My normal exercise routine is running 3-5 days/week, plus about an hour's cycling, in bits, in traffic, so not really pushing it. Along with the usual walking etc etc.
For complicated reasons, this week, I've had no real cycling, but have been running a lot - in the last 7 days, I've run 6 times, and did a Tae Bo advanced DVD on the day I didn't run.
I am not v energetic though, I'm finding.
Do I need a day off from cardio? From exercise? What?
