Keep your body moving

• flexion at the waist
• loss of hip extension
• body lean to left at left midstance
• shortened step length
• loss of ankle rocker
• premature heel rise
• decreased arm swing (especially when carrying something in only one hand)

Those signs are typically the result of sitting, not running jumping and overweight!
