12 Weeks To Transformation

The road you are on is process my friend.

I am not going to lie. Most who start this road WITHOUT what I teach, fail within a couple of weeks.

They start doing yoga thinking that a little stretching will fix everything in their body.

Starting with the intention of doing it EVERYDAY.

This lasts exactly 1 week.

Then after that week because that's just too much yoga for a beginner, their body gets blown out or they tweak themselves worse then why they started..

And they quit for a couple of weeks and then try again.

And fail...

Over and over and over again.

After working with people just like you for 23 years, I have learned that it's because they lack the structure, mentorship and SUPPORT to succeed.

Getting your body back takes time and consistency.

That the secret sauce we use in our 12 Weeks to Transformation Process.

Now it's NOT a magic pill.

It will take focused effort..

But it will create amazing changes in your body.

Here is what we are going to make you do..

Kind Words From Our Students..


Stacy's Story:

Body Tonic has had a profound positive impact on my recovery and mental well being since I’ve been going class. and it’s only been three months. 

 To say that the Brian and Body Tonic has been a game changer for me is an extreme understatement. Last December I broke my ankle and fractured my tibia in 13 places (it was a Pilon Fracture). I was non-weight bearing, on bed rest, for 3 months. That was followed by another 3 months of gradually increasing the amount of weight I could put on my left foot. That process took me from a walker, a knee scooter, crutches and finally a walking boot. 

 On August 8, 2018 I went to my 8-month check-up with my surgeon and received a devastating diagnosis. That was that my range of motion would likely not improve EVER. At the same time my physical therapist discharged me from my weekly therapy because she felt there was no longer a value add to my recovery. It was a serendipitous 3 days later that someone in my apartment building who had seen me through my stages of recovery told me about the Body Tonic. 

 I called Brian the next day. He asked about my injury and my recovery to date. Brian’s response was respectfully, he wouldn’t accept the diagnosis of the surgeon and that he could help. He said it would just take time and dedication on my part. I went to my first class that same day. I’ve been going to class regularly and have seen and felt a radical improvement in my ankle range of motion, the strength of my ankle and foot and my walking stamina. Before I started going to class, I was limited to a few block walking radius. Today, I don’t have those limitations. My journey so far has been fantastic and I am so thankful for my improvement. But what’s even more exciting and motivating is that I know my journey and recovery is really only starting now. I couldn’t be more appreciative of the amazing space and experience that the Body Tonic has given me.


Mitzi's Story:

When I walked into Brian’s studio in March 2009, I was recovering from my third knee ACL surgery and was just diagnosed with severe spinal stenosis and sciatic leg pain. I also just had in the 2 months prior, 2 epidural procedures to relieve the pain in my lower back with no success. I was going to physical rehab twice a week, having massages, was on all kinds of pain medication and no relief. My back doctor told me that if nothing was working, our next step was surgery with no guarantees. I was slowly going into a depression and spent a lot of time in bed, could barely walk, move and was in extreme pain 24/7.

My life slowly started to change when I met Brian. I discovered his studio after having lunch at Delfina where I was trying to eat away my worries. I read the testimonials on his wall, checked out his website and liked the fact that he specialized in people with injuries. I had tried all other remedies for my back with no progress so what did I have to lose? The $30 unlimited offer didn’t hurt either.

Brian was great from the very first day I walked in. He asked me all kinds of questions regarding my injuries and assured me that he would be able to accommodate my restrictions. It was not easy for me in the beginning as I was very limited in my range of motion. This was quite frustrating for me since I used to be a very active person prior to all my surgeries. I used to work out with a personal trainer twice a week, run/walk, ski. Brian just kept on encouraging me and showing me ways to do the poses so as not to aggravate all my other ailments.

I have been coming to Brian’s studio for almost a year now and what a difference he has made in my life. I try to come at least 5x a week. All that practice has paid off because now I stand straighter, more flexible, stronger in the core, no more back pain, lower blood pressure and the upside is I have lost almost 20lbs. This is great since it is putting less strain on my joints. I still limp from my sciatic pain but my doctors have told me that this takes time and that I am on my way to hopefully being pain free! I am no longer going to physical therapy because Brian has taken me to another whole level that therapy could no longer give me.


Sydne's Story:

Back in September, I was faced with a decision. As I was approaching my 26th birthday, I was already starting to have daily knee pain and hip pain. I had tried and failed to “lose the weight” since middle school. I had tried all sorts of different diets and nothing stuck. I had two choices: keep going on the path I was headed down or make a permanent change. I knew I didn’t want to end up with type 2 diabetes and mobility issues, I knew I wanted better for myself. I decided to take a serious look at my health, drop the excuses, and really go for it. 

This time felt so different because I was finally doing it for the right reasons. I wasn’t trying to fit into some new dress or to look like the girls in the magazines, I was doing this for my health. My goal is to be strong and fit and to FEEL BETTER–no longer just to look better. I started making changes to my diet, drinking tons of water, and fearlessly trying new forms of exercise. I signed up for Brian’s Transformation Camp in October, and it really helped to put me on the right foot on my journey to fitness. I feel so much stronger and more active than I was even just a few months ago. My body can do all sorts of things it couldn’t do before, and I’m so excited because I know this is just the beginning. I already know what happens when I quit, so this time I’m going to see what happens when I keep going


Aaron' Story:

I’ve never been a new-agey or eastern philosophy kind of guy. I don’t know if my chakras are aligned or what would happen if they weren’t (it sounds terrible!). I’ve never been into astrology, although that kind of skepticism is pretty typical of a Sagittarius. My friend had to drag me to my first yoga class at Body Tonic. It just didn’t seem like the kind of thing that would appeal to me at all.

My first class with Brian had no drum circles or meditation, but was an absolutely brutal workout. By the time we got to the ab series I was praying for the either the end of class to come or the sweet, sweet release of death. But I survived, and came back. I have never found any sort of exercise that didn’t bore me quickly. Brian doesn’t just tell you to do things, he tells you why. He recognizes your specific problems and how to work through them. In my case, my problems started with my freakishly flat feet. Yoga has helped me rebuild my arches which were causing other problems throughout my body. Yoga has also helped my fitness overall dramatically. I’ve lost over 40lbs in the last year from doing yoga and eating more of these things called “vegetables” which is apparently food that grows right out of the ground (yeah, I’m not fully sold on that yet either).

Brian and the classes at the Body Tonic have, quite literally, changed my life. Bill’s classes on the weekend are no joke either. He also won’t let you settle for anything less than your best effort. At first I was just looking to get into shape, and now I really want to understand and get better at the poses. And who knows, maybe there is something to that mental calm thing after all. Since I’ve started yoga, I have no longer felt it necessary to create a monkey army to destroy my enemies. I’m joking of course — that would be really impractical. It’s quite difficult to find monkey sized military fatigues.


Wendy's Story:

I remember when this was taken. I certainly didn’t start yoga being able to do this. I remember being so stiff and out of shape that achieving this pose seemed impossible. I used to have a recurrent upper back injury and horribly painful and crackling knees, both of which were worsened by every day stress and being overweight.

When I first started practicing yoga at Body Tonic, a good portion of the poses had to be modified because of my injuries and limitations. I was quite wobbly, very stiff, and, thinking back, probably laughable. Through constant adjustment and coaching, Brian helped me to become stronger and more stable and to do more than I ever thought I could.

After just a month, I noticed my posture was better, I had more energy, and I generally just felt better. After six months of going to class three to five times per week, I had lost 27 pounds and started re-shaping my whole body. I was becoming stronger and more flexible each day, not to mention calmer and more focused in my daily life and yoga practice. Over the next year and half, I continued to lose inches and build muscle in my hips, shoulders, arms, chest, ribs, stomach, and thighs. Yes, getting into smaller sizes rocks! Through consistent practice, my whole body got stronger, my upper back no longer hurts, and daily stresses just don’t bother me the way they once did.

I don’t just love going to yoga, I look forward to it. While many exercise trends, fads, programs come and go, I can see myself doing this for a life time. Thanks Brian! You changed by life!!
