Weight training has been Monica’s passion since the age of 15. She has always been athletic and played sports throughout high school and college. When she moved from Venezuela, she remained active by becoming a personal trainer. Her goal is to teach others how to be active and stay fit! She tries to live by example and make an impact on her clients’ lives every single day.



Jose loves helping his clients achieve their personal training goals. He strongly believes that together we can create a healthy lifestyle and the body we want.



Rachel is a NASM certified personal trainer who has a “mind over matter” mentality that she translates into her workouts. Her goal is to push you, hold you accountable, but still be a supportive, attentive, and caring coach.



As someone who went from underweight to healthy, I want to show clients that lifting and a healthy lifestyle are essential to living a full, happy life no matter their body goals. My goal with each client is to push them to be their best selves, support them through the process, and to hold them accountable as they reach those goals!


"I been coming here for about 4 months now and I have been absolutely loving it. I needed this type of accountability in my life. I feel so much stronger compared to when I first started it's crazy. Alejandro is my trainer and he kicks my ass every time. I told him my fitness goals and he definitely is making me achieve them. I highly recommend this gym and the environment is like no other."

"I love Four Fitness! They've changed the way I think about fitness. I train with Marcisco 4X per week. I've improved my form and have fallen in love with lifting weights. I used to be a cardio bunny and never saw any kind of lift or tone in my body. I can slowly see my shape changing and best of all, I'm getting stronger. It's a sense of community here, all the trainers are friendly and super sweet. I come here after an intense day at work and just relieve the stress! I will work out at Four Fitness for as long as I can :- )"

I came in for a complementary 1st session and was paired up with Monica. That 1st day I knew! This was it! This was my chance to start something that I had always feared.. strength and functional training. Monica spoke to me for a bit and got to know what I needed and what I was looking for. She then had me do a couple sets of different exercises and I felt amazing after. I did some exercises I didn't think I could ever do.
