My Pursuit as an unconventional strength training practitioner began in my career as an amateur fighter I started training with kettlebells and mace and clubs about 6 years ago. Since then achievements has been 2 ton owner Classics champion 1 time Olympia Expo champion in Las Vegas  as well as my first kettlebell Competition winner in Vegas. I won the club competition at the Arnold’s in 2017. I have multiple certifications and Club and mace. Going to Las Vegas what is the turning point in my unconventional strength training career. This year in Ohio the competition was tough, lots of new players very strong guys. I was fortunate to come out the winner this time. Training is my life. Time with my family is very important because I’m very Hands-On with my son he is the world to me I love spending time with my wife. But at the end of the day I’m in the gym pushing staying a hundred percent. I will keep pushing myself beyond the limits that’s for the kid’s success in my opinion. I have an accomplished class and have trained champion mace lifter, Alex Johnson, the youngest competitor so far he won a gold medal in Ohio this year has first competition in mace. I look forward to many more years of competition and training. I am very blessed for the family, friends and colleagues and students I have in my life.  I give  the glory to God tell him it would not be possible
