Anyone out there ever do sprints for cardio? I'm thinking about trying it a few times next week while I'm on vacation since I don't have room for a step (I do however have KPC, KM & MIC at the beach house
).
So those of you who've tried sprints, how do you do it? Like, 3 minute sprints/2 minute fast walks? For how long? Is 30 minutes enough or do I need to go for the dreaded 40-45?
