I was a little premature in my recovery time assessment following last weekend's hard-core workout. I did not injure myself, nor did I have any cramping or serious pain following that workout. But a full recovery has been slow in coming. I have felt sluggish on my walks all week, but feeling a little more recovered each day. My hamstrings have remained slightly sore and feel like they have doubled in size. I know that they haven't doubled, but as I sit here I feel like I'm sitting on my hamstrings -- not just my legs. I've taken a break from cardio workouts this week. Today I feel good - almost recovered. My legs feel stronger. I'm actually looking forward to my next jog to see if that workout last weekend had any positive effect.
