GenX Fitness

I hate the gym, but I know it’s good for you. Training with Gen makes it fun He is so knowledgeable he can help me get strong enough to do the monkey bars with my grandson (something I never could do back then) or heal from an injury I look forward to my weekly workout it’s fun and keeps me fit and young

I love Gen's patience and expertise as a trainer. He helps me keep focused and improving and his personal story is inspiring.

Gen B. is a great trainer. He tailored a number of workouts to meet my needs as a client. In addition, he is a great communicator when he talks about the technical part of working out.

I have been training with coach Gen for over 2 years now, and have made significant strides in my fitness level. I'm so much stronger at age 67 than I was 2 years ago. Gen is highly skilled as a personal trainer, instilling confidence and trust in his clients, while still challenging them to the max. If you work with Gen you get the best of the best, as well as his great personality and sense of humor. I've trained with other trainers before, and can wholeheartedly recommend Gen if you're looking for a great trainer. More...

Very knowledgeable and tuned in to what I need in any given day. Lots of options. Pushes me to do my best while being careful to avoid injuries

I love working out with Gen. He is very upbeat, knowledgeable and keeps the workout lively. He has helped me gain a fitness level that I can keep up and my weight has dropped as well. We do boxing at the end of each workout which is ridiculously cardio intensive. Gen keeps me focused and motivated and I keep coming back for more! Highly recommended. Gen is also a genuinely nice person and funny. Great combo More...

Without a doubt, the best money I have ever spent. I found Jenn here on Yelp about a year ago. I had no idea what I was getting myself into, but joining Aguirre Fitness changed my life. I've never been comfortable in gym settings, but Aguirre Fitness is different. There is a real sense of community, and I adore everyone I've met there. Some of the nicest, down-to-earth and authentic people I've ever met. During the morning session there is a spread in age from 23 to almost 80, and it's usually the younger ones trying to keep up (myself included). It's very inspiring to see what is possible at any age. Jenn is tough, but also very supportive and encouraging. If she takes you on as a client, you will never doubt that she is in your corner, has your bests interests at heart and is invested in your success. She cares for each and every one of her clients and it shows. She pushes herself harder than any of us. Although she has been a trainer for almost 20 years, she is always taking a class, attending a seminar, or coming up with some new torturous exercise, because good enough is not good enough for her. She is striving to be the best version of herself, and that is the level of dedication that she brings to her clients. If you are ready to commit to change, there is no better place than Aguirre Fitness. More...

I've been a fan since the very beginning in 2010. But you will never hear me say it's easy. I feel very fortunate to be able to work my schedule around my morning workouts with Jenn and/or yoga with Francisco (Hercules Yoga - conveniently located upstairs at Aguirre Fitness). Jenn is serious about fitness, always on time and always accessible for questions. If you're serious about fitness, weight loss, strength and want to be surrounded by like-minded individuals then this is the place for you... no matter where you start. In 2010, I lost over 100 lbs by cleaning up my eating (not by starving), doing regular cardio, and regular workouts with Jenn. No quick fixes people but definitely hard work and results!! Hercules Yoga led by Francisco Flores has enabled me to not only find and develop inner peace but over time has become a perfect coupling with my workouts. I have a noticeably better range of motion, less soreness after workouts, and increase balance and flexibility. I look forward to my yoga. Fit Flow and Back care are my favorite sessions but I occasionally have enough bandwith for BOSU and Pilates. Love it all! More...

3 years ago, I began training here after seeing one of my dearest friends who I hadn't seen in a long time and her body was jaw dropping! I joined Aguirre Fitness and within THREE months of working with Owner Jenn, following her meal education & getting my cardio in...soon I was in THE best shape of MY life!! NOW~ after a painful back injury, a life-altering professional change and THE most insane hours you could imagine... I'm trying to get my life back to normal. Jenn works with me and designs workouts JUST for me. She watches like a momma bird too ensuring that the exercises are being done correctly. This place is my home. Sure...I could go someplace closer to home or even cheaper...BUT....I won't. # LOYALTY #QUALITY. The transformations that happen at Aguirre are not only physical, they are mental and spiritual...balance both inside and out. I know the quality, experience and expertise of my coach and I wouldn't change not one crazy, exciting, challenging thing about it or her! Try it for yourself! More...

Erica at Aguirre Fitness is no joke. She will transform not only your body but your mind. Over a 6 month to a year time I watched my sister evolve into a body and mindset I didn't recognize. She trains your muscles, your eating habits, your bad habits, your energy level to an extreme. Erica literally changed my sister's life. I am still looking for someone like her in my new town. Thanks Erica for changing her life! More...

This training studio provides so much more than the traditional weight lifting and cardio. There is a plan set in motion when you sign up with one of the trainers. I was very hesistant signing up at first, but what did I have to lose but some pounds and gain so much more in muscle, knowledge and a great group of folks to workout with. My health and well being are definitely an investment to myself.The owners Jenn and Christian are fantastic. Each client has their own individual goal therefore the workouts are customized to what you are seeking to reach. The workouts are beyond challenging and quite innovative along with some traditional basic moves. Nonetheless you will sweat and burn some major calories when you put that work in (and believe me all the clients here do as we push through the pain and provide support) Also, results come from good nutrition and all of this is provided along with holding accountability through food logs. You will not be short changed here. It is definitely worth the time and investment to get into the best shape of your life. I found it here and it has changed me inside and out to also help me in my aerial game. (For those who know) This is one of my many fitness families I definitely recommend. You can also follow the Aguirre duo on their YouTube channel for tips, motivation and workouts. Get moving and get working! More...

I started with Aguirre Fitness and Christian Aguirre as my trainer just over 2 years ago. I will not be admitting my weight but in just over a years time with him I lost over 100lbs. Christian is so supportive and motivating. He can work around injuries and although he is always challenging you he is never pushing for anything you can't do. I had many moments of thinking "I can't do that" but then lo and behold, I did it. I cannot recommend Aguirre Fitness enough. All the trainers are great, I always worked with Christian so am just a little biased there. I had to leave Aguirre Fitness just recently when I got pregnant because my doctor made me. I miss it so much and look forward to getting back to it after the baby is born. Plus I will have all the pregnancy weight to get off and now at least I know I can do it! More...

The best thing I did for myself was to join Aguirre Fitness!!!!
I’m super busy all the time; always do everything for everybody else. However it was really hard to find time for myself. Now I wake up at 4 AM everyday, and the first person I take care of is me. I have been working out for five weeks now. Don’t want to ever stop. Since I started I lost 9 lbs and 15% body fat. I have a lot more energy now. Maggie
Christian is the toughest-sweetest guy that I’ve ever met!!!! He really helps and pushes me to succeed. When I have questions he responds to my emails right away.
I was working out for only 3 weeks and was able to wear a dress that was stuck in my closet for such a long time. Before working out I would not dare to even try on that dress.
Definitely joining Aguirre Fitness was the best thing I’ve done for myself. If I were you, I would do the same. More...
