Martin is an exceptionally knowledgably professional. I came to him broken and demoralized. A former college athlete who continues to train, I have seen my share of PTs, Trainers, Doctors over the last 30 years. There is not one professional who has provided more growth and hope than Martin. I won't trust my body to anyone else. I recently had two cervical fusions and had deteriorated over the course of year. Add that to a decade of poor movement patterns and increasing instability. II felt I was never coming back. Martin has started me at ground zero (which is what I needed) working my neurological systems before progressing to actual movement. I can guarantee you there is not anyone in San Diego who knows more about assessing and building the human body holistically than Martin. I won't do anything at this point in my recovery before clearing it with him. I don't even bother to call my Drs. If you want to heal, grow and become a stronger person., call Martin. read more

I had a great experience working with Martín from Perform Center. He pays close attention to you while you are working together and is focused on long term health and gains with tour body. He is a wealth of knowledge and knows how to push you safely. read more

Martin Alonzo of Performance Training Center has been my trainer for about 4 months, and I'm very happy with the results. I had been through a difficult recovery from surgery to correct a hip and thigh injury. After 6 months of a very slow recovery, I'd started to believe that at 58 my body just wasn't going to recover enough that I'd be able to go back to the hiking and walking that I'd enjoyed before. After my course of treatments, my physical therapist suggested that I call Martin to further my recovery. I must admit that I was quite intimidated to show up at Martin's studio. He is very strong and the picture of health. I thought he wouldn't be able to relate to me. And I also worried that I'd experience more pain from the work out. But I gave him a chance, and I'm so happy that I did! He has a very good understanding of how the body works and he was able to identify the reasons for my discomfort and to correct the problem. He was also incredibly kind and patient with me. Martin has been able to restore my gait to normal and to show me how to keep from experiencing back and hip pain. It has been a joy to resume walking and hiking with my friends. I've also begun a swimming program! I am grateful to have another chance to experience an active lifestyle. I can't thank Martin enough for all he has done for me. read more

Martin has been a true professional in every sense of the word and I am grateful to have connected with him.

Martin Alonzo developed a very strategic plan to help me strengthen shoulders, back, and core along with increased flexibility. All of which help with swimming, golf and daily activities. No more lower back pain and stiffness as long as I continue the stretching and exercises he taught me. You could be next!! read more

I met Martin through a few coworkers. He has worked with them and their results are AMAZING! I set my mom up with Martin because she was struggling with finding the correct workout for herself. I did the initial consultation with her so I could learn what she needed to do to keep her accountable. Martin is wonderful and professional! He reviewed her current workout plan as well as nutrition. He educated her on how the body worked and changed with different workouts. He also took her body measurements and examined her basic workout positions to see how he could help. She is only coming into her 3rd week with him and I am noticing progress from her mostly with mindset. She is a STUBBORN woman who does not listen to anyone when it comes to changing her workout. Martin is incredibly patient with her and walks her through everything and keeps her in check. I am so excited to see her progress at the end of it all! read more

I'm not the kind of guy that expected to have a personal trainer.... but I can't imagine life without my weekly sessions now. I've been a client for a few months now. As a trainer, Martin has the encyclopedic knowledge of strength training, nutrition, mobility. Honestly, he knows it all. He will coach you on how to get (and keep!) that healthy lifestyle. He's a guy that loves his craft and is always looking to improve. He is always researching/learning new techniques and methods, which keeps the sessions fresh and fun. As a person, Martin is a seriously good guy who's got your back and truly enjoys helping you achieve their fitness (and life) goals. He's not your typical trainer, he has depth and leads a fascinating life both outside and inside the gym. He's a pleasure to be around and learn from. He is very kind and classy. Very professional. I have recommended him to my wife and sister. In terms of results I've personally experienced, in my few months of training with Martin, I have lost 10lbs and got so much strength in my core and back. Every session is full of different and new workouts and fresh information about body and food. read more

Clients be aware of hidden cost with paying Martin Alonzo for packaged sessions. I paid for 10 sessions but after 2 sessions I decided it was not a good fit. He took almost 2 months of repeated emails to refund my money and then held back funds for his research time.... I was correct in my feelings of his moral compass. read more

Being training with Martin for over six months and in that period of time I have learn so much from nutrition to an extend of many works out I never thought I could ever do, Ive never being able to lean out because of my lack of knowledge in my nutrition n exercises until I came along with Martin. He's committed n you can see the passion to see u get the results u look for, he will push you to the max during his session but when you leave you have to continue to push yourself when his not around to see results fast. Very grateful n look forward to my sessions every week thx again read more

The best Personal trainer in San Diego very knowledgeable of you needs and Fitnees I really recommend ++++++++

Martin is an incredible trainer. His knowledge of physiology and anatomy is amazing. He has a professional and easy demeanor which inspires me through my workouts. I'm 69 years old and feel like a new man due to his ability to help me re build my strength without fear of injury. read more

When I started to train with Martin I was recovering from a shoulder injury. I was participating in a HIIT program but I felt my strength training was less than optimal. I have flat feet, knees that cause challenges, etc. I needed someone that was familiar with those issues and could teach me good form and help me improve my strength without injury. What I particularly liked about Martin was that he looked at me as a whole as opposed to giving me some exercises and counting the sets and reps. Martin took a look at what I ate, my digestion, and how I slept. I consider him my partner in health. I highly recommend Martina and Performance Training Center. read more

Throughly enjoyed working out with Martin! He is super friendly, approachable and upbeat. His workouts were always challenging and varied so you won't get bored while you're getting stronger with every workout. I trained with him for about 3 months on a weekly basis. I only stopped because I'm now on a budget. I also did the nutrition component with him and lost my stubborn 10lbs that I couldn't lose by other means. Highly recommend this trainer & nutrionist!! read more

Performance training center has changed my life forever. I was able to put on 20 pounds of muscle in a healthy fashion. I have never felt better. I would recommend their unique methodology of getting results. I have a co-worker who lost 18 pounds in 2 months without starving herself. She looks amazing and has kept the weight off for the past 6 months on her own. Just one of many examples of the great impact that a knowledgeable trainer/nutritionist can provide. read more

I recently decided to shed some extra pounds and get healthier. I contacted Martin and he recommend a few helpful products from his website. Wow, I was able to lose weight and increase my energy levels, after only 14 days! I am now on the maintenance products and continuing the journey. It's been a long time, since I have felt a sense of peace and wellness within my body. read more

I have been working out with Martin for about 2 years now and he has made a tremendous difference in my strength, posture and overall health. He has an amazing ability to spot slight differences in position and mechanics and get you to correct these. He also is constantly changing things up to keep the workouts interesting and my muscles and and brain integrated. He is very motivational as well. Of course it doesn't hurt that I would like to have a body like his! read more

Martin Alonzo has CHANGED my life! After asking my Physical Therapist WHAT she was doing to look SO different from the year before---buff, 20 years younger and glowing...she handed me Martin's card and said: "go see him"...so I did. YAY for me!:-) Best decision I have ever made. I have been working with Martin for 4+ months and I have never felt better in my life! I am 56 years old and I was losing my strength...it was harder to get out of a chair, I couldn't open jars, I couldn't carry heavy grocery bags etc etc. NOW I am doing 45 lb deadlifts, 15lb bicep curls and I have lost almost 25 lbs! For a gal in her late 50's that is REALLY SOMETHING. By testing my blood and urine, Martin was able to determine why my body was so out of balance, so we changed my diet, went on QUALITY supplements and are training my body the correct way. I have never ever known anyone who knows the human anatomy like Martin does. Every move I make he makes sure my body is in perfect alignment to get the ultimate benefit both in cardio and muscle toning. If you are reading this Martin, THANK YOU from the bottom of my heart for changing my life and giving me the confidence I had inside of me. Run (if you can ;) don't walk because this man is amazing! read more

I am a guy who considers himself athletic, but I have never worked out in my life. I had to learn from the basics of breathing to coordinating movements I've never done. This was not a challenge for Martin. Over the last year he has transformed my posture, strength, stability, and overall lifestyle. Martin is a talented personal trainer who takes time to learn your goals and then helps you find the path to achieve that goal. Martin is not just a great trainer, but very knowledgeable about the human body as well. I look forward to my workouts at Performance Training Center and would highly recommend this place. read more

Martin is a top notch personal trainer. I came to him seeking help rehabbing a chronic shoulder injury I've had trouble correcting on my own. Martin spotted some muscle imbalances that had been causing repeated re-injury. After two months, my shoulder was considerably better and I was able to get back to a more active lifestyle. Enjoying his approach and knowledge in every aspect of working out, nutrition, and preventative maintenance, I have continued to work with Martin going on 6 months now. My strength, flexibility, and endurance have never been better. I highly recommend Martin to anyone looking to achieve their fitness goals. read more
