There are more than 10 muscles working at the same time when walking, and the heart is one of them. Regular hiking develops, forms and tones muscles of the legs, hips and buttocks. Walking enhances the strength and endurance of these muscles, making it one of the best workouts.
In addition to the heart, walking affects the following main muscle groups: calf muscles, tibialis anterior and ankle extensor muscles, hamstring muscles, quadriceps muscles, hip flexor muscles, buttock muscles, arm and shoulder muscles, and abdominal muscles. It is vital to stretch the muscles before and after walking to sustain flexibility and prevent injury.
