I Have Hamstrings!

In the soreness aftermath of the tri I discovered that I have hamstrings and that they hurt badly right now! Strength training today didn't really help any either. Why must they always up my weights? Why can't they leave it at the same weight for one session after you reach your goal? I know, because I get stronger if they keep pushing me all the time. They must really hate me because I always say how much I don't like certain machines. After this week I think I maybe only have 2 sessions left. But anyway I did the hamstring machine today which just killed! I'm hoping that it will have helped to get some of the stiffness and soreness out, but it burns in the mean time. Like I said last week, I really understand now that it takes days for muscles to recover from extreme usage. I think my hamstrings were so sore from all 3 events combined in addition to the headwind biking and trail running w/ hills.
