not finish" (DNF) in the event.

2015 to 2016 season

Diaz weighed around 56.28 kg during her first Olympic campaign, making her the lightest among competitors. Come the 2012 Olympics, she had increased her weight to 57.70 kg but still struggled making it to the top half of the competition. Trying to improve her chances of landing a podium finish at the 2016 Rio Olympics, Diaz decided to drop weight from under 58 kg to under 53 kg. This proved to be effective as she won the gold medal in the 1st Southeast Asian Weightlifting Championship in Bangkok. In that competition, she managed to lift a 98 kg snatch and a 115 kg clean and jerk for a 213 kg total. The same mark was also good for 4th place later on in the 2012 London Olympics.

In the Asian Weightlifting Championships, Diaz won both a gold medal in 2015 and a bronze medal in 2016. She also earned three bronze medals for the clean, jerk and snatch events in the 53 kg division of the IWF World Weightlifting Championship held in Houston, Texas, on November 22, 2015, to claim a spot in the 2016 Rio Olympics.

In March 2016, Diaz dominated the women's 58 kg event of the 2015-16 Philippine National Games National Finals held at Lingayen Town Plaza, Lingayen, Pangasinan, with a 92 kg snatch and 120 kg clean and jerk (new personal best) combined into 212 kg.

2016 Summer Olympics In the 2016 Summer Olympics in Rio de Janeiro, Diaz competed in her 3rd consecutive Olympics in the women's 53kg weightlifting category with the intention of at least winning a bronze medal. Diaz surpassed her own personal target and won the silver medal at the event, after successfully clinching a lift of 88 kg in her second attempt in snatch event (placed 6th) and 111 kg and 112 kg in the first and second attempts in the clean and jerk event (placed 2nd). This was the first medal for the Philippines in the Summer Olympics after 20 years. This was also the first non-boxing medal for the nation since 1936. Aside from being the first Filipina weightlifter to compete in three consecutive Olympics, she also became the first Filipino woman and the second person from Zamboanga and Mindanao to win an Olympic medal (after Simeon Toribio, bronze medal winner of men's high jump in the 1932 Los Angeles Olympic Games).

2018 Asian Games Diaz participated in the women's 53 kg event in the 2018 Asian Games in Jakarta, Indonesia. Two months prior to the Asian Games, she recruited Gao Kaowen who was previously coach of the Chinese national women's army team. In the women's 53 kg in the 2018 Asian Games, Diaz had a total lift of 207 kg, beating Turkmenistan's Kristina Shermetova (206 kg) and Thailand's Surodchana Khambao (201 kg) to deliver the Philippines' first gold in the 2018 games, as well as being the first Filipino weightlifter of any gender to win a gold medal in the Asian Games.

2019–20 season After winning a bronze in the 2017 World Championships, Diaz again won a bronze in the 2019 edition of the same event. She also won a silver in the 2019 Asian Championship, and another gold in the 2019 Southeast Asian Games in Manila. In January 2020, Diaz won the gold medal in the women's 55 kg event at the Roma 2020 World Cup in Rome, Italy.

2020 Summer Olympics On July 26, 2021, Diaz won a gold medal at the 2020 Summer Olympics in Tokyo. This was the first ever gold medal won by a Filipino athlete since the country's first appearance in the Olympics in 1924. She set new Olympic weightlifting records by lifting 127 kg in the clean and jerk and lifting a total weight of 224 kg.

Diaz's achievements at the 2020 Summer Olympics were impressive, as she was previously stranded in Malaysia from February 2020 until July 2021, due to travel restrictions imposed by governments to contain the COVID-19 pandemic. Based on guidance by her coach, Gao Kaiwen, Diaz initially went to train in Malaysia in February 2020 because Gao thought it would be better for her as she focused on qualifying for Tokyo. However, once Malaysia implemented its Movement Control Order in April 2020, which closed gyms within the capital region of Kuala Lumpur (Klang Valley), she improvised by using bamboo sticks and large water bottles as makeshift weightlifting equipment. In October 2020, she relocated to the southern coastal state of Malacca where they had been living in a house owned by a Malaysian weightlifting official in Jasin. The Malaysian government then implemented periodic restrictions on gyms and sporting activities within 2021 (to reduce social interaction and contain the spread of the coronavirus), forcing her to work out in the house's sweltering open-air carport in the immediate months prior to the 2020 Summer Olympics.

Diaz also struggled with her mental health during this ordeal, especially with the postponement of the 2020 Olympics, and credited her team, including sports psychologist Dr. Karen Katrina Trinidad and Project: Steady with trauma therapist Gang Badoy Capati for her well-being. She also kept busy during her training overseas during COVID-19 lockdown by cooking, attending meetings, and studying.
