Hello and welcome to Zoey Shorts, the bike size podcast where we discuss one topic around

science and nutrition. I'm Jonathan Wolf and today I'm joined by Professor

what it means can you explain it? Yeah so I think we should perhaps firstly address what isn't

considered cardio and that would be things like strength type activities things like weight lifting

and these activities are sometimes called anaerobic activities and that word means your body is
