A flat trail is rare. To truly protect your joints, you need to adjust your pole length as the terrain changes:
- Uphill Climbs: Shorten your poles by 5-10 cm. This gives you better leverage to push off and prevents shoulder fatigue from reaching too high.
- Downhill Descents: Lengthen your poles by 5-10 cm. This allows you to plant the poles securely ahead of you, absorbing the heavy impact that would otherwise hit your knees.
