Muscle Building

A 2018 study by Nagoya University found that muscle quality was improved among 31 participants after 10 weeks of regular 30-minute sets of walking. 

Walking is predominantly going to be working your lower body, and mainly stimulating your quadriceps, hamstrings, glutes, calves and hip adductors, as well as your spine and abdominal muscles, which all have a significant role in stabilizing your trunk as you move forwards.
