I'm still going strong with the Insanity! Finishing up week 4 right now and will be going into the recovery week. One thing that I have noticed tho is that my hamstrings are constantly tight. I do some of my own stretching before firing up the workouts and stretch afterwards as well as at nights, but I just can't seem to get them loose again. While I am still probably more flexible than most people, I know that my hamstrings are tighter than they were before I started Insanity. I'm hoping they will feel back to normal by the end of the recovery week. I might also do the p90x yoga routine tomorrow (my off day) to see if that helps out. Anyone else experiencing this?
