About us

What is Hardcore Fitness?

Hardcore fitness is more than just a gym.

We are a supportive and motivating community that welcomes all new members with open arms. Whether you are an athlete looking to step up your game or someone who has never stepped foot in the gym, you’ll feel at home and be pushed to your personal best in each class. The energy of the classes paired with the top-of- the-line sound system and motivation and experience of the trainer on the mic make for a workout experience like no other. We’ve got your back with a solution for your weight training, cardio, core,nutrition, motivation and even accountability!

The Community

We hear all the time that people heard about how amazing Hardcore Fitness was and had seen the amazing results, but were too intimidated or afraid to take the leap and give it a try. After their first time in the gym, that went out the window and they wished they’d come in sooner!

From the time you walk into the gym and talk to staff and members to your first class with the trainers and the people working out around you, you quickly see that this is a true fit weight loss challenge family and we are all about encouragement. The people you’d normally be intimidated by because they were in great shape are the first ones to offer help and give you encouragement or motivation through the workouts. It becomes so contagious that before you know it that person encouraging others will be you!

This is what makes HCF so great!

The Founders

Hardcore Fitness was founded in 2007 by Larry and Nadia Nolan. The program started as an outdoor boot camp led by Larry, and his only two clients were his girlfriend, Nadia, and his mother, Vicky. Larry had been a trainer since he was 16 years old, being certified by pretty much every institution and working at every corporate gym. After years of seeing gyms’ sole focus being profits, with no concern for clients’ wellbeing or results, he decided to go off on his own and build the gym that he saw in his mind’s eye. The new gym focused on every aspect of the clients’ experience, from the atmosphere and culture, to accountability and results.
Nadia started off as Larry’s client, but her passion for training and the Hardcore Fitness clients quickly grew and drove her to quit her finance job and devote herself fulltime to HCF.
With the two of them working side by side and focusing entirely on the clients first and foremost, they had great results and happy clients to show for it. Neither Larry nor Nadia were very business savvy, so there was never a surge of clients or major expansion; rather, the program grew one client at a time as people would see their friend, neighbor, or family member’s amazing results and hear them raving about their great experience at HCF, and come to check it out themselves. After years of being in the park, the program finally grew to a small 1,800 sq ft indoor facility, which it quickly outgrew into its current 11,000 sq ft facility. Since 2007, Hardcore Fitness has been voted best gym, best boot camp, best personal trainers, even one of the top gyms in the US, and expanded to locations from Santa Clarita, California to Orlando, Florida. Despite this growth, the gyms’ main focus remains the clients. Each gym that has opened has been in partnership with one of our trainers, clients, or staff members that has fallen in love with the Hardcore way and promised to bring the same love and attention to the new location that Larry and Nadia brought to the original. With this approach, you can always be assured to walk into any Hardcore Fitness and feel welcome, get a great workout, and have the support you’re looking for in all ways! Along the way, Larry and Nadia also competed in fitness, turned professional, competed for a world title, started a supplement line, got married, and have two chogs (dog children), but at the end of the day you’ll still see them daily at the original Santa Clarita location doing what they love with a lot of the same clients who began this journey with them back at the park.
