From Head to Toe: The Ultimate Stretching Guide

This is one of the easiest stretches to do as soon as you finish a run. If you have weak Achilles tendons, do the variation using a wall instead of a ledge.

• Find a wall and stand a few inches away. With one foot, put your toes on the wall, keeping your heel on the floor, and flex.
• Hold for about 10 to 15 seconds, then alternate with your other foot.
• You can also do this stretch using a curb or step and hanging your heels off the ledge.
