Way back in 2011 when I was discharged from hospital 3 days after spinal fusion surgery, the physiotherapist advised me to buy a set of Activator Walking Poles and start a program of Urban Poling (Nordic Walking) to build stamina and upper body strength. After  5 months of excruciating pain causing inactivity, muscle weakness, joint stiffness and weight gain, I had little energy, my aerobic capacity was limited and my posture poor. The Activator Poles changed that fast.
