Early Life

Leslie Kai Greene was born in Brooklyn, New York City.

Kai did not have a conventional childhood, being raised in foster care and residential treatment centers in Brooklyn. He had a lot of energy and was disruptive in school. Supposedly, because of his physical development, his teacher who was also a gym owner suggested he take up bodybuilding.

He talked about a time when his teacher put on the iconic movie Pumping Iron starring Arnold Schwarzenegger in class and Kai was instantly inspired. He says there was no more disruptive behavior after that experience.

So he started training as a teenager and knew without a doubt he wanted to pursue a career as a professional bodybuilder.

“I knew exactly what I wanted to do. I wanted to be a professional bodybuilder, I wanted to be Mr. Olympia.”

Competing in bodybuilding at a young age was a blessing because it brought him out into the public and out of the institutional facility. He started to love the sport more and more and was also very talented. It’s safe to say Kai Greene was meant for bodybuilding.

He learned a lot over the years that would follow and it made him a much better person overall.

Career and Competition

Kai Greene started training and competing as a teenager. He won several shows and determined that the sport of bodybuilding was something he was good at.

Greene has won major competitions including the New York Pro (2) and prestigious Arnold Classic three times to name his biggest victories. He also competed at the biggest and best bodybuilding show on Earth called the Olympia six times.

In 2011, he started working with George Farrah and the two made for a dangerous duo. Under Farrah’s guidance, Kai won the New York Pro that year.

In 2012, 2013, and 2014, Kai was the runner-up at the Mr. Olympia just second to none other than 7x Mr. Olympia Phil Heath. Many believe he should have won at least one of those Olympias. However, the judges didn’t feel he did enough to knock out the champ. The Predator was known to be vocal about his competitive frustrations.

He did not compete at the 2015 Olympia due to unknown reasons but he did compete in and win three more shows all in 2016 that included the Arnold Classic, Arnold Classic Australia and Arnold Classic Brazil.

Teasing A Comeback

Kai Greene Back

Since his last show in 2016, Kai Greene and his coach George Farrah have teased the possibility of the Predator’s return to the Olympia stage. However, when years continued to pass and it never actually happened, fans and the Olympia organization were upset that it seemed unlikely he wouldn’t be coming back.

Despite this being one of the biggest disappointments in the sport’s history, it’s hard to not appreciate the exciting and entertaining antics he brought to the sport. His rivalry with Phil Heath was one of the greatest ever and this is what fans missed.

But it was obvious Kai was more interested in pursuing an acting career and other business endeavors.

Kai had the following to say in an interview about the sacrifices to get to where he’s been. It takes a lot of discipline, focus and concentration to be elite at something and it was clear bodybuilding just wasn’t something he was sure he could devote all of his time to.

“I think one of the things that a lot of times we don’t realize, when we are working in just the capacity of being the athlete, we put so much time, and effort, and commitment into developing that focus that allows you to excel as the athlete.

A lot of times we don’t realize how valuable that power is, how valuable that thing, that human resource that we bring to the table, when investing in the pursuit of being the dominant athlete that you work hard to realize in that event.

I think that it is very real, to understand that with everything that you do, if you do it at a certain level of elite capability, there is a sacrifice. I’ve heard people talk about a sacrifice when I was the athlete, when I saw myself as just an athlete. I thought then that the sacrifice was only ‘Well I have to stay on my diet.’

I thought then, that the only sacrifice was ‘Well I have to eat in this very restricted, and measured way.’ I realize now, on this side of it that no, that’s not the sacrifice. That’s not a sacrifice, that’s what you have to do in order to get to the level of achievement that you’re working for.

I now understand that the sacrifice that I thought I understood then, is the time and the use of your effort and focus. Your time and concentration. That is a very very valuable virtue.”
