Sherry Decker, left and Abby Dill, physical therapist for Lakeland Health, talk about the wellness class for those with low bone density. Bones are living tissue that continue to regenerate.  Osteoporosis can interfere causing more porous bones. A bone scan is one way to check for the condition. Exercise is a critical part of any treatment regimen. Balance is important to prevent falls on fragile bones.  "Bones in Balance" classes are offered on Tuesday and Thursday.
