Professional Workshop with Dr. Russell Charno, DC. For Professional Personal Trainers - Not Open the the Public at Large. Gaining a deeper understanding of how your clients move can help you train them more effectively and safely. A few simple screens of mobility, stability and strength can guide you to develop a training strategy that clearly recognizes and accommodates your clients’ areas of weaknesses and movement limitations. We will review movement assessments for the neck, lower back, scapular stabilizer, and the core.
