Dr. Mark Cheng is the chief instructor of KettlebellsLosAngeles. He has trained extensively as a private, direct student of Pavel Tsatsouline weekly for years, and earned his RKC rankings directly from Tsatsouline himself. Dr. Cheng has been enthusiastically pursuing kettlebell training as a means of rehabilitation and health ever since he experienced the successful rehabilitation of his own lower back and shoulder injuries with Russian kettlebells. He also dropped 20 pounds after becoming regularly involved with kettlebell training!

No ordinary private trainer, Dr. Cheng brings extensive medical knowledge as a specialist in Chinese medicine orthopedics to each and every one of his clients and students. Always looking to increase his knowledge and understanding of the rehabilitative and prehabilitative applications of kettlebell training and the RKC system, Dr. Cheng attended the 2007 RKC Level 2 Certification, which focused on Functional Movement Screen technologies as presented by Sr. RKC, Brett Jones, as well as many other therapeutically applied movement sciences taught by international level coach Mark Reifkind, Sr. RKC, Danish researcher Kenneth Jay, Sr. RKC, and Andrea DuCane, Sr. RKC. This marked the second time Dr. Cheng was exposed to Gray Cook's Functional Movement Screen, as Gray Cook himself presented the screen to him and Pavel Tsatsouline privately at the David Beckham Soccer Academy.

Using kettlebell and RKC rehabilitation technologies, Dr. Cheng has helped many individuals overcome conditions such as chronic lower back pain, rotator cuff pathologies, and obesity. On an elite level, he has worked with professional athletes, law enforcement and military personnel, and celebrities, as well as assisting his mentor, Pavel Tsatsouline during the Russian Kettlebell Challenge Instructors Courses and Tactical Strength Courses. Dr. Cheng is currently working with the FBI - Los Angeles office as their kettlebell instructor, as well as the world famous Inosanto Academy of Martial Arts and several other athletic and medical groups.

Dr. Cheng's teaching method reflects an eye towards progressive detail, safety, constant improvement, and fun.
