proper heart rate

[lbclash]

I am 1 month shy of 60 years old. I do cardio and have done so most of my life. I am trying to find my correct heart rate. When I use the 220 minus your age formula I do not get the feeling I am getting enough workout. Any idea out there on how to find my proper cardio balance?

That 220-age formula isn't very useful. Here's an earlier discussion of it:

Max Heart Rate = 220 - age?

There's some other formulas to calculate max and target. I always got pretty much the same result as the cardio machines

Taking resting heart rate right after waking can be kind of fun if you haven't done before. First time I did it, I thought I was clinically dead.

At 60 isn't any heart rate the proper one?
