DR. STEFI COHEN

World champion powerlifter.


Doctor of physical therapy.


Strength coach with over a decade of experience in performance and rehabilitation.

Stefi didn’t just study strength. She lived it.

From chasing world records to navigating her own injuries, she saw firsthand how flawed most systems are.

After working with over 150,000 clients, one thing became clear:

People are stuck between rehab and training—with no real solution.

Rehab tells them to rest. Training tells them to push. Neither works.

IOST was built to change that.

This is not outdated theory or fear-based rehab.

It’s a system built on biomechanics, load, tissue capacity, and modern pain science—applied in real-world training.

If you’re ready to stand out as a coach, build real credibility, and stop guessing...

this is where you start.

Trusted by 150,000+ Clients Worldwide

After 16+ years in this industry, I can confidently say this was the best course I’ve ever taken. It opened my eyes to a whole new level of coaching—sharpening my knowledge, leveling up my business, and pushing my personal growth as a coach. Learning directly from Stefi Cohen made it even more impactful. This cohort didn’t just teach—it exposed how much more there is to learn if you truly want to operate at a higher tier. If you’re a coach or athlete who refuses to blend in and actually wants to stand out in this industry, I can’t recommend Stefi’s continuing education programs enough. 🔥

I gained deeper education from a leader in physical therapy along with mentorship from world-renowned athlete Stefi Cohen. This has easily been one of the most valuable learning experiences of my career. From September through January, I spent weekends in live lectures and countless hours during the week studying and being pushed to think deeper. This course wasn’t just about learning new exercises — it was about learning how to truly understand movement, manage load intelligently, and coach strength without fear. What impacted me most was how much the program emphasized the individual. Instead of a one-size-fits-all approach, we learned how to assess how each person moves and build programs around their body, their goals, and what they can handle right now. That shift alone has changed how I design training. It also challenged the common belief that if someone has pain or a past injury, they should avoid real strength training. I learned to see pain less as a stop sign and more as information — something we can respect, adjust for, and work through safely. That perspective has been huge for the people I work with who have movement limitations or previous injuries and want to get stronger without feeling broken. As a Physical Therapy Assistant and personal trainer, this certification truly helped bridge the gap between corrective exercise and performance training for me. I feel more confident guiding people from pain back to strength, and helping them rebuild trust in their bodies along the way. Thank you Stefi!!!

Stefi’s course provided a strong foundation in anatomy-driven programming with a clear emphasis on intentional exercise selection based on target tissue, performance goals, and pain or rehabilitation considerations. The material encouraged critical thinking around strength training rather than rigid templates, which I appreciated as a clinician and coach. The in-person format allowed for open discussion, with frequent opportunities for questions and clarification throughout each session. Stefi was generous with her knowledge and took time to address individual concerns, offer real-world insight, and provide feedback that helped bridge theory into practical application. The interactive nature of the course was one of its strongest assets and made complex topics more digestible and engaging. Overall, the course reinforced key principles of pain-aware strength training and offered a valuable perspective on how to approach programming with nuance, especially when working with clients who fall outside of textbook scenarios.

Last 4 months all of my free time went into this. This incredible course held by the amazing @steficohen . It was a dream come true to be able to receive knowledge from her and i am still pinching myself every now and then to check that it wasn't all a dream. Evidence based solutions, critical thinking, movement assessments, programming, anatomy, mentorship and much more. This was by-far one of the most complex and worthwhile courses that i did, and in my 13 year career i did a lot of them. So the bar is high. Grateful for the opportunity to learn Thank you Stefi. Waiting for the next one.

Anastasia Baranovskaya

Taking Stefi Cohen’s Pain-Free Strength Training course completely changed the way I coach my clients. Stefi’s credentials speak for themselves and she brings an unmatched depth of knowledge about how the body works — from muscles and tendons to movement patterns and pain science. The course gave me the confidence and tools to help clients safely return to training after injury and ultimately get stronger than they were before. I now approach every program with a new framework for improving mobility, reducing pain, and building long-term resilience. Stefi’s teaching style is patient, clear, and incredibly thorough. You can tell she genuinely wants every coach to understand not just what to do, but why it works. I’d recommend this course to any trainer who wants to elevate their skills, stand out from all the ”noise” out there, and make a real impact in their clients’ recovery and performance.

Completing the Strength and Pain Management Certification has been one of the most meaningful professional transitions of my life. Coming from an IT engineering background, your system of thinking about movement, load management, anatomy, and graded exposure clicked immediately with how my brain solves problems. You taught principles, clinical reasoning, and how to think critically. Your ability to blend high-level performance with pain-free strength gave me the confidence to step into coaching with structure instead of guesswork. More importantly, you modeled what it looks like to pursue excellence without losing authenticity. This certification sharpened my skills, elevated my standards, and gave me a framework I trust to help people move from pain and uncertainty to strength and possibility. I am deeply grateful for the rigor, the clarity, and the leadership you bring to this industry.
