The "WHY" Behind MMX Training Systems. We Are "ReDefining The Online Exercise Experience".

Training is teaching, or developing in oneself or others, any skills and knowledge or fitness that relate to specific useful competencies. Training has specific goals of improving one's capability, capacity, productivity and performance. A system is 
a set of things working together as parts of a mechanism or an interconnecting network...A set of principles or procedures according to which something is/or done.

I started this website with the idea to give the consumer an online resource void of all the nonsense and inaccurate information that is plaguing the exercise/fitness/rehab industry. My mission has always been to cut through all the bulls*** and provide you with an intelligent training platform so that you can thrive, excel, and endure the physical demands that daily life throws at you. Inside you will find several "Training Systems" that will guide & help you achieve whatever goal you may have. Everything from pain relief, athletic performance, customized exercise prescriptions, better movement, etc. Every "course" is laid out for you in a progressive manner. They are extremely easy to follow and enjoyable. We are here to guide you every step of the way. If you have any questions please don't hesitate to send me an email. My email is located in the bio section. I hope you enjoy the site and welcome to MMX Training Systems, the future of online training. -Founder, Dominick Nusdeu

Success Stories

“"A Grateful Client I had been suffering from back and neck pain for 8 months. The tightness caused terrible headaches in the back of my head which would make it very difficult for me to function. I tried physical therapy and saw a chiropractor for months. I had also seen an orthopedist who after looking at my x-rays couldn't determine the cause of the problems; he only gave me muscle relaxants. It wasn't until I started working with Dom that I obtained relief from my problems. My husband, who was also seeing Dom for various work and exercise related problems, suggested it to me. I saw that it was helping my husband and, not knowing what else to try, I decided to give it a shot. I'm so glad that I did! After a few months of regular sessions, I am doing much better. My muscles are stronger and I rarely get the headaches anymore. The best news is that after a year of not exercising, I have started to work out again! Dom is very knowledgeable about how the body works and confident in his approach. He really listened to my description of my problems and really cared about helping me feel better. He went at a pace with which I was comfortable. He is very pleasant and fun to work with, and I always feel good after our sessions. I will always be grateful to Dom for helping me feel better and be able to participate more in my life." ”

“"I highly recommend Dominick Nusdeu and Motion Mechanix. I am a professional violist, and for most of my 30 years of performing and practicing, I have experienced chronic pain. Recently, I thought that I was going to have to give up playing because of a pinched nerve in my neck. Chiropractics and massage helped somewhat, but Dominick completely relieved this problem and other issues as well. In my opinion, it's a miracle! Dominick's incredible precision gives me instant and sustainable results. I now practice for hours and perform virtually without pain or discomfort." Sue Corey-Sahlin”

“"Just had my 5th session with Dominick today and i’m already seeing outstanding results! After each session I feel a little bit more whole, a lot stronger, and more like a normal person. I am now walking an extraordinary amount which I was never able to do without pain, swimming, hiking with my son and enjoying life again. I really cannot thank Dominick enough. I highly, highly recommend him!” ”
