Thanks. I do enjoy a bit of elliptical, especially in the colder months - it's definitely a great workout! I'm a bit bummed about running in particular because my tri-sport club has all these great workouts and fun little sprint triathlons coming up, but I don't think I can take it.40mins varied resistance/incline on the elliptical this morning.
Divegirl - if you have access to an elliptical machine, I highly recommend it. My knees are bad too (which is scary because I'm only 25!), but they don't bother me at all on a nice smooth elliptical.
