Mike Rattenni (IFBB PRO)

Head Pro Competition Coach
Michael Rattenni has been involved in the fitness industry for twenty plus years. A New York native, he moved to the birthplace of bodybuilding and began his fitness career as a personal trainer in California. He quickly worked his way up in management and has since developed and built personal training and fitness manager systems in over 450 locations and health clubs and top franchises- World’s Gym, Gold’s Gym, Retro Fitness, and Crunch Fitness to name a few.
In 2014 he began managing top social media influencers and athletes worldwide, providing a platform for them to take their careers to the next level. Using his experience and contacts in the industry, he was able to leverage their value and marketability, negotiating contracts in a post-fitness magazine era where big contract deals and sponsorships were hard to land.
In 2015, after 15 years off from competing, he stepped back in the competitive circuit to pursue his pro card in the newly introduced Mens Physique division. Within one year, he accomplished being an undefeated masters amateur and won his pro card after competing in just three shows total at North Americans in 2016. Soon after he was on the pro stage going toe-to-toe with the best in the world.
In 2016, Michael shifted his focus, knowing his legacy and impact in the industry would be even greater as a coach than a competitor himself. He set his goal to recruit fresh, new talent, introducing many to the NPC/IFBB and created what is now known as Unchained Physiques.
Over 200 plus top five placings in the NPC/IFBB and OCB, 35 overall wins and captured pro cards at every NPC national show aside from one thus far, as well as turning natural athletes pro in both federations, Michael has established himself as one of the top fitness gurus in the nation.

Kaveh Mehrabi

Head Posing Coach

I want to welcome everyone to Unchained Physiques. I’ve been an athlete my whole life ever since I’ve been old enough to walk. Played soccer and basketball growing up. I’ve always loved and respected the sport of bodybuilding and in 2018 I decided to compete in my first competition in Charlotte, NC where I became nationally qualified to compete at nationals. I have done a total of 5 competitions which has taught me a lot about presentation on stage, what the judges look for, and how to display your best look on stage. My passion and drive began 5 years ago when I met our head coach for Unchained Physiques Mr. Mike Rattenni to start learning and understanding the sport. I watched and observed Mike’s every move with his athletes because I wanted to learn and help people some day. That day has come! I help most of our current athletes now @unchained_physiques as one of the posing coaches but also inviting all beginners, NPC, and IFBB competitors that need or could use a posing coach. I can help you learn the basics of posing and what needs to be done for you to succeed on stage. I feel confident simply because of how much I practice and study the sport but more importantly how closely I work with IFBB PRO Coach Mike to keep improving and learning. Let's get your journey started!!!
