Hiking isn’t just good for the soul - it’s one of the best forms of exercise for longevity. Long, steady hikes typically put you in Zone 2 cardio, that sweet spot where your heart rate is elevated but you can still hold a conversation. If your knees hurt, you’re far less likely to get out on the trails and enjoy those benefits. For many adults in their 40s, 50s, and beyond, it’s knee pain - not lack of motivation - that sidelines them.
