Dave Rienzi is an American professional bodybuilder, strength and conditioning coach, and fitness entrepreneur best known for training Dwayne “The Rock” Johnson. He has worked with major Hollywood actors, including Henry Cavill, and helped develop the physiques audiences recognize from blockbuster films. Beyond celebrity fitness, Rienzi has built his own coaching business, earned IFBB professional status, and co-founded ZOA Energy.
His marriage to entertainment executive Dany Garcia also connects him to one of Hollywood’s most successful business partnerships. From his early interest in weightlifting to his professional bodybuilding achievements, Rienzi has developed a career that combines exercise science, athletic performance, and entrepreneurship.
Who Is Dave Rienzi?
Dave Rienzi is a fitness specialist who combines competitive bodybuilding experience with academic training in human movement and exercise science. He founded Rienzi Strength & Conditioning and became widely recognized through his long-term professional relationship with Dwayne Johnson, which began in 2012.
Unlike trainers who focus exclusively on physical appearance, Rienzi designs programs around muscle development, functional movement, recovery, and the physical demands of his clients’ careers. His work with film actors requires him to balance muscular size with the stamina and mobility necessary for lengthy shooting schedules.
He also maintains his own career as a competitive athlete rather than working exclusively behind the scenes. His bodybuilding achievements include earning an IFBB Pro card in 2020 and participating in professional Classic Physique competitions during 2024 and 2025.
Dave Rienzi’s Early Life and Education
Dave Rienzi was born on April 25, 1984, in the United States. His interest in fitness began at age 12, when he started lifting weights using equipment that his father kept in the family basement.
Those early workouts introduced him to the process of building strength through repeated physical effort. As his interest developed, he began exploring bodybuilding and the relationship between exercise, muscular growth, and human performance.
Rienzi eventually attended Indiana University, where he earned a Bachelor of Science degree in kinesiology with a specialization in fitness. His education helped him understand biomechanics, muscular function, physical conditioning, and how exercise influences human movement.
After graduation, he spent several years working in the fitness industry and developing practical coaching experience. In 2014, he opened a private training facility, establishing the foundation for his own strength and conditioning business.
Dave Rienzi’s Bodybuilding Career
Dave Rienzi pursued competitive bodybuilding before his celebrity coaching work brought him international recognition. Competing gave him firsthand experience with strength development, contest preparation, nutrition, and the demands of presenting a competition-ready physique.
His early competitive record includes a first-place finish in the light-heavyweight division at the 2011 NPC All South Championships. He also finished fourth in the heavyweight division at the 2014 NPC National Championships, demonstrating his ability to compete against experienced amateur bodybuilders.
Earning His IFBB Pro Card After Four Surgeries
Rienzi’s bodybuilding journey included significant physical setbacks that interrupted his competitive ambitions. He underwent four operations, including two rotator cuff surgeries and two knee surgeries, before returning to the competitive stage.
During rehabilitation, he developed a stronger interest in muscular activation and the movement patterns that can change after injuries. He incorporated that experience into his training philosophy, particularly when working with clients who needed to build muscle without aggravating existing physical limitations.
His comeback culminated in 2020 when he earned his IFBB Pro card, a major milestone in competitive bodybuilding. This achievement gave him professional status after years of training, competition, and recovery.
Professional Bodybuilding Results in 2024 and 2025
Rienzi continued pursuing bodybuilding after reaching professional status, competing in the Men’s Classic Physique division. At the 2024 IFBB Texas State Pro, he finished fifth in the open division and second in the Masters 40+ competition.
He returned to professional competition at the July 2025 Chicago Pro, where he placed ninth in the open Classic Physique division. He also earned third place in the Masters 40+ division at that event, demonstrating his continued involvement in the sport while maintaining his coaching and business responsibilities.
How Dave Rienzi Became Dwayne Johnson’s Trainer
Dave Rienzi began working with Dwayne Johnson in 2012, when Johnson was expanding his Hollywood career while maintaining his involvement in professional wrestling. Dany Garcia, who was managing Johnson’s career at the time, helped bring Rienzi into his fitness team.
Garcia wanted a specialist who understood bodybuilding, biomechanics, nutrition, and the physical challenges associated with demanding film schedules. Rienzi’s education and bodybuilding experience suited those requirements, and the two men quickly established a productive working relationship.
Their early collaboration involved preparing Johnson for WWE appearances, including WrestleMania. As Johnson’s acting career developed, Rienzi took on a larger responsibility for his physical conditioning and movie-specific transformations.
The partnership eventually expanded beyond conventional personal training into long-term performance management. Rienzi began coordinating exercise programs, nutritional adjustments, and recovery strategies around Johnson’s professional commitments.
Dave Rienzi’s Work on Dwayne Johnson’s Movie Transformations
Some of Dave Rienzi’s most demanding coaching assignments have involved preparing Dwayne Johnson for physically challenging film roles. Each project required different muscular proportions, conditioning targets, and performance capabilities.
Hercules (2014)
For the 2014 film Hercules, Rienzi helped Johnson follow a demanding bodybuilding program that emphasized muscle size and definition. The preparation involved approximately six months of structured training, with particularly intense workouts during the final stages.
Johnson suffered serious injuries during his WrestleMania 29 match against John Cena, including torn muscles and hernia-related complications. Rienzi adjusted the training and nutrition strategy during Johnson’s recovery, helping him preserve his physique before filming resumed.
Black Adam (2022)
The superhero film Black Adam presented another challenge because Johnson wanted a muscular appearance that would translate convincingly on screen. Rienzi designed a training approach emphasizing muscular fullness, definition, controlled repetitions, and targeted development.
The workouts incorporated carefully planned chest, back, shoulder, arm, and leg sessions alongside cardiovascular conditioning. Rather than relying exclusively on heavier weights, Rienzi used controlled movements to increase muscular tension and limit unnecessary stress on Johnson’s joints.
The Smashing Machine (2025)
For The Smashing Machine, Rienzi helped Johnson recreate the physical appearance of former mixed martial arts champion Mark Kerr. Director Benny Safdie wanted the actor to develop a particularly imposing physique, with noticeably larger shoulders and trapezius muscles.
Rienzi spent approximately five to six months preparing Johnson for the role while coordinating around his wrestling commitments. He introduced additional shoulder training, increased the volume of specific exercises, and emphasized posterior-chain strength to preserve explosive movement.
He also worked with Johnson during filming in Vancouver, adjusting his conditioning and nutrition around the physical demands of fight scenes. The project demonstrated how Rienzi could adapt bodybuilding methods to portray a real athlete while maintaining the mobility necessary for convincing screen performances.
Dave Rienzi’s Work With Henry Cavill
Although his partnership with Johnson attracts the most attention, Dave Rienzi has also worked with British actor Henry Cavill. Cavill has discussed Rienzi’s involvement in managing his exercise routines, dietary adjustments, and overall physical preparation.
During his work on The Witcher, Cavill followed training programs that balanced muscular development with the energy demands of acting and stunt work. Rienzi helped him adjust the amount of protein, carbohydrates, and fats he consumed according to filming requirements and physique goals.
Cavill has also described consulting Rienzi about the reasoning behind particular nutritional decisions rather than simply following instructions. Their relationship highlights another aspect of Rienzi’s coaching career: helping actors understand their training while adapting programs to different production schedules.
Dave Rienzi’s Training Philosophy and Workout Methods
Dave Rienzi approaches strength training through a combination of bodybuilding principles, exercise science, and individualized programming. He emphasizes progressive development rather than expecting clients to achieve dramatic transformations through uncontrolled workout intensity.
Biomechanics and Muscle Activation
Biomechanics plays an important part in Rienzi’s training philosophy because it examines how muscles, joints, and movement patterns interact during exercise. He considers the way clients perform individual movements before deciding how much resistance or training volume they should use.
His rehabilitation experiences also influenced his interest in muscle activation, particularly when injuries affect normal movement. He incorporates mobility work, targeted exercises, and movement assessments to address weaknesses and reduce unnecessary strain during training.
Consistency, Nutrition, and Recovery
Rienzi encourages clients to maintain manageable exercise and nutrition habits rather than repeatedly switching between extreme dieting and intense workout programs. For actors, this approach helps preserve an established fitness level between film projects.
Nutrition also changes according to the desired physical outcome, with adjustments to calorie intake and macronutrient balance. Recovery remains equally important because sustained muscle development requires sufficient rest and an appropriate balance between training volume and physical stress.
His personal training routine has included six weekly workout sessions, with time dedicated to major muscle groups and cardiovascular exercise. However, his coaching approach prioritizes individual needs rather than requiring every client to follow his own schedule.
Dave Rienzi’s Wife: Who Is Dany Garcia?
Dave Rienzi married Dany Garcia on March 29, 2014. Garcia is an American entrepreneur, film producer, investor, and former professional bodybuilding competitor who has developed businesses across entertainment, sports, and consumer products.
Their marriage attracts considerable public attention because Garcia was previously married to Dwayne Johnson. Despite that history, Garcia, Johnson, and Rienzi have maintained overlapping professional relationships in the entertainment and fitness industries.
Dany Garcia’s Career Before Marrying Dave Rienzi
Garcia was born on November 29, 1968, and grew up in a family with Cuban immigrant roots. She studied finance and marketing at the University of Miami before beginning her professional career in the financial industry.
She joined Merrill Lynch in 1992 and later built experience in financial management and entrepreneurship. Her business background eventually helped her transition into talent management, entertainment production, and brand development.
In 2008, Garcia began managing Johnson’s career after their marriage had ended. She subsequently co-founded Seven Bucks Productions with him in 2012, creating a company that would develop major film and television projects.
The production company’s credits include Jumanji: Welcome to the Jungle, Red Notice, and Jungle Cruise. Garcia also expanded her business activities through The Garcia Companies, while maintaining her own involvement in professional bodybuilding.
Dany Garcia’s Previous Marriage to Dwayne Johnson
Dany Garcia met Dwayne Johnson while they attended the University of Miami, and they married on May 3, 1997. The couple welcomed their daughter, Simone Alexandra Johnson, in August 2001 before announcing their separation in 2007.
Their divorce became final in 2008, but they continued working together and eventually expanded their professional partnership. When Garcia later married Rienzi, the three developed an unusual arrangement in which personal family history and professional collaboration coexisted.
Johnson has publicly discussed the emotional difficulties of the divorce and the effort required to rebuild a productive relationship with Garcia. Their continued business partnership helped create the environment in which Rienzi became both Johnson’s trainer and Garcia’s husband.
Dave Rienzi’s Family Connection to Simone Johnson
Through his marriage to Garcia, Dave Rienzi became part of the family circle that includes her daughter, Simone Johnson. Simone pursued a career in professional wrestling, following the traditions of her father Dwayne Johnson and his wrestling family.
She joined WWE’s developmental system in 2020 and later performed under the ring name Ava Raine, eventually shortening it to Ava. In January 2024, she became the general manager of WWE’s NXT brand after previously appearing as an on-screen wrestling personality.
On January 30, 2026, Simone announced that she would leave WWE after deciding not to renew her contract. Her departure marked a new phase in her professional life following several years of involvement in wrestling and television appearances.
Simone is Garcia and Johnson’s daughter, not Rienzi’s biological daughter. Rienzi has kept most details about his own family life private, and no publicly verified information establishes that he has biological children.
Other Family Connections
Rienzi’s marriage also connects him to Hiram Garcia, Dany Garcia’s brother and a film producer associated with Seven Bucks Productions. Hiram serves as the company’s president of production and has worked on major projects involving Johnson.
These family and professional relationships extend beyond fitness into movie production and business management. Rienzi’s own contribution, however, remains primarily connected to athletic conditioning, bodybuilding, and fitness-related ventures.

Conclusion
