Sometimes as a walking newbie you can experience shin pain, a tight or burning sensation on the front of the lower leg, from overusing weak muscles.
In order to reduce this pain or eliminate it from happening, complete these exercises 4 times through:
- stand on tiptoes; hold for 3 seconds
- roll both feet onto their outside edges; hold for 3 seconds
- lift your toes as high as you can and stand on heels; hold for 3 seconds
- stand normally with flat feet; hold for 3 seconds
