Tracking Methods
&Â Tools
Tracking your progress is one of the most powerful tools for boosting your flexibility gains. Our programs provide detailed guidance on tracking progress from session to session and within each session, using both traditional and innovative measuring tools.
High-Quality
Video Tutorials
Professionally produced video tutorials covering every aspect of your flexibility training. From foundational theory and technique breakdowns to specific warm-ups, progressions, and recovery protocols - you'll have crystal-clear demonstrations for every phase of your journey.
Also Included
Side SplitÂ
Flexibility Mapâ˘
A unique tracking system developed exclusively by our team.
This innovative tool lets you visualize your exact flexibility levels across all components of the Side Split, track improvements accurately, identify strengths and weaknesses instantly, and monitor your progress with precision.
 Pelvic Tilt
Specialty Program
Being able to tilt your hips is an essential ability for building flexibility, yet it's rarely trained directly.
To improve our studentsâ results, we created a dedicated program that helps them properly develop their capacity to tilt. It's included as a bonus in every ROS⢠Program.
Side Split
Maintenance Programs
Achieving flexibility is just the beginning - keeping it for life is what matters.
Inside every ROSâ˘Â Program, you'll find dedicated maintenance protocols for each skill, guiding you from the moment you first achieve your goals all the way to lifelong retention.

The maintenance programs guide you from the moment you first touch down all the way to long-term maintenance.Â
We achieved the side split as adults
Our flexibility journey began as stiff adults with limited time for training
(we were also obsessed with strength training back then). Given our starting point, the margin for error was small, especially when aiming for challenging positions like the Side Split.
Looking back, itâs clear we didnât train harder than others; our success came entirely from our methodology (ROSâ˘).

Why do most Side Split programs fail?
 The problem:  ordinary people attempting fundamentally flawed programs, then blaming themselves for failing.
What makes these programs flawed?
- Ignore the mechanisms that dictate flexibility in human physiology
- Use only a very small part of the proven available methodology
- Ignore the science on optimal training variables (reps, sets, duration, intensity) and just do what 'worked for them.'
- Vague and uninspiring structure with no measuring tools, tracking systems, professional guidance, support, or accountability
The only people who can benefit from such programs are the naturally flexible. Those are what we call in science 'fast responders,' and they can get results from pretty much anything (even a weekly yoga class).Â
For the vast majority who aren't naturally flexible, it's impossible to make meaningful progress with such programs, as they strip away the most critical factors that unlock your true potential.
So stop blaming your age, genetics, or training level.

You just need the right approach.
Why do most Side Split programs fail?
 The problem:  ordinary people attempting fundamentally flawed programs, then blaming themselves for failing.
What makes these programs flawed?
- Ignore the 4 proven flexibility mechanisms
- Use only a fraction of the available methods
- Ignore training science (reps, sets, intensity)
- No tracking, guidance, or support
For the vast majority, it's impossible to make meaningful progress with such programs, as they strip away the most critical factors that drive progress.
So stop blaming your age, genetics, or training level. You just need the right approach.
What makes our approach
different?Â
Grounded in Exercise Physiology
Research today shows how our physiology responds to different training stimuli. The key findings: which mechanisms increase flexibility, which methods activate them, and how to apply them effectively (reps, sets, etc.).
The ROS⢠Programs put it all together in a simple framework, delivering the right practices at the right time for your level.
Innovation
The ROS⢠Programs exclusively offer the original methods developed by our team (C-PR and A-AR), innovative end-range contraction techniques, and proprietary tracking tools like the Flexibility Mapâ˘.
Some tools extend research-based techniques, bridging active- and passive-centered methods, while others address areas where existing theory has not yet provided proper implementation strategies.
Individual Assessment & Customization
Complete our step-by-step guided ROS⢠Assessment to evaluate your current flexibility, gain insights into your unique needs, and customize your plan accordingly. Discover your strengths, weaknesses, and imbalances with precision.Â
Not just a program...
Thereâs a reason our students see incredible value in joining us. We donât just invite you into a programâwe invite you into the largest flexibility knowledge base that exists.Â
Each program includes numerous video tutorials covering every aspect of your training, PDFs with program guides and reference materials, and additional resources for ongoing support.
