Yes, today is a weights day and instead I did cardio. What is worse is that all I did was a quick sprint mow of the lawn, because it was just starting to rain. Consequently I only did one hour of cardio, at a fairly low heart rate.
Today was supposed to be a leg workout day, however, I couldn't do the cardio yesterday because I didn't have time. I'm going to do the leg workout tomorrow, which should be a cardio day. It's not ideal but that's just the way it is.
