Working with Marta has been an amazing experience. She has been so helpful in designing and coaching me through our sessions. This is my first experience working with a personal trainer and I am so happy it is with her!

My training experience with Marta has been great!! she has brought me through workouts that I feel like push me but are also well suited for my fitness level. She is super sweet and clear and it feels like just the right amount of instruction and feedback. We also talk about diet and what I do when I’m not training with her. The workout goes by fast and doesn’t feel like I’m working out! Definitely recommend

I really like working with Marta, she pushes me, but also understands if I need an extra break. She is very informative and I already learned so much! I highly recommend her as your next personal trainer!

Marta is extremely knowledgeable, professional, and motivating. She goes above and beyond to help her client. She makes sure they are comfortable with what they are doing, and knows how to do it. She totally kicks my a*s and makes me look forward to working out (insane, I know!!). Marta takes the time to understand her clients lifestyle and goals, and helps educate them in order to reach those goals. I’m so excited to continue my fitness journey with Marta, I truly couldn’t do this without her!

I contacted Marta to help me get in shape for my wedding in June. I have been seeing her in person and virtually since the start of December. We personally discussed my goals & moving forward, each time she has had a killer workout planned for me even when i’ve had limited equipment. Not only is she amazing and extremely knowledgeable but she really pushes you! My first session, my legs would shake trying to squat but now I’m able to pop, lock & drop it. HA! no joke. My body feels more active and not so tense. Her constant motivation is a reminder to why I started this journey in the first place and it keeps me going. I highly, highly recommend her!

  • What should the customer know about your pricing (e.g., discounts, fees)?

    You receive a free session for every new client that you refer.

  • What is your typical process for working with a new customer?

    When we first meet I like to spend some time on getting to know each other, answer any questions and address any concerns. I do a body assessment, discuss your goals, diet and medical history. We also do a full body workout.

  • What education and/or training do you have that relates to your work?

    I received an Insanity certification that helped me jump start my fitness knowledge. I later went to the National Academy of Sports Medicine to deeply understand human anatomy and body mechanics; I received a NASM Certification.
