Main Elements of FRC
Functional Range Conditioning (FRC) revolves around three key components aimed at improving mobility and joint function by focusing on movement control and the resilience of the musculoskeletal system.
Controlled Articular Rotations (CARs)
At the heart of FRC training lies Controlled Articular Rotations (CARs). These exercises guide joints through their full range of motion while actively engaging the surrounding muscles. The emphasis is on isolating one joint at a time, ensuring the rest of your body remains stable. For instance, during shoulder CARs, you create large, deliberate circles with your arm while maintaining tension throughout the movement.
"CARs are active, rotational movements at the outer limits of articular motion." - Functional Range Conditioning
To get the most out of CARs, aim for 3–10 repetitions per joint daily at about 50% effort. This practice not only highlights restrictions but also helps build joint resilience.
PAILs and RAILs Techniques
Progressive Angular Isometric Loading (PAILs) and Regressive Angular Isometric Loading (RAILs) are advanced methods designed to increase mobility and improve joint function through targeted muscle contractions.
- PAILs: Focus on contracting the muscle being stretched while holding an end-range position.
- RAILs: Activate the opposing muscle to deepen the stretch.
"These techniques, PAILs and RAILs, are not just about stretching. They are designed to create significant and lasting improvements in joint function. They retrain the nervous system, restructure the tissues, and build active control in newly acquired ranges of motion. In essence, PAILs and RAILs are the key to not just moving better, but staying better. They are the secret to unlocking your body's full potential and achieving better mobility and joint health." - Brian Murray, FRA, FRSC
These techniques work hand-in-hand with muscle tension strategies to refine joint control and stability.
Muscle Tension Methods
FRC incorporates active tension techniques to engage muscle spindles and Golgi tendons, helping to expand usable ranges of motion. This "teaching tension" approach involves actively generating force to push through movement barriers. By improving communication between the brain and muscles, this method enhances joint control and function.
"Mobility, in an FRC sense, is defined as strength and control in order to expand upon usable ranges of motion, articular resilience, and overall joint health." - [P]rehab
Rather than relying on passive stretching, FRC prioritizes active muscle engagement. This approach builds strength and stability at the end ranges of motion, ensuring that any improvements in mobility are functional and long-lasting.

How FRC Changes Your Joints
Functional Range Conditioning (FRC) brings about both structural and neural changes that enhance how your joints function. Through consistent practice, your body adapts in ways that improve joint strength, mobility, and resilience.
Your connective tissues - like fascia, bone, ligaments, joint capsules, and tendons - are packed with nerves, accounting for about 80% of the nerves in your joint structures. Over time, FRC strengthens these tissues, making them better equipped to handle the stresses and movements you encounter daily.
FRC also works on your brain. By stimulating the central nervous system, it helps rewire movement patterns, building a foundation for cellular changes that further support joint durability.
A key part of FRC’s effectiveness lies in its ability to trigger fibroblast activity. Mitch Broser, DC, a Functional Range Systems Instructor, explains:
"Cells called fibroblasts are responsible for the rebuilding and reorganizing of connective tissues... These fibroblasts need to be told how to repair an injury. We can 'talk' to them through movement."
These adaptations collectively improve your joints in three main ways:
- Tissue Strengthening: Gradual loading helps build connective tissues that can withstand greater forces.
- Neural Control: Enhanced neural coordination leads to more precise, controlled movements.
- Joint Capsule Expansion: Training expands the joint capsule and strengthens it in its full range of motion.
Dylan Elgas, an FRC mobility specialist, highlights the benefits:
"Ultimately, doing all these different training system protocols is going to lead to us carving out more of a joint capsule, layering in quality connective tissue, and then increasing muscular control, endurance, and strength in those positions."
Unlike the fleeting benefits of traditional stretching, FRC delivers lasting improvements to tissue quality and neural control. This comprehensive approach not only boosts joint health and mobility but may also slow down joint degeneration over time.

FRC for Beginners
Getting started with Functional Range Conditioning (FRC) is straightforward: consistent practice helps improve joint mobility and build strength.
Daily CARs Practice
Controlled Articular Rotations (CARs) are the foundation of FRC. Think of them as "brushing your teeth – but for your joints". A daily CARs routine takes just 10–15 minutes and is most effective when done first thing in the morning.
Here’s how to get started:
- Perform 3–5 rotations for each major joint.
- Keep effort light (around 0–30%) during morning sessions.
- Make large, controlled circles while keeping the rest of your body stable.
- Use a mirror to monitor your form and ensure proper alignment.
Basic PAILs and RAILs
Start with a comfortable stretch, such as a seated hip stretch, and hold it for two minutes while breathing normally. After that, gently contract the muscles being stretched at about 20–30% effort for 30 seconds (PAILs), followed by contracting the opposing muscles for 10–30 seconds (RAILs). Maintain steady breathing throughout the process.
These techniques lay the groundwork for more advanced FRC exercises.
Progressing to Advanced Levels
Once you’ve built a solid foundation with daily CARs and basic isometric techniques, you can gradually work toward more challenging practices. Progressing safely involves increasing tension and complexity in small, manageable steps. For instance, one individual significantly improved their shoulder and neck mobility within three months following a car accident.
To advance effectively:
- Master the fundamentals before introducing more complexity.
- Gradually increase tension during your CARs practice.
- Work with a qualified FRC practitioner to ensure safe progression.
- Prioritize quality over quantity in every movement.
- Pay attention to your body’s signals and adjust intensity as needed.
