“Organizations rise and fall on leadership…I thrive on investing my time, resources, and knowledge to create the perfect place for you to become a healthier, fitter version of yourself.”

Owner and coach, Mike Petruso, prides himself on creating a fitness community and culture where every athlete, regardless of fitness level, is treated fairly. He is extremely passionate about helping you reach your goals, surpass them, and literally become the best version of yourself possible.

He is a CrossFit Level 1 Trainer and has a CrossFit Weightlifting Certification and a CrossFit Gymnastics Certification. Mike is currently pursuing his Level 2 training status and always working on more to fulfill his hunger for knowledge.

During a CrossFit workout, you are constantly working your muscles (and brain) in new ways to give you a better physique while keeping your mind and body from simply going through the motions. CrossFit Wildwood has seven classes a day that are all a little different and fun – they’re fast-paced and motivational, leading to dramatic fitness gains. You’ll see noticeable changes quickly while eliminating hours spent at the gym! Whether you take one of Mike’s classes or choose one-on-one coaching, he will bring out the best in you if you are willing to show up, listen and take action.
