From Head to Toe: The Ultimate Stretching Guide

If the previous stretch isn't deep enough for you, then try this variation. It's perfect for doing on a bench after a run in the park.

• Prop your left heel up on a surface that is a little lower than your hip, such as a chair or bench. Flex your foot.
• To increase the stretch, bend forward toward your flexed foot by creasing at your hips. Hold for 30 seconds and switch legs.
