Not bad, kind of a small gym with limited variations in equipment, but still gets the job done. Just expect to wait for someone to finish using the machine that you've been waiting forever to use because they're stuck on their phone. Actually, just ask them if you can hop in or how many sets they have left.

Lots of equipment!!

I look forward to going to the gym. Cameron, Trevor, and Shy are awesome. They are welcoming, and willing to help. GREAT PLACE

I have been working out for the last 45 years on a consistent basis, I have done weight training in my earlier years and thought that I knew pretty much the technique and what I was doing many years have past and my exercise routine has changed now that i am 65 years of age. now that I am older, I need to be more mindful of my use of weights and thought it would be proactive of me to hire a personal trainer. Through fitness 19 I was introduced to Trevor Lytle.. I was so impressed with his technique information and knowledge on what works best for me his teaching technique is so easy to follow that I am able to do on my own learning the machines and free weights I am so grateful for his Professional service Thank you so much Trevor

Here's the one next to me.  I cleaned off mine after use, and the towel was black.

I had to leave this gym. Just too dirty and they seem to have a lot of plumbing issues. No professional cleaning ever. Too many kids in pajama bottoms and flip flops hanging out on their phones.

I've been training with Jerome at Train Goat Gainz for well over a year now and I can honestly say…read morethat he completely changed my body! I went into it feeling pretty fit but wanting to work on some specific "problem areas" as well as gain endurance, strength, etc. I've worked out at multiple gyms and with all different trainers. Problem was, those cookie cutter workouts were not working for me and made me very discouraged. Jerome listened to my concerns and what I was hoping to gain and boy did he deliver. I can say without question that Jerome got me into the best shape of my life!! I got cut, lean, strong and most of all pushed to challenge myself in a way that makes me feel like a strong woman! He now also trains my daughter who is 12, yes 12. Middle School, worst period of any young girls life. She boxes and trains with him twice a week and he has helped turn her into a fierce young gal who only gets up early (willingly) for three things 1. Jerome 2. Disneyland 3. Surfing. If you decide to do one thing to start out 2021 the right way, book a session at Train Goat Gainz!!!!

First: my son trains with Nick and Jalen for football. They worked with him for a few months before football season started back up again and wow what a difference. His football coaches noticed a SIGNIFICANT improvement in his performance on the field to the point where they were asking, "what have you been doing off season?!". When setting up our first training sessions we asked for personalized training for specific positions and they delivered! Get ready to put in HARD but rewarding work! Second: My son and daughter both worked with Shelya to improve their speed, strength, fast twitch muscle movement, and endurance. These sessions had them gaining muscle and speed like crazy! All 3 coaches have been a pleasure to work with, they are kind, caring and will push your kiddo to be great! A side note: if you do not hear back from Coach Dru right away...keep trying! Worth the wait to get a spot on the training schedule!

She…read morecreates meal plans, workout regimes, and intentional recovery days that thoughtfully and safely help you toward your goals. She provides a wealth of knowledge on how your body works and why you are doing what you are doing, along with supplement suggestions that never feel pushy - just tools you can choose for your toolbox if you'd like. When the going gets tough, she has an abundance of tips to make diet and workouts more palatable and is always there as a friend to commiserate and build you up. Jen leads by example at Hardcore Fitness, and has built the most caring and supportive fitness environment I have ever experienced - from the trainers through the members. This is her family business and she makes all of her members and clients feel loved like family. I recently completed a 60- day fitness challenge at Hardcore, run by Jen. I gained strength and confidence, while losing inches off my body. My favorite part of the 60 day challenge was the supportive community of other participants. People their stories, struggles, wins, tips, and support for each other both online in our group video discussions, as well as as in person at the gym. The community really keeps you engaged and focused on your goals. This experience has given me better knowledge of what my bad habits weee doing to my body and what good habits I could foster for benefits I want. I plan to keep these learnings top of mind as I head into my (new and improved) regular routine. I recommend Hardcore, Jen, and the trainers highly to anyone looking for a gym family/home. You can generally find me in a Lift class or in the Red Zone Rumble boxing class six days a week. I can't get enough of it!

Coach Mario is also the bombbb (used to have him as a trainer at another gym) & he has the best energy! Also, if you are injured they have modifications so it's Just great!

There are several people he is down right degrading to in an open public forum. This does not promote "well being" . My journey there ended when we had a difference in opinion and he basically pushed me into quitting while taking his hand out for the $250.00 buy out fee to cancel my contract. When I sent him a message he didn't even respond. as much as it saddened me to leave the network of support there it was the best mental decision I made. Saddest part is when ex Hyperion people do negative reviews they won't post their names like me due to the fact of the harassment they would get from Mr Selvian. I continue to get calls from people who tell me because they "liked a post of mine" Eric will call or text them and inquire why their friends with me. Eric get a clue. The people of Hyperion are not "your property" comments made to my friends such as "I'm glad Tina didn't make he weight loss goal" are not only unprofessional but so immature it's embarrassing!

I've been doing Orangetheory on and off for about 10 years (started at the Northridge studio), and since moving out to the area I've been coming to this location more consistently the past few years -- and I genuinely can't recommend this studio enough. Every coach I've taken here has been great, but shoutout to Koda and Julia -- they're amazing. They're not the type to just stand at the mic and call out times -- they're constantly circulating on the weight floor, helping with form, giving adjustments, and making sure you're doing movements safely and effectively. I also really appreciate that if you stop for a second (we've all been there ), they'll check in and encourage you without making it uncomfortable. It feels supportive, not pushy -- and it helps you keep going. I've also dealt with a knee injury in the past, and I really appreciate how willing the coaches are to offer options and modifications. After my knee injury and surgery, I actually started on the bike and gradually worked my way back up to the treadmill once my doctor gave me the green light. I also love that they offer the elliptical as another option -- it makes the workouts feel really adaptable no matter where you're starting from. A lot of people mention the weights may not feel "heavy enough" if you're someone who wants to lift super heavy, but for me it's more than enough. The workout is so well programmed that I still feel challenged every time. The front desk staff deserves a shoutout too -- they are SO warm and welcoming, and they're flexible and lenient when life happens and you need help with anything. It's one of those studios where people actually learn your name the more you come, and you start recognizing the same faces in class -- it ends up feeling like a little community. Logistics and amenities are also a big plus: Easy parking, super clean studio, well-maintained equipment, two single-use bathrooms, two showers (huge if you're heading to work after), and two filtered water stations. Ambience is also just... chef's kiss. Working out under the orange lights at 5:15am hits different -- it's a whole vibe. Yes, Orangetheory is an investment, but for me the unlimited membership is worth it because the more consistently I go, the more I see and feel a real transformation. I'm doing the Transformation Challenge right now (and part of it is posting a Yelp review), but I'd be saying all of this regardless -- I recommend Orangetheory Westlake Village to anyone who asks what I'm doing for workouts. If you're on the fence, just try a class. It might surprise you in the best way.

I've been training with Dan for almost six years and trained with his wife, Sami, for about a year…read morebefore that. Simply put, they deliver results. As a lifelong runner and yogi, I was honestly intimidated by heavy weights at first. I started working with Dan and Sami to build strength before trying to get pregnant... and not only did I reach that goal, I believe that strength training made a huge difference in both of my deliveries. They guided me through recovery after each pregnancy, helping me lose over 90 pounds after my first and 40 after my second, all while gaining muscle and confidence. Now, approaching 40, I'm in the best shape of my life: physically strong, mentally energetic, and genuinely excited about my workouts. Dan has also helped me cross-train for 3 half marathons in the last 18 months with zero injuries. Both Dan and Sami bring such a positive mindset to every session that training feels like something to look forward to, not a chore. They've taught me skills I can apply on my own and helped me understand how nutrition supports performance. Dan's guidance on macros and his honest, thoughtful feedback have been game-changers. I can't recommend Nano Gym more highly. They've transformed not just my body, but how I feel about fitness and strength.
