I'm scheduling in some cardio work (cardiac output) three times a week over the next month or so to see if I can extend the amount of training I can do in a given session. Today was the first day on the treadmill for cardiac output work in a long while, so I took it relatively easy with a three-mile trek at modest mph's.
The goal is to keep myself in an aerobic state for a full 50-55 minutes. Tuesday's session went well on that score. But "first days" can be deceiving. The real trick will be to see how I'm faring come Sunday.
