"Jase (자세) means posture—and also your attitude toward life. We believe physical fitness shapes both. As Joseph Pilates said, 'Physical fitness is the first requisite of happiness.' Jase makes that feel attainable—calm, science-informed, and spine-safe."

Educational content only. Not medical advice. Consult your healthcare provider.
Core Principles
- • Neutral Spine Awareness - Maintain safe spinal alignment throughout movements
- • Graded Exposure - Progressive loading that respects tissue tolerance
- • Breath Mechanics - Diaphragmatic breathing to reduce spinal load
- • Hip Hinge Strategy - Load through hips, protect the spine
- • Glute Activation - Strengthen posterior chain for stability
Breathing
Diaphragmatic breathing reduces spinal compression and activates deep core stabilizers safely.
Neutral Spine
Maintaining natural spinal curves during movement prevents unnecessary stress on vulnerable segments.
Asymmetry Balancing
Addressing side-to-side imbalances common in scoliosis through targeted activation patterns.
What We Avoid

Why I Built Jase
I rebuilt my life after spine pain—and I'm here to help you rebuild yours.
Danced 15+ years. Taught in Shanghai and Korea. Movement was my life.
Diagnosis at 28: Grade-2 spondylolisthesis + lumbar scoliosis. Nothing worked long-term.
Turning point: Found Pilates. Weeks later, pain quieted. Months later, I returned to dance.
Training: Became comprehensively certified. Studied McGill, McKenzie, and more.
Teaching decade: 10+ years helping desk workers move confidently.
Tech background: Google/YouTube taught me to build clear, user-first programs.
"I'm Jenna, a comprehensively certified Pilates instructor and founder of Jase. After being diagnosed with grade-2 spondylolisthesis and lumbar scoliosis, Pilates helped me quiet pain and reclaim movement. I've spent the last decade teaching spine-smart classes and workshops, while my product partnerships background at Google/YouTube taught me to keep things clear and user-friendly. Jase is the platform I wished existed—calm, clear, and genuinely safe."
