Real Results from Real People
Posted on Julius FischerTrustindex verifies that the original source of the review is Google. I am not an athlete, but a musician in my in my mid 60s – probably not Zach’s typical client. I’ve spent a lifetime of being hunched over a piano and in later years, a computer keyboard. About 9 months ago, I started having pain in my right shoulder, and it hurt even to lift my arm straight out to my side. I came across a video of Zach working with a pitcher who had injured his shoulder, and his approach really made sense to me. I was encouraged, both by the thought of getting relief from the pain, and the idea that I could have a professional trainer give me guidance to establish an effective full body workout that would allow me to continue to be active. I decided to purchase the six video package, and I’ve been working with Zach for 3 months now. It’s often the case that we are more quick to notice when something hurts than when it doesn’t hurt, and two weeks ago, I helped my daughter and husband move into a new house, and I realized, my shoulder does not hurt at all! This works, and I’m still in the first level of exercises. I can see that this has tons of potential, and I am very excited to see my further growth. Even with just working those underlying muscles and building a foundation, I already notice that I carry myself differently. I’d also recommend doing the video sessions which I have found to be invaluable. Not only is there a learning curve, but as the muscles develop, there are adjusts that are required to continue to get the maximum benefit. I have appreciated being able to go back and review the sessions to watch what I did and to hear his instruction, which is very precise. I then use Zoom to video myself during my work out, so I can compare it side-by-side to what I did during the session. Great program, and Zach really knows what he is doing!!Posted on Matthew ParkerTrustindex verifies that the original source of the review is Google. I have been having calls with Zach for my shoulder since March, the improvement in my shoulder pain is dramatic. I have gone from daily pain and struggling to get any sort of comfort while trying to sleep, to now having no daily pain and great sleep. I have gone through each of his steps and are now starting on the corrective lifting phase which is amazing progress for me. Like many others for years I struggled with my shoulder and had no real answers from any other physician, apart from exercises that didn't work and aggregated the problem or from a surgeon saying I could have surgery. Luckily I came across Zach's YouTube channel whilst doing my own research, his approach seemed like a perfect fit for me, I put it off for around 6 months but finally signed up and I'm glad I did. The App he offers has been a great help in showing you how to do the exercises correctly and keeping me on track as to what to do. This as well as the zoom calls pushes you in the right direction and can easily point out any mistakes you are making ( I was making allot of mistakes to start with) I look forward to working further with Zach in the future.Posted on Sean GrieveTrustindex verifies that the original source of the review is Google. After over a decade of visiting various physical therapy specialists for a persistent shoulder injury, I had almost given up hope. Multiple imaging studies showed "nothing wrong," yet the pain and dysfunction kept returning despite temporary improvements from other providers. The cycle of brief relief followed by setbacks was incredibly frustrating. From my very first appointment at Corexcell, Zach immediately recognized what others had missed. Not only did he quickly identify the root cause of my issue, but he also provided a clear, realistic timeline for recovery - and he was spot-on with his assessment. What sets Zach apart is his commitment to excellence. While other therapists were satisfied with "good enough" form during rehab exercises, Zach demanded perfection. This attention to detail made all the difference. His meticulous approach is exactly why I believe I'm finally experiencing true, lasting relief for the first time in over 12 years. Beyond his exceptional clinical skills, Zach is genuinely a pleasure to work with. He's knowledgeable, personable, and makes each session enjoyable with great conversation. If you're looking for a physical therapist who will get to the root of your problem and provide long-term solutions rather than temporary fixes, I cannot recommend Zach and Corexcell highly enough. After years of disappointment elsewhere, this is where real healing happens.Posted on Rick PathakTrustindex verifies that the original source of the review is Google. Finally a program that works. Can't say enough good things. Had shoulder issues for years after my car accidents. Many years of rehab through chiropractor, message therapists, various band and strength training didn't do the job. Would get moderate improvements. But I never thought I'd be able to get back on the bench and push the weights I am now. Push ups were just not possible. Lower back pain and stiffness that occurred mainly from walking, GONE! Building muscle in my sixties and losing weight. Wish I had discovered this a few years back. Very grateful for the program you have developed. You clearly know what your doing.Posted on Jeff HeubyTrustindex verifies that the original source of the review is Google. I sought Zach's help because I developed probably a shoulder impingement causing arm pain from doing exercises incorrectly for months and also slipped and fell on ice possibly tearing something. I began watching various physical therapist on YouTube to see how I could improve my shoulder. There was something different about Zach compared to most others. He seemed very confident and enthused about what he was teaching and unlike others he has plenty of client testimonials. When I first contacted Zach I had limited mobility with my right arm. I experience pain when raising my arm above my shoulder or extending my arms straight out in any direction and had to move the arm slowly to control it. I began working with Zack through zoom meetings and following his protocol of exercises. After working with Zack for about 6 months I now have almost as much range of motion as the other arm and quickly with very little pain. At this point I think what pain I experience is at the end of the range and that's probably because I've not been able to get my arm in those positions for several months and the muscles just need to be stretched out. The human body is a very complex designed machine. Zach seems to have a good knack for understanding which muscles need to be strengthened in order to overcome pain, lack of mobility, and improve posture. If you're willing to put in the effort of performing the exercises regularly that he's designed over a time of weeks or months then I highly recommend hiring him.Posted on Evan BTrustindex verifies that the original source of the review is Google. Do you have joint aches and pains? I did before meeting with Zach. Hip bursitis. Patellar tendonitis, a bakers cyst, pulled hamstring, knee pain, turf toe. Many issues. 6 months ago I was unable to get out of bed without knee pain. After working via video call with Zach for a series of months, I can walk/ jog lightly PAIN FREE. He gave and me and can give you hope! I am looking forward to working with Zach for the foreseeable future and cannot thank him enough. 10/10 recommend. Go CoreExcell!Posted on Liam ZahraTrustindex verifies that the original source of the review is Google. I’ve been doing online calls with Zach for the past few months. When i started i was in other words hopeless as i injured my shoulder 5 years ago (19 years old) with no progress over the years of trying every kind of treatment i could afford. Now i’m 24 and after about 4-6 months of working with Zach and I just benched pressed for the first time in half a decade without pain in my shoulder. I could understand where you’re coming from when you think online calls wouldn’t suffice for fixing a serious injury… but this review is proof that the program and zoom calls work. all you need is dedication and patience!Posted on Randal calentineTrustindex verifies that the original source of the review is Google. My name is Randy Calentine I am 63 years old and an avid pickleball player. Within the last year I had to stop playing due to bone-on-bone knee arthritis and rotator cuff problems with both shoulders. 3 months ago, I started working with Zach and the Corex12 Rehab online program and have obtained great results with my knees and shoulders by strengthening the supporting muscles and I am back playing pickleball regularly 3 times a week. My overall fitness has improved as well as my level of play. I am looking forward to continuing the program as I am confident that more gains and improvements are on the way Special thanks to Zach and his Corex12 Rehab ProgramPosted on Gabriella DókaTrustindex verifies that the original source of the review is Google. I am really grateful for Zach's help. I've been suffering from bad knee pain for one and a half years. I had patellofemoral pain and a lot of clicking and popping in the knee. It was a struggle to walk for more than 5 minutes at once. After going to multiple physical therapists with not much improvement I found the CoreXCell YouTube channel and immediately bought the rehab program. After trying for some time I realized the exercises were too difficult to learn on my own, so I purchased the video sessions. Now after only two months of working together my knee feels much better and stronger. I could even start to do squats with weight. All of the sessions happened through video calls and it worked perfectly. I highly recommend Zach and his rehab program to anyone who is suffering from an injury.
FAQ
We have an online scheduler available through the App, which will be provided to you along with directions after your purchase.
Private Therapy Pack-6 Session: Zach will be making changes to your technique and adjusting your program every session. Therefore, to maximize results It is important to stay consistent with Zach following the guidelines below using 6 sessions, over an 8 week period.
- Weeks 1–3: One session per week
- Weeks 4–8: One session every two weeks
Between sessions, you’ll follow your customized rehab program on your own 2 – 4 times per week using the Rehab APP.
CoreX12 Plus – 2 Sessions
It can be challenging to achieve full results with only two private sessions, especially for more complex injuries. The 2-session package can be used in two ways:
- To gain confidence working with Zach and his method, and then upgrade to a 6-session package later.
- For clients who are already confident using the Rehab App on their own and simply want a form critique or technique check.
Scheduling your 2 sessions:
We recommend checking for cancellations and booking your sessions accordingly.
3-Phase Rehab System
Our COREX12 rehab approach is built on a progressive 3-phase system designed to move clients from injury rehab into general fitness & lifting.
PHASE 1 – 12 Foundations
In Phase 1, our comprehensive videos and exercise testing guide allows you to locate and activate the correct target muscle weakness during all 12 exercises — without compensations. If you mostly feel other muscles taking over, the true weakness won’t strengthen, and the injury will not heal.
That’s why mastering technique with lighter weight is crucial in this phase. It helps you build a strong mind–muscle connection to the weak area before progressing to Phase 2. This foundation is the core of the CoreXcell “Feel It to Heal It” Method>>.
PHASE 2: Advancements
Once a client passes all 12 tests in Phase 1, they move into Phase 2. In this phase, the original 12 foundational corrective exercises are replaced with more advanced versions that target the same muscles – but at more challenging angles with greater weight and intensity to fully fix the weaknesses – causing the injury. We also begin introducing basic lifting movements to prepare you for Phase 3.
PHASE 3: Corrective Lifting
In Phase 3, we combine the advanced corrective exercises from Phase 2 with a foundational lifting program. This phase can be scaled up or down depending on your lifting experience and training background.
Once you pass Phase 3, you’ll have the option to progress into one of our advanced programs below:
See Longevity Lifting>>
See Sports Training>>
If you’re consistently hitting the target weakness (with no compensations), you should notice significant pain relief by around 2 months—sleep and daily activities typically feel better with much less irritation.
Note: If you don’t feel relief after 2 months, book privates with Zach — he’ll get you on track.
Long-Term Fix – Back to Training (estimates include the initial 2 months):
- Leg, Hip, Foot injuries: 3–5 months
- Low Back / SI Joint Pain: 3–5 months
- Low Back Herniations: 6–9 months
- Shoulder, Elbow, Wrist Pain: 3–5 months total
- Shoulder Tears: 6–9 months total
- Shoulders: 2x per week
- Legs & Hips: 2x per week
- Volume: 3–4 sets of 15–20 reps per exercise
- Session length: 45–60 minutes
This may not seem like much, but when you’re training the true weakness (not compensations), your body needs adequate recovery to adapt. Doing too much volume too soon often sets you back and increases irritation.
Most traditional programs have clients perform exercises without realizing they’re reinforcing compensations — not the true weak link — so the root cause never gets fixed. Many assume that training a certain plane or range of motion will automatically target the right muscle. That’s where most systems fail.
Our success comes from:
- Precise muscle activation: If you can’t locate and feel the exact weak muscle working, you won’t fix the injury.
- Built-in testing: Every exercise includes testing to confirm you’re activating the true weakness (not compensations).
- Personalized start/end points: Multi-level positions help you start at the right range of motion for your body, so you feel the correct target muscle during all 12 exercises.
