STRENGTH & MOBILITY
Jessie brings two approaches together – Functional Range Systems and traditional strength training.
To build strong, resilient bodies, we must first address where our body can and cannot move through the Functional Range Assessment. Then utilizing the Functional Range System we make those areas function better – whether that is through gaining more range of motion, improving tissue quality and capacity, or building strength at end ranges of motion.
Concurrently, traditional strength training methods are performed to build muscle, increase strength, and improve conditioning.
Combining these two approaches means you get to improve your joints and tissues to help you function better while also incorporating traditional exercise for overall improved health.

Functional Range System FAQ
What is the Functional Range System (FRS)?
FRS is a comprehensive, science-backed framework for mobility, joint health, and strength training. It was developed by Dr. Andreo Spina, a musculoskeletal expert, to help people improve joint function, prevent injuries, and develop usable ranges of motion that translate into real-world or sport-specific movement.
FRS includes:
- FRC – Functional Range Conditioning
- FRA – Functional Range Assessment
- FR-ISM – Functional Range Internal Strength Model
- FRR – Functional Range Release
- Kinstretch
What are the key principles of FRS?
Joint-Specific: focuses on improving each joint’s usable, active range of motion – not just passive flexibility
Tissue Adaptation: uses controlled loading to strengthen connective tissue, tendons, and ligaments in new ranges
Progressive & Measurable: it is a system that assesses, trains, and tracks gains over time
Applicable to athletes and general population: Used by pro athletes and everyday people to improve performance, resilience, and injury prevention
What is the FRS Internal Strength Model (ISM)?
The FRS Internal Strength Model focuses on developing strength and resilience specifically within the body’s end ranges of motion and the connective tissues that traditional strength training often overlooks.
What are the key principles of ISM?
Tissue-Specific Loading: trains not just muscles, but tendons, ligaments, joint capsules – areas that traditional lifting doesn’t fully stress.
End-Range Strength: Focuses on strengthening positioning near the limits of your joint range of motion (ROM).
Control & Resilience: Uses isometric and eccentric loading to build control and resilience.
Global Tissue Capacity: Emphasizes tissue adaptation so your body can handle high forces and awkward positions safely – useful for sports, daily life, and longevity.
Should you choose FRS or traditional strength training?
Both! They complement each other. Traditional strength training builds general strength and muscle mass. ISM/FRC fills the gaps by strengthening your joints where they are weakest – at end ranges. ISM/FRC can also open up new ranges of motion, as well as address force/velocity for athletes, and assist in rehab for injuries.
Combining both creates strong, resilient, adaptable bodies.
