ONERO™ Osteoporosis Exercise Program

Helping adults with osteopenia or osteoporosis rebuild bone strength, improve posture, and move with confidence through the globally recognized, evidence-based ONERO™ program—so you can keep living and playing the active lifestyle you love.

Who is this for?

Spinal X-ray Scan

At Proactive Performance Therapy, we work with adults who want to take control of their bone health—not just manage it. Many of our ONERO™ clients are postmenopausal women who have been diagnosed with osteopenia or osteoporosis and are ready to take a proactive, research-backed approach to strengthening their bones and maintaining their independence.

You might be looking for support if you:

  • Have been diagnosed with osteopenia or osteoporosis and want to improve your bone density safely

  • Want to reduce your risk of fractures and falls without relying solely on medication

  • Have noticed changes in posture, balance, or muscle tone

  • Want to keep enjoying golf, pickleball, tennis, or other recreational activities with confidence

  • Value evidence-based exercise designed to help you move better, feel stronger, and stay active for life

 

If you’ve been told to “just be careful” or “slow down,” but that doesn’t feel right—you’re in the right place.

How can we help?

As a Licensed ONERO™ Provider, Dr. Jonathan Grathwohl, DPT, CSCS, delivers an evidence-based exercise program specifically designed for individuals with osteopenia or osteoporosis. Developed through years of clinical research, the ONERO™ program has been proven to safely and effectively improve bone density, posture, balance, and muscle strength—helping you stay strong, active, and confident.

During one-on-one or small-group sessions, you’ll learn targeted strength and impact exercises that stimulate bone growth and reduce fracture risk—all under expert supervision to ensure proper form and safety.

We’ll focus on:

  • Building Bone Density – High-impact and resistance exercises proven to increase bone mass and reduce fracture risk.

  • Improving Posture & Balance – Functional movements that enhance alignment, coordination, and daily confidence.

  • Increasing Muscle Strength – Progressive training to support healthy aging and long-term independence.

  • Empowering Education – Practical guidance to help you understand your diagnosis, stay consistent, and take control of your bone health.

 

Every session is personalized to your ability level and health history—no cookie-cutter workouts or crowded group classes. You’ll receive evidence-based coaching and individualized support in a safe, encouraging environment designed to help you thrive for years to come.

ONERO™ sessions are offered in person at Par 4 Fitness in Bonita Springs, FL with Dr. Jonathan Grathwohl, a Licensed ONERO™ Provider.
