I go to the gym 3 days a week. I work with a PT who helps me with working out on the machines and free weights. For the past 2 weeks, I have been working on my lower body. I have been using the leg press and leg extension. My hamstrings have really been tight, most likely due from sitting and not jogging because of the cold weather we had here in northern Florida. I try to do my stretches everyday, but some days I am just lazy.
