Heart

Strictly in terms of "heart health" benefits, is there a big difference between cardio sessions of 20-30 mins, 45 mins and 1 hour?

Minimum 30 minutes. Long isn’t necessarily better. What may happen is that your body switches from aerobic to anaerobic, which is a different conditioning factor.

   I think the longer the better, but a minimum of 30 minutes.
