Hey! I'm studying abroad in Russia next summer (so excited!) and I'm not concerned about weight training as I can do that without a gym; but I'm concerned about cardio. There's no internet in the dorms at Moscow State University and the gyms are difficult to access. I also have achilles tendonitis that flares up in cold weather, which will make it difficult to run in Moscow. (even during the summer, I'm told) Here I like to cycle, but I probably won't have that option in Russia.
I'm pretty athletic so I'm often frustrated about how darn easy most low-impact workouts are. So can anybody suggest some low-impact, HIGH-INTENSITY cardio workout DVDs for me?
