I'm done for the week. My PT and coach pled with me to hang it up for the week as I have strained my calf muscle. I guess i risk more by pushing it than by hanging it up for a few days and hitting it again on Monday. It pains me to back off but it's important. I will try and do some biking the rest of the week to keep me from going crazy.
Just "ran" 4 miles on the elliptical. That definitely works a different set of muscles. According to the machine I did the 4 miles in 35 minutes. Man, I thought a treadmill was boring.
