Nick Singer

CEO & Founder

American Council on Exercise Certified Personal Trainer

Specialties: Fat Loss, High Intensity Interval Training, Body Building, Strength Training, Power lifting, Injury rehabilitation, Nutrition

Nick is a CPA, an entrepreneur, a power lifter, a wrestler, but most of all, a health enthusiast. Nick has vast experience in training people all over the spectrum including kids, seniors, athletes, bodybuilders, people with injuries, and people who just want to lose weight or gain muscle. Nick has written hundreds of meal plans to help people reach their fitness goals. "I started learning about nutrition when I was wrestling because I had to lose weight and wanted to do so in a healthy manner," he says. Whether Nick is eating 5000 calories a day or preparing for his power lifting competitions, he is always trying to become the strongest version of himself. "You see, I'm not satisfied with just being strong. I want to be the strongest version of myself possible and to do that I need to be strong not just physically, but physiologically and energetically and then I need to share that strength by showing others how to do what I've done. Then, and only then can I consider myself the strongest version of me."

 

Karl Lataillade

Director of Operations

National Academy of Sports Medicine Certified Personal Trainer

Dotfit Nutritional Certified

Annette Lang Integrated Stretching Certified

Specialties: Weight loss, Toning, Athletic Training, Boxing Target Mitts, and Muscle Hypertrophy.

Karl grew up in Bethesda, MD. When he finished school here in Maryland, he moved to New York City. After six years in the Big Apple, Karl decided to return to the DC area and bring this knowledge and experience back home with him. Working as a Personal Trainer on Wall St., he understands and respects peoples busy schedules and hectic jobs. That is why his philosophy when he was a trainer is to make training as fun as possible, while eliminating the word can't from your vocabulary. As the Director of Operations of Fitology, Karl brings that same philosophy in trying to make Fitology a relaxed stress free environment where people can enjoy themselves while getting in shape. "As a Personal Trainer, my goal was to make exercising as fun as possible for the client. My two favorite things about training is when clients push themselves to limits that they didn't know they were capable of, and also when they get the results that they want, look and feel good about themselves and all the work they put in. I like to think of our sessions as a place to get away from it all, a place to have a good time, a place to laugh while breaking a sweat, and targeting the body parts you desire to improve on."
