Day 22: Cardio

The plan this morning was to do Cardio X and 45mins on the stationary bike.  Unfortunately I felt some tightness in my left calf(the same calf that was bothering me last week), so I did 20 miles on the bike which took me 75mins.  According to the bike I burned 625 calories.  It's not Cardio X but it's something.  I may have to use the bike as my Cardio for another week until my calf is completely healed.
