Middle age is not too late to increase cardiac fitness

Agree that outside is best, but it depends where you live. I roll my spinning bike out on the lawn in summer at the lake. Is 10-15 miles a week enough cardio for you? I would usually get about 240-300 minutes of quite intense cardio every week.

I hike/walk and bike in addition to running. 5-10 hours a week. Not very intense though.

I just started the reduced running plan a month ago. Hopefully 10-15 miles per week intense running combined with low intensity walking/hiking/biking will be enough cardio.

I run on a treadmill in front of a tv. The flexing of the machine reduces impact of running.
