I'm in my mid-40s and in generally good health (6'3"/220, packing about 5 more pounds than I should). In the last two years, I've noticed increasing joint pain after hard days on the mountain, particularly in my hips and knees. It's not surprising--those joints have taken lots of abuse over the years. But it sucks when I hit day 3 of a hunt and I find myself thinking through every step, especially downhill, because it hurts. What have you done to deal with this? Are there any supplements or exercises that have helped keep your joints in good shape?
