Seriously, I'm in such good shape (cardiovascularly speaking) that I can do 75 rpms for about three miles and not break 120 beats per minute. I only start to creep into 130/135 when I am heading up a steep grade or sprinting or heading into a stiff wind.
For my weight and age, 135 is my target rate anyway. It changes as you get older. *is old* My resting rate is 65 which is very good, but if I go too high (anything over 145) when I work out, I take too long to recover. There's not enough oxygen being moved around by my blood because of the anemia...that's the reason my doc gave me. He wants all my workouts to be "moderate" until we get those iron levels up.
It's funny how I was compensating for this, even before I knew about the anemia. I always know when to back off. My rule of thumb is I want to be sweating lightly and just breathing deeply but not gasping, with my heart rate up but not pounding. That's an aerobic exercise, for me.
