Today was a day of rest, which is good as yesterday toward the middle of the workout I started to develop a shin splint in my left leg. I walked to the local coffee shop this afternoon, which isn't too far, and on the way back it started to re-surface.
Various medical websites tell me I'm probably not going to die, so that's good. The most common cause of shin splints is a sudden increase or intensity in physical fitness.
I'll try to continue tomorrow at a significantly lower rate and see what happens. I really hope this doesn't delay me too much.
The weird thing is, with the Insanity program I'm actually looking forward to the workouts, which is a first for me. On Day 2 I was really looking forward to this day off. Today, though...I kinda miss it.
