Thanks for the tips.... I worked out yesterday for 2 hours, doing a lot of high rep squats, leg curls, and then did some upper body with bench press, pull ups, dips, and some free weight curls, and ran on the tread mill for 20 minutes. I feel a lot better after I work out... I am sore but that lets me know that I did something. I think that cross training your body will help a lot on the trails. Get more stamina and strength for climbing.
