Fitness History
Quantum Performance Training’s Founder Marc Siegel started his quest to change his body and create a company at once! Roughly ten years ago Marc was 250 lbs, 42 waist, and 44% body fat. After deciding it was time for a drastic change, Marc left banking in NY, and moved to FL to learn his craft and start a new journey. Fast forward about a year, Marc is now 192 lbs, 34 waist, 7.3% body fat, and a licensed Personal Trainer. After years of training in Florida Marc, his wife and new baby decided to move back to NY to be with family. Marc immediately hit the ground running in New York Sports Club. Starting at the bottom as a floor trainer, moving to Fitness Manager, Dual Club Manager, then Area Manager. Marc at his peak was managing over 24 trainers and hundreds of thousands of monthly training revenue. But like anything else to much of anything isn’t always the best thing for you. In August 2016 Marc and his family decided to once again to live the Florida lifestyle. After exploring Jupiter and its surrounding area, Marc decided that the best thing for his family, himself, and his new perspective clients would be to “re engage” Quantum. Here we are less then a year later, and are looking forward to big things in 2018! We are always looking to grow by helping people better themselves. We look forward to working with you!

Marc runs the best small group class I have ever been a part of. His training knowledge knows no bounds, which makes each class unique and fun. He is always encouraging and inspiring. I have lost almost 10 lbs and 6% body fat, and I continue to feel stronger! Thanks Marc!

My workouts with Marc have been nothing short of sweat & fun! Marc is very knowledgeable about all aspects of TRX and various other training styles. We as a class have developed a client-trainer relationship with him that individualizes each of us to our level of capability. Marc pushes us further each time we meet and I feel stronger each week. Marc has a fun disposition and I luck forward to every class. Being in my 50’s my metabolism has slowed down a bit, however in the past 3 months I have lost over 5% body fat, and put on a few pounds of lean muscle 🙂 Thanks Marc!
