Zhang Weili, the first Chinese champion in Ultimate Fighting Championship history, did not ascend to the top of the strawweight division through sheer talent alone. Behind every highlight-reel finish, each championship belt, and each moment of poise under fire, there existed a network of training partners who forged her skills and tested her resilience. From modest gyms in Hebei Province to world-class camps in North America, the people who shared the mat with Weili played an indispensable role in crafting the fighter who would go on to defeat Joanna Jędrzejczyk in a Fight of the Year classic, survive a war with Yan Xiaonan, and reclaim her title from Carla Esparza. Understanding these relationships is key to appreciating not only her technical evolution but also the mental fortitude that defines her career. The athletes, coaches, and sparring partners who shaped her journey remain the unsung architects of her success.

Early Foundations in China: From Sanda to the Cage

Zhang Weili began her martial arts path at age nine, initially training in sanda under local coaches in Hebei. Her early training partners were fellow students at small, spartan gyms where equipment was scarce but motivation was high. These sessions were grueling, often featuring repetitive drills of straight punches, round kicks, and takedown defense. Weili often recounts that sparring against taller, heavier partners forced her to develop the head movement, angles, and footwork that later became hallmarks of her striking game. The camaraderie and competitive spirit among the group pushed her to refine her combinations under real pressure. Many of those early partners shared her dream of competing on the world stage, and their collective hunger created an environment of constant improvement.

When Weili transitioned to Brazilian Jiu-Jitsu, her training partners at the local academy introduced her to the ground game. Without a steady stream of high-level grapplers, she relied on drilling with anyone willing to train, from white belts to the occasional visiting purple belt. This scarcity only fueled her determination to learn. She would spend extra hours studying techniques online and then test them against her partners. A key figure during this period was her first BJJ coach, a Chinese black belt who had trained in Brazil, who often paired her with larger male students to simulate the weight and pressure she would face in competition. Those early ground partners taught her the fundamentals of guard retention, sweeps, and escapes—tools that would later allow her to survive and reverse top positions against world-class wrestlers. The loyalty and consistency of these local athletes provided a stable base that allowed Weili to develop at her own pace while building the work ethic that would later impress coaches at the world’s best camps.

Key Training Partners Who Shaped Her Style

As Weili’s reputation grew, she began seeking out specialized training partners who could elevate specific areas of her game. The following individuals and groups have been particularly influential throughout her career.

Joanna Jędrzejczyk: Rival Turned Training Ally

The relationship between Weili and Joanna Jędrzejczyk is one of the most compelling in modern MMA. Before their epic clash at UFC 248, Weili had long admired Jędrzejczyk’s striking precision and fight IQ. However, it was during the build-up to that fight—and in the aftermath—that the two shared training sessions. According to interviews, Jędrzejczyk’s willingness to spar with Weili helped the Chinese champion understand the timing, feints, and distance management of elite Muay Thai. Those sessions sharpened Weili’s defensive reactions against a fighter known for volume punching, lateral movement, and devastating body kicks. While their rivalry was fierce, the mutual respect forged in training became a foundation for techniques Weili would use in subsequent fights, including her successful title defenses. Jędrzejczyk’s feedback on clinch entries and knee positioning gave Weili new avenues to exploit taller opponents. Their partnership demonstrates that even the most intense competitors can push each other to new heights through shared training, and it remains one of the most inspiring examples of sportsmanship in MMA history.

Henry Hoof: The Grappling Architect

American coach Henry Hoof, known for his work with multiple UFC champions, became a pivotal figure in Weili’s development. Hoof’s expertise in wrestling and Brazilian Jiu-Jitsu addressed a key weakness in her early game: takedown defense and ground control. Under his guidance, Weili spent countless hours drilling defensive wrestling—sprawls, underhooks, escapes from bad positions, and the all-important ability to scramble back to her feet. The training partners Hoof provided included collegiate wrestlers and BJJ black belts who could simulate the relentless pressure of fighters like Carla Esparza or the chain wrestling of Rose Namajunas. One specific partner, a former NCAA Division I wrestler, would chain takedown attempts for five minutes straight, forcing Weili to stay composed and react without panic. Hoof emphasized that the best training partners are those who force you to think under duress. The result was a dramatic improvement in Weili’s takedown defense, which she showcased in her second fight against Namajunas by stuffing multiple shots and immediately returning to her feet. The hours spent with high-level grapplers through Hoof’s network directly translated to her ability to win rounds with superior scrambling and mat returns.

Local Sparring Partners: The Unsung Heroes

Throughout her career, Weili has consistently credited the everyday fighters and coaches in China who provided consistent, day-to-day training. Fighters such as Yan Xiaonan, a fellow strawweight contender, and other members of the Alliance Fighting Club in Beijing offered live rounds that simulated the chaos of competition. Yan, known for her pressure striking and takedown defense, was a particularly valuable partner because she forced Weili to work on her footwork and clinch entries against a similarly sized opponent. Other local partners included male flyweights who mimicked the movement and speed of Jędrzejczyk before the title fight, helping Weili prepare for that historic bout. Weili has stated that training with smaller, faster partners helped her timing, while work with larger athletes built her durability. One partner, a male bantamweight, would deliberately use awkward angles and showboating taunts to test Weili’s focus. The loyalty and dedication of these local athletes provided a stable base that allowed Weili to develop at her own pace, and they were among the first to celebrate her successes when she finally reached the UFC.

International Camp Teammates: A World of Styles

When Weili traveled to the United States for extended camps, she was welcomed by a host of elite fighters. At Team Alpha Male in Sacramento, she sparred with bantamweights and featherweights who tested her power and reach. Sessions with athletes like Cynthia Calvillo provided rounds of high-pressure grappling, while Andre Fili and other larger partners helped her work on fight-ending combinations. The gym’s emphasis on wrestling and scrambling gave Weili tools to neutralize opponents who tried to ground her. Meanwhile, at American Top Team in Florida, she was paired with fighters like Amanda Ribas, whose unorthodox striking and relentless takedown entries demanded constant adaptation. A particularly memorable partner was a male strawweight who specialized in imitating the drop-step level changes of wrestling-heavy opponents. Each new training partner added a layer of complexity to Weili’s preparation, forcing her to adjust her game plan from round to round. The diversity of these teammates prevented her from settling into predictable patterns and kept her growth curve steep. By the time she faced Carla Esparza for the second title, Weili had already trained with multiple wrestlers who mimicked Esparza’s grinding style, allowing her to implement her own takedown-heavy game plan with confidence.

Training Camps and International Exposure

Zhang Weili’s decision to seek training outside China marked a turning point. The shift began in 2017 when she attended camps in Thailand to refine her Muay Thai clinch work. There, she trained alongside local champions who emphasized destructive elbow strikes and knee traps—a skill set she later used to dismantle Jessica Andrade for the title. However, the real transformation came when she joined forces with established UFC camps abroad, each offering unique challenges and resources.

Team Alpha Male: Melting Pot of Technique

Under the roof of Team Alpha Male in Sacramento, California, Weili was immersed in a culture of relentless drilling and analytical breakdowns. Partners from various weight classes—many of whom were Division I wrestlers or decorated grapplers—demanded that she maintain high pace over five rounds. The gym’s head coach, Justin Buchholz, often paired her with fighters who could simulate the specific stylistic approaches of her upcoming opponents. For example, before her rematch with Namajunas, she worked with a partner who replicated Namajunas’s jab-first entry and sneaky left hook. Sessions with fighters like Paige VanZant (during her tenure at the gym) provided rounds of high-volume striking and creative submissions. The environment was competitive yet supportive, with partners willing to stay late to work on specific sequences—whether that meant drilling takedowns off the cage or practicing escapes from side control. This culture of collaboration allowed Weili to refine the details that separate good fighters from great ones. The analytical approach at Team Alpha Male helped her break down her own weaknesses objectively, turning training into a continuous loop of feedback and adjustment.

American Top Team: Strength in Numbers

In Florida, the American Top Team facility offered a different style of training. With a roster featuring dozens of UFC athletes, Weili could spar with fresh opponents every round. The diversity at ATT meant she faced boxers, wrestlers, BJJ specialists, and kickboxers within a single session. This simulated the unpredictable nature of MMA fights better than any single-styled gym. Her partners there included Amanda Ribas, who provided a tricky, unorthodox striking style, and other strawweights who drilled takedown entries for hours. A particularly valuable partner was Katlyn Chookagian, whose volume punching and lateral movement forced Weili to work on her head movement and counter-striking. The volume of rounds—sometimes eight to ten five-minute rounds per day—helped Weili’s cardio reach elite levels, a factor that proved decisive in the later stages of her fights. Coaches at ATT noted that her ability to adjust mid-fight was a direct result of the mixed competition she faced daily. She learned to read tells, anticipate entries, and counter against opponents who were constantly changing their approach. The experience made her a more complete fighter, capable of winning fights by knockout, decision, or even submission if necessary.

The Role of Strength and Conditioning Partners

Beyond the mat, training partners in strength and conditioning rooms contributed to Weili’s durability and explosiveness. Push-pull drills, sprint intervals, and resistance training with partners who could monitor form and intensity helped her maintain peak physical condition without overtraining. One strength coach in China had her train with a partner who would hold pads while she performed explosive squat jumps, ensuring she generated maximum power from her hips. In the US, she worked with a partner who specialized in yoga and mobility, helping her recover faster between sessions. These partners, often professional trainers themselves, ensured that her explosive power—so crucial to her knockout ability—was balanced with recovery and flexibility. Their consistency allowed Weili to survive the high-volume exchanges that defined her war with Jędrzejczyk, a fight where conditioning made the difference in the later rounds. Additionally, diet and nutrition partners helped her maintain weight cut strategies that minimized strength loss while allowing her to perform optimally.

Mental Toughness Forged Through Partnership

Technical improvements are only part of the story. Training partners also shaped Zhang Weili’s mental toughness—the intangible quality that separates champions from contenders. Throughout her career, she has faced adversity, including her loss to Rose Namajunas and the subsequent pressure to reclaim the title. The partners who had been with her through victories were equally present during those setbacks. They reminded her of the preparation that had brought her to the top and helped her analyze errors without self-blame.

Weili has often spoken about the role of trust in her training partnerships. Knowing that a partner will not intentionally harm her but will push her to the brink creates a safe yet intense environment. This trust allows her to simulate fight scenarios where fatigue and pain are real, building the psychological armor needed for championship rounds. One specific partner, a former kickboxer with a relentless pressure style, would intentionally scream and taunt during sparring to mimic the mental games of opponents like Namajunas. Weili learned to stay calm, block out distractions, and focus on her game plan. Training partners who challenge her mindset—calling her out when she takes shortcuts or encouraging her after a hard loss—are as valuable as those who teach technique. The mental resilience she displayed in her second fight against Namajunas—where she came close to winning via submission and outstruck her opponent for significant stretches—stemmed directly from the honest, constructive environment cultivated by her training partners. They helped her convert setbacks into learning opportunities, reinforcing a growth mindset that has defined her professional journey.

Furthermore, sparring partners who have fought her in preparation for bouts provide critical feedback on what works and what doesn’t. For example, during camps for the Namajunas rematch, partners who had studied her first defeat helped her adjust her guard and improve her clinch entries. They noticed that she tended to drop her right hand when thrown off balance—a flaw they forced her to correct through repetition and live scenarios. This collaborative approach turned theoretical adjustments into ingrained habits. The trust and mutual investment between Weili and her partners allowed her to expose weaknesses in training without fear of judgment, a vulnerability that ultimately accelerated her growth. The mental fortitude she now possesses is a direct result of years spent in an environment where honest feedback was paired with unwavering support.

Legacy and the Future of Zhang Weili’s Training Partnerships

As Zhang Weili continues to compete at the highest level, her approach to training partners evolves. She now has the resources to bring hand-picked athletes from across the globe to her own camps, and she often reciprocates by inviting potential champions to train alongside her. This creates a reciprocal ecosystem where she gives back to the community that fostered her growth. In 2023, she established a training facility in Beijing with the goal of providing Chinese fighters with the same high-level competition she found abroad. The gym already features a rotating cast of international fighters, including top bantamweights and strawweights who cross-train during fight camps. Weili has also started mentoring younger Chinese fighters, such as Rong Zhu and Liu Pingyuan, sharing the techniques and mindsets she learned from her own partners. Her story underscores a truth often overlooked in individual sports: no champion trains alone. The hands that shape the guard, the feet that check the kicks, the voices that call the drills—these are the unsung architects of greatness.

For Zhang Weili, the journey from a small gym in Hebei to UFC gold was paved by the dedication of training partners who saw her potential and helped her realize it. As she eyes further titles and perhaps a second championship reign, the foundation built with these partners will remain the bedrock of her success. Their influence extends beyond her own career, inspiring a wave of new athletes in China who understand that true progress demands a community of hungry, honest partners. The future of Chinese MMA will be built on the same principle: that collaboration, not isolation, is the path to greatness.
