Jon Crosby is the ladies man. He is a slick-pimp talking, swag walking type with a heart of gold. The ladies definitely swoon to him in hopes of more than personal training, but Jon still manages to run his business successfully. He is the ultimate Michael Jackson fan and manages to infuse the Jackson’s spirit in his training method and group classes. Youth are drawn to his high paced youth boxing class. Jon is also an aspiring professional boxer, who now in his 30’s, still has hopes of being the next Roy Jones. CJ and Jon have had their differences in the past but after nearly losing his life the two have put their difference aside and became brothers.
