With over 17 years of professional experience,

Jon “The Cobra” Crosby is a NASM, NECP and IFA Certified personal trainer and professional athlete. He has been an avid boxer for over 17 years and has trained dozens of up and coming boxers and other athletes as well.

​

Having trained in several different sports including 5 different martial arts, Jon has become a well-rounded athlete, which reflects his character and humble upbringing. His interest in personal training transcended once he saw the positive and life changing impact that it could have on a person’s life.    

Early on he credits Mackie Shilstone, who is responsible for training both Roy Jones Jr. and Bernard Hopkins, as 

his  influence. Several  years  ago  Jon  launched  Cobra Crosby  Fitness,  which  is  his  own  personal  training and  boxing  training  company  aimed  at  helping  people from  all  walks  a  life  achieve  their  goals  no  matter the obstacles.
