Today exercise was hard. I didn't sleep well last night and I am sooooo tired!!! Still I managed to eat well and get in 35 minutes on the treadmill. I wish my endurance would start to improve. I managed 5 minutes on speed 3 but I get burns in my right calf even when I walk regular outside. It gets like it is locked and hurts badly. The other leg never hurts. hmmmm.
