Fantastic! Marc is a positive and down to earth personal trainer. His social media content is super helpful for individuals that need that extra push to stay motivated during their fitness journey. Give him a follow and if you're in the San Diego area, DM him to get on the schedule. Thanks! IG @body_by_barron_sd read more

This is my first official Yelp review so here you go! I've been training with Marc on and off since 2015. It was definitely a struggle to workout when I wasn't training with Marc. He always keeps me accountable even though with my busy work schedule, he has always given me the flexibility to switch my gym days. One of my favorite parts of training with him is being able to have semi private training. I've made some good friends here and I'm sure these friendships will continue outside of the gym. I try my best to train with Marc 2x a week and I have noticed a difference in my energy levels! Even though I may not agree with some of the exercise *cough cough* bear crawls, I've noticed an overall difference in arm definition as well as my booty gains! Squats squats and more squats! He always makes the workouts fun and never boring. He has helped me to incorporate some of these workouts on my non gym days. Thanks Marc! read more

Best a** kicking workouts I've ever had!!! I have had many other trainers at gyms like 24hr and world gym and never have any of those trainers pushed me as hard as Marc has! I have been training with Marc on and off for 5 years and this year has been the most consistent one yet. Many people have told me don't do weight training you're going to get too muscular and look manly. That is far from the truth, this is a lifestyle change and honestly weight training isn't for everyone. But I'd rather deadlift than hop on that treadmill and run. Training with Marc has honestly been one of my best decisions, he pushes you harder and harder each time, just when you think you've done it all he hits you with an even bigger challenge. He provides semi-private sessions which are great because not only is he pushing you to get stronger and to do better but also because you begin to build relationships with your training partners and you start to motivate one another as well. Also if you're a bride to be who needs to get wedding dress ready Marc's your man! I've personally seen his bride transformations and he's going to help me reach my wedding goal for next summer. read more

I began training with Marc about 5 years ago. Prior to training with him I had no idea what I was doing at the gym. Marc set me up on a meal plan and a workout plan that was very effective for my body. Training with Marc taught me how to properly workout to avoid injuries, gave me to confidence to workout with weights, and taught me that eating clean doesn't have to be boring - All while having fun! During those 5 years I've had 2 knee surgeries and have fracture my foot as a result of old injuries or accidental injuries on my own. After my knee surgery and fracture I didn't think I would be able to get back in the gym and work out as I did before. However, Marc helped me rehab those injuries and I was back to working out just as did before with no pain or discomfort and even feeling stronger. I have moved away and cannot train in person with Marc, but he does offer online programs. So it's awesome that I can still continue a workout plan set up by Marc. If you're looking for a trainer that will not only make working out fun, help you reach goals, challenge you, teach you proper workout mechanics, and/or help you rehab injuries - then Marc is the trainer to hire! read more

Training is almost fun! He's a great trainer. You'll get results, trust me! Marc is pretty great with any kind of questions. Even for something so little. He has a lot of knowledge. The training has still been hard even though a lot of it is outside now due to COVID but he makes it work. If you're having trouble with an exercise, he works with you. He wants you to feel comfortable. I love training with him. I have been for at least 6 years and I will continue. He also helps out a lot with questions on Social Media and has these 6 week challenges you can participate in if you can't come in for a training session. read more

I've been training with Marc for a couple years now, and it's been one of the best choices I've ever made! I HATE working out, but having Marc helps keep me accountable. I got married a couple months ago, and a few days before my wedding, I hadn't shown my face in the gym for about a week, so he texted me to shame me for not working out. (now if he could only follow me around and smack food out of my hands) LOL.. I really don't enjoy working out, but having a trainer definitely helps keep me accountable. Like other people mentioned, Marc tries to work with your schedule, and is super flexible because sometimes things just come up. I really like the semi private training because its just fun to be able to work out with other people. I definitely get my moneys worth, because I've had some of the best kick ass workouts!! Also, my husband has just joined, and Marc is going to whip him into shape!!! read more

I have been training with Marc for about a year and a half and I can't say enough good things about him! I came to him after two years training under another coach and just kind of exhausted with the training regimen and boring meal plan I'd been following for almost as long. Marc made working out fun and exciting again also really helped me to learn about properly tracking nutrition, not just following a meal plan eating the same thing over and over. He keeps the atmosphere fun and supportive, but don't think that you're not going to put in work! Every workout is challenging and you will be pushed to do your best. My training days have become such an integral part of my personal routine, I will actually plan my days around whether I am training or not. I've gained so much strength training with Marc and am so thankful to have his wealth of knowledge around training and nutrition so I can continue pushing myself. Whatever your personal goals are, Marc is happy to work with each of his clients to tailor their training to their own desires, not just a one-size fits all kind of program. I am confident that anyone wanting to commit to a fitness routine and have access to someone with quality information and know-how will love working out with him! read more

Marc is one of a kind! I was in a really bad place and it was hard to look at myself in the mirror. At Fit4Life I've learned how to push myself. I was able to lose 25lbs in about two months thanks to the workouts and meal plans. Not only do I feel better physically but mentally stronger as well. Marc instilled more confidence in myself. The gym is super clean and everyone else that works out there is super kind and encouraging! I can't say enough good things about Marc and Fit4Life. read more

Marc has been an excellent trainer for me. He constantly keeps me motivated and accountable. He will see my social media and tell me to stop being irresponsible haha which I love. My business hours fluctuate everyday and Marc has been incredible at being flexible with my schedule. Of course he keeps me accountable with the time we agreed on but if I need to come in another day or time he has always accommodated. Highly recommend read more

My son races BMX and recently joined a small group of riders in Marc's program. After just one "tryout", my son and I could tell Marc's dedication to his craft was nothing short of amazing and we had to sign up! Since my son has been training with Marc's group, he has shown a massive speed increase in his racing. He is versatile in his clientele, adhering to many different sports and lifestyles. His flexible schedule and knowledge base are 5-Star alone! Give him a chance to show you what he's all about, you won't regret it. read more

First time EVER training with a trainer and I can't say enough good things about him. Only been seeing Marc now for 3 months and I feel great. He's great at what he does and he really pushes you to your limits but not in a way where you feel like he's a drill sergeant. Work out routines are always changing which makes working out not boring at all! If your like me and never had proper training go to him, you'll learn a lot! read more

Marc hands down has been the best trainer I've trained with (hence why I've always come back to him after taking a few breaks from training). As someone (me) who suffers from an ACL injury he's helped me strengthen muscles that have allowed me to prevent further injuries. Marc is: knowledgeable, a great motivator, very professional and has a great attitude. I've never left a training session disappointed...in the past have recommended Marc to friends and family and I will continue to do so. Thanks for helping me reach my fitness goals Marc! read more

I've trained with Marc on and off for 5 years now. His prices are affordable & he helps you get the results you want. He's extremely knowledgeable & just a great person over all. I highly recommend him as a trainer for someone at any stage in their fitness journey. I've worked with him as I was recovering from an injury & postpartum. Each session is different so it never gets boring or feels like a routine. read more

I found Marc on Instagram and started training with him about 3 months ago. This is my first time working with a trainer and in these short months, I've noticed how strong I really am! Each workout is different which makes it fun, so you never get bored. I've also lost inches around my waist, my clothes is fitting better and I'm actually eating food thanks to his workout plan. I would definitely recommend Marc to anyone looking for trainer who knows what they're doing. thanks Marc! read more

I've been training with Marc for over 5 years now and I've been in the best shape of my life since meeting him. The hardest part really is just showing up! Marc will help guide you to meet your goals whether it be weight loss, strength gain, or rehabilitation. He has helped me go from 300pounds down to 190 within a year and has helped me put on about 30 pounds of muscle over the past few years. He is without a doubt the best trainer in Chula Vista. read more

I'm in pretty great shape on my own, but I lack formal training knowledge. What makes the difference between results and stagnation are the details - am I at the right angle, is the motion smooth and natural, am I using weight that's challenging but won't cause injury, how do I still gain results while nursing an injury. These are the details I get when I train with Marc. Details matter bc details bring results, and a lot of people don't emphasize the importance of the details. But my favorite part about working out with Marc is that our workouts are never the same. It's always fresh and creative, usually incorporating new movements and positions that I've never tried before. This not only helps prevent plateau, but it honestly just keeps it fun and exciting...like let's see what this fool will create today. Most importantly, it's always good energy; always good vibes . read more

I trained with Marc for about 5months. He guides you through nutrition plan and various workouts that target different parts of your body. He reviews what your goals are and helps you attain them. He's awesome because he will give you a different variation if you're hurt or need help with a certain body part. He also does online coaching if you can't physically make it. I've always wanted to train with a trainer and i finally did it! I'm glad and grateful i was able to experience it because it really does make a difference with your form and setting up a routine for yourself. (at least for me) I trained with a friend and it was super cool because we kept each other accountable. 11/10 recommend if you want to try out personal training. I am no longer training with Marc due personal reasons but I would go back in a heartbeat if i could. If you're thinking about it....just do it!! Invest in yourself. You're mind and body will thank you later. read more

Marc is an amazing trainer! I say that because I have lots to compare too. I've tried the conventional gym as well as personal trainers that have been recommended to me over the years. He works diligently on helping you reach your goals always changing up the routines keeping them challenging. Small groups help encourage and motivate each other. I have personally seen a change in my body and have gained strength and endurance. If you are looking for a trainer that challenges you and keeps it fun this is your guy. read more

I found Marc through a friend 2 years ago I was focused on losing 15 pounds and toning I was able through Marc's expertise and knowledge meet my goals and have been able to maintain , but little did I know the mental impact it would have on my life no one knew the depression I was facing and going through so blessed to have found out through hard work physically and making healthy choices that it would be a positive for my mental health Thank you Marc for always pushing me to be better and getting me out of my comfort zone I'll always be grateful #nevergiveup read more
