Welcome to Fitness Marble
At Fitness Marble, our mission is to empower older adults to maintain mobility, strength, and confidence through safe, evidence-based physical activity routines. We believe that movement is medicine, and getting older should never mean giving up an active, independent lifestyle.
Meet Arthur Sterling, founder and editor
Fitness Marble is written and edited by Arthur Sterling, a pen name used to protect the founder’s privacy. His background is in quality assurance and project management, not medicine. He turns public guidance from the CDC, WHO and NIH into simple routines for older adults, and every article lists its sources. He is not a doctor or physiotherapist, and nothing here is medical advice.
Our Editorial Standards & Principles
- Safety-First Principles: Every exercise routine includes clear precautions, clear modifications, and warnings against high-risk postures.
- Practical Home Routines: We focus on exercises that require minimal to no equipment—utilizing sturdy chairs, beds, and bodyweight movements.
- Clear Step-by-Step Instructions: every guide explains each move in numbered steps, with an easier and a harder version.
