For such an influential person as Kim Kardashianthere is hardly any downtime between hacking the internet and running multiple businesses. But even with a non-stop schedule, she makes time to work on her killer body. Kardashian doesn’t compromise when it comes to her workout routine, and according to her trainer Greca agreesMBA, founder of WeRise and NikeSkims athlete, it is precisely this commitment that drives his results.
“My philosophy is simple: build strength that lasts,” she tells SELF. “Aesthetics are a by-product. The real goal is that longevity, flexibility, and the confidence that comes from strength training.” It’s a mindset he’s developed over years of training—having cycled through high-volume cardio and endurance training himself. “Nothing has given me the confidence, flexibility and self-belief that strength training has,” she says.
He applies the same philosophy as a celebrity trainer. “I work with high-profile clients like Kim, and the method doesn’t really change,” says Greca. The bottom line: to help clients see their body as something worth investing in for the long term. Greca believes that your body is your home – so it should be treated with respect and care.
He adds that strength training is not only about getting stronger in the moment, but also about protecting your future health. It plays a key role in preventing conditions such as bone density loss and muscle loss while supporting everything from metabolic health to cardiovascular fitness. “I want to live in this home as best I can,” says Greca. “So that we can still do what we enjoy on the road.”
His method starts simply: learn how to move well, then gradually increase the load. “About moves with vigilanceyou learn proper form and breathing patterns and then gradually get stronger in a safe way,” he says. But that doesn’t mean the workouts should be rigid-or boring. In fact, Greca intentionally builds variety and enjoyment for Kardashian. “You have to be playful,” he says. “We built the mindset that training is what we do there is to do something instead of what we get to do.”
The balance of structure and flexibility is especially key when training someone like Kardashian. “He’s very busy, but he makes training important. It’s in his schedule. He shows up. There’s no negotiation,” says Greca.
So what does this actually look like in practice? For Kardashian, workouts are usually split lower body strength days—focusing on the legs and glutes—and upper body and seed sessions, occasionally with a full-body circuit.
