What is MAT? 
Muscle Activation Techniques (MAT)® is a powerful muscle tool that analyzes and corrects muscular imbalances. MAT® is designed to re-establish the communication pathways between the nervous system and the muscular system in order to restore muscle contractile capabilities in under-active tissues. When balance to the muscular system is restored you will feel better, move better, have increased mobility and be able to reach new levels of performance.

When should you use MAT? 

The best time to try MAT® is when you notice tightness or chronic discomfort issues in your body. MAT® is effective for active people, as well as those that are awaiting surgery, or coming out of a medical procedure.

Muscle Activation Techniques

MAT® looks at muscle tightness as being a symptom that relates to underlying weaknesses. When there is too much stress or trauma in an area of the body muscles won’t contract efficiently - they actually weaken due to lack of neurological input. This causes opposing muscles to tighten up.


Many modalities focus on trying to loosen up the muscles that are tight. With MAT®, we focus on the muscle weakness aspect of dysfunction. Through specific use of activation techniques, not only do the associated muscles get stronger, but the protective tightening of other muscles goes away. MAT® works to improve a muscle’s contractile capabilities and the result is more range of motion and strength from that muscle & the corresponding limb. By improving these aspects, a person will see an increased ability for exercise and physical performance.

Client Testimonials

Charles dug me out of a serious hole. I'd been struggling with extreme sciatic pain in one leg for over a year when I was recommended to Charles at Muscle Activation SF. Before starting MAT, I'd been through extensive massage therapy, acupuncture, conventional PT, yoga, pain meds, etc. etc. etc. Hugely expensive, hugely unproductive. Could not walk more than twenty feet. Could not sit at all.


I've seen Charles 9 times so far. Last week I did fifteen miles of hiking in Yosemite. Enough said. You'll be amazed by what MAT can do!

Charles Lantz is incredible. I have struggled with back, hip and glute issues for almost 20 years. Seen every specialists in town - surgeons, pain specialists, nerve specialists, osteopaths, physical therapists, prolotherapists, chiro, PRP, dry needling, yoga, trainers, acupuncture, cupping, active release therapy, etc. Nothing worked. Charles was able to evaluate me and assign home exercises that provided relief and hope within days. I am now back to all of the sports that I had given up for dead. His process is both complicated and simple. Complicated in that Charles picks up on structural misalignments and muscular compensations so quickly that it is revelatory and almost mysterious. Simple in that if you just do what the dude says to do then you will be cured. Save yourself time and money. Go see Charles!

I love MAT and cannot recommend Charles enough! have been working with him for a few years now and could not be more thankful for him. I had been suffering back aches from an old injury for many years. When the aches increased and sever foot pain kept me from running for many months, I decided to try something new. I saw immediate results after my first session and appreciated  his honest approach to treatment. The treatment sessions combined with the at-home exercises helped me feel great in just a few months. For someone who had resigned herself to constant back aches forever, it was liberating! I continue to go every 4-6 months when feel like my body could use a little tune up and refresh my exercise routine. I highly recommend MAT to anyone with chronic issues and for those just looking to feel balanced and strong.
