Michael has been very helpful in building a new routine and teaching me new exercises. I had been working out for a while on my own but I needed some help getting to the next level. Michael had provided good insight and techniques to help improve my workouts. Having access to the app allows me to track my workouts and my calories. Michael checks in regularly throughout the week and continues to monitor my progress. I look forward to more sessions and seeing the progress over the next few months.

I trained with Michael for 6 months. He challenged me every session we had. I would leave every session with a sense of accomplishment, having outperformed my own expectations. Michael listens, reinforces positive habits, and tailors workouts to your individual needs. When I was dealing with shoulder injuries, he helped me work through them safely by modifying exercises and focusing on proper movement and recovery. His knowledge, encouragement, and attention to detail helped me become stronger and more confident in the gym. I highly recommend Michael to anyone looking for a trainer who will support, motivate, and challenge them to reach their goals.

I would like to share how amazing it has been to work with my personaltrainer, Michael Castaneda. I was hesitant to work with a trainer due to past experiences but Michael has helped me jumpstart my fitness journey by challenging me to get stronger everyday. He is very knowledgeable and fully dedicated in helping his clients succeed. Michael tailors his workouts for my specific needs and my limitations.
Stepping foot into the gym can be so overwhelming but since I started training with Michael, I feel stronger and more confident in my workouts.
If you are looking for a professional trainer who will help you reach your fitness goals, Michael is the person for you.

Michael helped be strengthened my weak flexor which helped me understand how to exercise it. That helped me gain strength in my legs, and improved my back squat. I’m grateful for Michael’s passion and patience. It was a great experience working with Michael and recommended him for correctional exercise.

I worked out with Michael for close to a year and he helped me get back in shape, as well as helped me work through and heal from different injuries post having a baby. In the time I knew him, I dropped from 160lbs to 148lbs, and became stronger and more confident in my body. He also taught me a lot about fitness in a holistic sense, always balancing strength, flexibility, endurance and mind-body connection. A trainer like Michael is truly one in a million, and I can say this with confidence as I have had many, many trainers over the years I've been working out, and none come even close to his expertise and knowledge, and just sheer positive attitude.
