Issue #39: The (Em)Power Issue

For those looking to achieve their ideal shape, KGBody is here to help. The quickly growing fitness service, which has trainers in Los Angeles and New York City, was started by Katherine Greiner and aims to help clients establish a balanced, healthy, solution-based lifestyle through healthy dieting and consistent exercise.

KGBody: Where it all began

Katherine Greiner didn’t grow up with the dream of becoming a fitness expert. But following a set of unexpected events, she began to reevaluate her life. Greiner sustained a shoulder injury playing volleyball and needed surgery on her knee after a minor car accident. The healing process led her to reconsider the way she approached overall wellness.

“I had this moment where I was like ‘I know how to operate my cell phone better than I know how to operate or understand my own body.’ And that didn’t sit well with me,” Greiner said.

Around the same time, a close family member dealt with unexpected weight fluctuation as a result of an experimental treatment. Greiner credits both her personal injury history and the challenging experience of seeing a loved one deal with physical struggle as factors that ultimately led her to expand her understanding of holistic wellness. In addition to earning more than eight certifications, Greiner studied the Feingold diet (which calls for avoiding additives in processed food) and meditative techniques, to help her gain both mental and physical self-control.

Educating yourself on your body

It’s safe to say Greiner now knows more about her body than her phone. “My friends jokingly call me an education junkie,” she said. Training certifications are required to be updated, but this often goes unenforced within the fitness community. Greiner prides herself in maintaining her expertise as advancements are made in the world of health and wellness. “I feel like it’s my responsibility to stay educated and ahead of the curve,” she said.

Greiner suggests her abundance of certifications enhance her overall mindset when personalizing workouts for clients. “Not everything works for everybody; the core focus of what I do is helping people find their ideal lifestyle.” It’s all about finding what works best for the individual, Greiner says. “Everyone needs special consideration.”

KGBody’s Mission

KGBody does both group and individual workouts, as well as private in-home training. Greiner says she has worked with clients in hotel rooms, garages, on decks, and even over the phone. “Working one-on-one is my favorite part of what I do,” she said. “It’s really hard to not workout if you’ve got somebody who shows up at your door. It makes fitness more accessible to people when you show them how they can use a chair or a small dumbbell to get a full workout.”

Ultimately though, the goal of KGBody and its founder is to help clients establish and maintain a healthy lifestyle. Greiner has found success in her own life by balancing realistic expectations and disciplined habits. “For me the biggest key is practicing self-compassion. We all have days when we eat foods that are too salty or we’re too sick to work out that day,” she says. “Life is a journey, not a destination. All you can do is hope to do your best in the situation.”

So what’s the key to maintaining self-compassion in a practical way? Greiner says it’s not easy, but it calls for a long-term mindset. “Think about where you want to be five, ten, twenty years from now. Attainable goals are sustainable goals. What are things you can do that will keep you healthy and in shape and vibrant and alive 20 years from now?”
