I know these have been discussed a lot. However, I just started doing them again this morning. I use a hill in the woods on my old high school campus. Its about 100m long with 2 major inclines, the steepest being at the very top. You really need to dig deep to finish strong. After warming up I sprinted it 4 times, only resting while I walked back to the bottom. I only did 4 because I'm in the squat contest and am going for a pr tomorrow, so I didn't want to tear myself up too much. My goal is to do these at least once a week for the rest of summer. Maybe ill even wear my weight vest at some point. I just felt like starting this thread to motivate myself (and hopefully some of you) to do these painful exercises.
