bodysurfing as cardio?

because of dbol, running has become a real bitch...so i've been trying to find another source of cardio. Well, I'm back in florida now, and will be at the beach at least 3 days a week. Went bodysurfing for about an hour yesterday, and my heart was beating 100 miles an hour. Thinking this would count as great cardio...what do you think?

I would say it a good form of cardio. Stick too that.

you could ride a bike on the beach your calves wont feel like they are gona explode like when running,.......and if your getting a good cardio from the bodysurfing cool...............
