To say that Ivan Lopez is an amazing trainer, would be an understatement. Ivan has been training me for a little over a year now and all other trainers I have worked with pale in comparison to him. His workouts push the limitations of my physical abilities without compromising muscle flexibility or muscle injury. He constantly encourages me to push myself in every workout and never slack, no matter what. As a result, I increase in strength, flexibility, endurance, and confidence with every workout. He is very knowledgeable in every aspect of physical fitness. From eating healthy and consciously to working out with confidence, he knows what you need to be and feel your best. I am currently a Division I water polo player at Loyola Marymount University and I can happily say that Ivan Lopez has helped me achieve the physical ability and workout attitude to reach this level of athletic competitiveness. Ivan Lopez is a great and versatile trainer but, most importantly, he is a friend. I guarantee that if you train with Ivan Lopez, you will not only become stronger, faster, more conditioned, and confident, but you will also gain a great friend in the process.

Great gym, very personalized training and brand new equipment. Ivan has been wonderful and the staff there is very friendly. UPF is much better than the overcrowded gyms I have been to. If you want a great workout and one on one training I highly recommend Ultimate Performance & Fitness.Update: I’ve been MMA Training with Ivan for the past three years! It has been an awesome experience and his knowledge of this sport is amazing. He has trained lots of professional fighters and athletes and you can’t find a more insightful coach either. Any fighters that want to hone their game, especially standup, would be lucky to train at UPF.

This place is amazing. My trainer really focuses on my individual needs and is one of the best around! The gym is kept very clean and has all the right equipment for a great work out. UPF is better than a traditional gym since you don’t have all of the crowds. The best gym experience!


Ultimate Performance and Fitness is the most incredible and innovative gym around. The equipment and facilities are new and kept very clean. The staff is all very friendly. In addition, you receive a thorough and intense workout because you are not waiting for machines and equipment like you would when working out a “corporate chain” gym. I highly recommend if you want to get fit and in shape you check them out and give Ultimate Performance and Fitness a try today!


Ok, how great is it to exercise with a trainer and without the noise and crowd around getting in the way!! My workouts are demanding but without the hassle of the crowd at the club. The facility is awesome and I can’t say enough positives on the friendly and qualified people at Ultimate Performance and Fitness.


This place is fantastic, all the trainers are outstanding-and Ivan, well to put it simply, has changed my life…I highly recommend this new clean professional facility! What a welcome change from the over-crowded, over-used, dirty meat markets I’d been training in before! Thank you UPF!! 🙂

Ultimate Performance and Fitness Gym in Westlake Village, CA is the best training facility I have been to. The trainers there are great and they really push you to exercise hard and get the best possible results.

UPF and their staff have been very instrumental in my life in and out of the gym. After going through three bouts of leg surgeries, I’ve always been able to depend on Ivan and his team to get me back on the road to my best recovery.
The most rewarding aspect of UPF is that they provide one-on-one training that is so hard to find at other fitness centers. Speaking as an athlete myself, other fitness centers can give off the impression that you are merely just another one of their members. Here at UPF, they make you feel like a part of the family.
Not only do you get superb training and workouts, you also get the benefit of building lasting relationships with Ivan and his staff. UPF is the new age in fitness, trust me.

If you are looking for a great trainer you have come to the right place. This gym is amazing and everyone is really friendly. I followed my trainer from another gym. I feel our workouts are distraction free and there’s no waiting for equipment. You truly get one-on-one attention!


Ivan is the best trainer in the area and the gym is so clean and well laid out. No crowds…just a great workout with the best staff.


It’s wonderful. I have more time with my trainer because there is no waiting to use any of the equipment (no crowds). Everything is new and clean. No problems finding a parking space. All the staff is very friendly every time I come in. I actually enjoy coming to the gym now.


I love working out at this new gym. Ivan and his trainers are knowledgeable and supportive. Your workout is individualized for your own needs, which means you will see results sooner. The brand new equipment and clean surroundings really make this the ultimate place for fitness in Westlake!


UPF is in a personal training studio league of its own! They made me feel like I was getting all of my money’s worth through their personalized service and knowledgeable trainers. From the time I walked in the door I knew that this was not your typical gym. The trainers are experienced and professional. The equipment is all new and the facility is super clean. It’s a great place to workout and I love that I don’t have to pay membership dues.


Ultimate Fitness and Performance has proven to be a perfect place to get in shape and work with a private trainer. They tailor the workout to fit your goals and body type. They are great at motivating you to keep in shape. All equipment is new and state of the art. I have worked out for years and this is the first time I actually feel motivated to go. I highly recommend their private training sessions – they are well worth it!
