I started training with John Fasulo after a lower back injury took me out of heavy lifting for about 9 months. He told me his goal was to "pour the concrete" to restrengthen my core, help prevent injury and gain strength. He put me on a program called GP - Athletic Strength. The program had a mix of stability, mobility and strength exercises.

I had never realized how much stability and mobility played into building strength. I really enjoyed using the app John programs workouts on to track my progress. It allowed me to challenge myself even more with each workout. Each workout phase

If you are cleared physical therapy, recovering from surgery or an injury I highly recommend John. His knowledge and experience was extremely helpful in my recovery process. We focused on core strengthening, balance and light weight lifting while maintaining excellent form and posture.
We discussed my full medical history and John was aware of all my concerns throughout our training program. I highly recommend him for whatever type of training you're looking for.

I've been training with John for a number of months now, he was recommended to me a while after a shoulder injury that has been bothering me for some time. While training I've been able to learn a ton about how the body works, and have been taught a number of new exercises and movements that have really improved my workouts and rehab past injuries. He's extremely knowledgeable and passionate about training and I would highly recommend working with him

I trained with John Fasulo for almost a year. I have trained by myself for years, so I have a high standard for my trainer. However I have to say that John is indeed a super expert in his area. I really wonder where he picks up so many training method for all aspects of your body, strength, flexibility, agility, explosion and so on. John's training helps me to improve my performance in other sports like swimming and boxing. Really have a lot of fun with him.

I trained with John Fasulo for about 8 months. John is truly an expert in his field and I enjoyed every session. He pushes you to your limits but understands your limits. Ever session is a bit different and tailored to you body, strengths and weaknesses. I felt my body responding and getting stronger with every session. Looking forward to working with him again at some point. He is an extremely knowledgeable trainer.

This gym is for Torrey Gardens apartments residents. It’s clean and has a wide selection of cardio and weight machines. There are various classes offered here like yoga, zumba, mat pilates and cardio barre. There are water fountains and shower rooms. There is a personal trainer option available here. It’s open 24 hours. There is free wireless internet to use. The cardio machines have a big screen display where you can watch YouTube, scan Twitter, or listen to music.
The only problem with this gym is that there is no mobile phone signal because it’s under the ground. That means you will be

John was my personal trainer for over year. When my daughter moved here, he worked with us together. John is extremely knowledgeable about the body and nutrition. He never asked me to do anything that he wasn't willing to do himself. I'm in my mid-50s, and he treated me with kindness and respect. However, he didn't lax up on me when I tried to pull the old lady card:-). I truly enjoyed working out with John. He taught me so much, and I still use his training tips today. I highly recommend working with John. He will get you into your best possible physical self. Plus, he&apos

One of the Top Trainers in San Diego! I started training with John more than a year ago and due to some injuries/issues that left me feeling like I couldn't get back to my normal exercise or gym routine without at least getting "fixed" or better first! I had incredible improvement in mobility after every session (neck/arm/back issue) along with long term results.

We worked around my injuries and through them in order to ensure progress. John's level of expertise and credentials in this area is unmatched. He helped fix what many doctor's, chiropractor's and physical

Athletic & Aesthetic Fitness motivates me to want to work out, not even kidding. I have been to pretty much all gym's in San Diego County and this one has a special place in my heart.

I started training with John Fasulo about three years ago, he is always prepared for every training session. The workouts were always challenging and fun at the same time. He has an amazing balance of being able to push you to get the most out of your training without screaming at you or feeling like you accidentally joined the marines. My weekly sessions are something I look forward to every week, and am

I started training with John months ago after a surgery weakened my body and have had great results in such a short time. I have previous sports injuries and he was able to work around those while still producing results. He came up with multiple different ways to work the same area while progressing the difficulty with my growth. I was sad to have to stop training with him due to a job relocation. He's very knowledgeable and I would definitely recommend John to anyone.

I started training with John Fasulo about two years ago, but got serious about weight loss and healthy eating in November 2016 after a health scare.
My main goals were (dramatic) weight loss, weight training and general health improvement.

In November 2016, I was obese, out of shape, and not well educated in nutrition.
One year later, at age 60, thanks to John's diligence, motivation and skill, I have lost 45lbs, am no longer in the obese range, and all my health issues have resolved themselves.

Also, thanks to John, I have shaved TEN minutes off my walking speed, from a 24 min mile when

I've been training with John Fasulo for almost two years. My main goals were to tone up, lose a little body fat and build strength. When I first started, I was only really familiar with using the elliptical, the stair climber and the occasional treadmill run. As a beginner, he gave me a good introduction into utilizing the TRX machine, basic weights and plyometrics. I had trialed another trainer and some group classes in the past, but I never felt like I was getting much out of it nor that they were teaching me anything. With John, he was great at explaining what muscle groups each new exercise
