Andrés Venezia

Strength Training Client

Client Testimonial

"Working out with Mariano has been, by far, my best experience with a personal trainer. I’ve had a few in the past, but the progress I’ve made with him is noticeably greater than with any of the others. He has helped me tremendously and continues to help me every step of the way. On top of that, he’s a great conversationalist, overall, the best trainer I’ve ever worked with."

Parker Pacífico

Strength Training Client

Client Testimonial

"I needed a trainer that had an approach with an understanding of my body’s needs, since I am a senior and have developed arthritis. Mariano’s trainer experience, physio education, and his sincere and concerned personal individual attention and guidance to my needs, have been above and beyond my expectations. His pleasant personality makes every session enjoyable. I can’t thank him enough for my continued strength and health improvement. He is the best!"

Juanita Mejía

Fitness Client

Client Testimonial

"Training with Mariano has had a huge impact on my mental health and my horseback riding career. Not only do I absolutely love working out and enjoy every training session, but I can also see significant improvements in my strength and shape. He takes the time to ask me about my sport and its demands, and is therefore able to focus on every muscle. He is also very careful about my injuries and has a lot of knowledge on this, which makes me feel comfortable and confident that I won’t have any further injuries. It’s been a blast!"

Theresa Johnson

Mariano became my Trainer and everything has changed drastically for me in a positive way. Mariano is very professional and well trained. After 5 months of training I have strength that I never believed I would have. My body has noticeably changed. I WILL RECOMMEND MR Mariano to everyone. "
