> even jogging in place got me over 130

The cardiac exercise research group in Norway have developed and tested an online maximum heart rate calculator.

Check what that number is for you.

The interval training they recommend would be about 90% of maximum heart rate.

(For example, I'm in my early 60s and I'm supposed to push my heart rate into the range 150—165 bpm.)

Interval training is different, it's supposed to spike your heart rate for short(er) periods, so that makes sense. When people are talking about running easy or being able to have a conversation, they usually are talking about low to moderate intensity aerobic zone or "zone 2", which goes to 75-80% HRmax depending on who you're asking. Some would even explicitly recommend 120-130 bpm range.

Depends on our age and size and conditioning.

So "jogging in place got me over 130" may be just fine, or may not be.
