Tim Sullivan

Tim is a disabled veteran who has undergone multiple surgeries and relies on the aid of a prosthetic brace. Not satisfied with “no” for an answer and tired of hearing doctors tell him what his physical limitations would be, he decide to find a way to work around his injuries and strengthen his body and mind.

Tim started his transformational journey in 2007 and shed nearly 40 pounds of fat off of his body. One of the tools he incorporated into his arsenal was the use of kettlebells. He has been training with them ever since.

Tim first became HKC certified in order to properly train and help others learn the value of kettlebells. Not satisfied and definitely bitten by the Kettlebell bug, he became SFG certified to advance his teaching skills and grow his knowledge of the kettlebell.

What Ludus Vos Means

Ludus Vos is a combination of two words that are rooted in ancient Roman culture. The word ludus was used to name schools, games and gladiator training facilities. Vos means YOU and around the 5th century was used to respectfully address the Roman Emperor. Together, Ludus Vos is the school of YOU, the game of YOU and the training of YOU.

SFG Certification

StrongFirst Certification

Learning from a StrongFirst Certified Instructor is learning from the best.

Over a decade ago our predecessor, RKC kettlebell certification, shook up the complacent trainer education industry with a previously unheard of practice. Instead of letting their graduates off the hook with multiple-choice questions, RKC subjected their instructor candidates to a “martial arts belt test.” To earn a coveted RKC certificate a student had to demonstrate perfect exercise technique, have his or her spirit tested in grueling workouts, pass strength tests, and demonstrate teaching skills with a volunteer from the general public. “Walking the walk” was the only way to earn the “RKC” designation.

Among RKC graduates are world champion athletes, special operators, elite coaches, medical professionals, and other hardcore types committed to serious training. Not surprisingly, the RKC course was extremely demanding mentally and physically, required extensive preparation, and, in spite of the high caliber of the individual it attracted, typically failed 30% of the students. In one in-house certification for a government agency, the failure rate was a record 82%—because the organization had not taken the warning about the elite nature of the course seriously.

Never content with being the best, RKC kept constantly polishing the chrome, collaborating with top scientists, medical professionals, and coaches like Professors Stuart McGill and Tom Fahey, Gray Cook, and Dr. John DiMuro.  In a little over a decade, the RKC instructor manual has seen 24 editions.

StrongFirst was started by Pavel Tsatsouline who developed the RKC curriculum and led the RKC organization on the field. StrongFirst has preserved the best RKC standards and traditions and it continues to improve on them. Consider that in order to graduate from our bodyweight training instructor course, a student must be able to do a strict one-arm pushup—and that is the ladies’ standard. When we say “strength,” we mean StrongFirst.
