Hardcore Fitness has completely changed my life and the way I look at working out. This is the first time I’ve ever stayed consistent with any fitness routine, and that says a lot! Since joining, I’ve lost weight, gained muscle, and feel stronger and healthier than ever before. I actually look forward to pushing myself in ways I never thought possible.
I used to think strength training was just for men or bodybuilders, but I quickly learned that’s so far from the truth. There are so many strong, inspiring women here, and I’ve seen firsthand how great strength training is for your overall health—especially your heart and muscles.
The trainers at Hardcore Fitness are truly amazing. They’re incredibly supportive, knowledgeable, and always there to help you through every workout. They genuinely care about you—not just your results, but how you’re feeling physically and mentally. They make sure you feel comfortable, confident, and capable, no matter your fitness level. They’ll even adjust exercises on the spot if you’re dealing with any back or knee issues.
And the community? It’s the best part. Everyone is so welcoming and encouraging, and I’ve made so many great friends along the way. Hardcore Fitness isn’t just a gym—it’s a family that helps you become the best version of yourself!

Been a member of Hardcore Simi Valley since it’s opened and it’s been the most beneficial experience in my health journey. Trainers are well informed focusing on posture, safety and to help each member get stronger through strength training. I have never felt this physically and mentally strong and I give all my credit to Hardcore. Highly recommend!

Hardcore Fitness - Simi Valley is a game changer!

I can't say enough good things about this place. From the moment I walked in, I felt welcomed, motivated, and pumped to reach my fitness goals. The energy in the room is contagious — from the music to the trainers to the other members, everyone is there to push themselves and each other. It’s not just a gym; it’s a full-on community of support and drive.

The workouts are dynamic, challenging, and never boring. Whether it’s strength training, cardio, or a mix of both, each class keeps you moving and engaged. You leave sweaty, sore (in the best way), and already looking forward to coming back.

But the real magic? The trainers. They are next-level amazing. They’re knowledgeable, encouraging, and genuinely invested in your progress. They take the time to correct form, offer modifications, and keep you fired up throughout the entire workout. You can tell they love what they do — and it shows.

Hardcore Fitness has completely transformed the way I approach fitness. The culture here is unmatched — positive, inclusive, and motivating. I’m stronger, more confident, and more consistent than I’ve ever been, and it’s 100% because of this place.

If you're looking for a gym that will push you, support you, and make you feel like part of something bigger, Hardcore Fitness Simi Valley is where it’s at. 💪🔥

This place is amazing! I am known as your typical “gym hopper” because once I get bored of a place or it doesn’t challenge me anymore I’m done. I cannot say that I am bored of this place. Everyday is something new or I push myself harder, higher reps or higher weights. The staff is great and the owner Alisha is fantastic. 10/10 recommended

Hardcore is such an awesome gym, the trainers are awesome, the workouts are killer in the best way, and the gym is spotless! Also super aesthetic which is so cool. I love how the trainers have a lot of knowledge and have alternatives to workouts depending on where you’re at in your fitness journey, injuries, etc. if you have the pleasure of meeting and talking to Alisha the owner, she is amazing. She makes you feel welcomed and comfortable and genuinely cares for her members. The members also are so great. Everyone welcomes new people with open arms and it’s an amazing community. I highly recommend this gym to anyone who is nervous to start their fitness journey, you will feel loved and motivated as soon as you step foot in the door!
