you mentioned doing 20 minutes first up, but I train then. when would you prefer the timing for cardio if not first thing in the morning? Does it matter, and do I have to take into account around meal timing, as in a couple hours post meal?
And would you program it, am I trying to go for longer – 20 minutes, 30 minutes, 40 minutes over time. Or can it be getting faster and further in the same amount of time. Like a stationary bike, 20 minutes at level x and distance Y and progress both of those over sessions…is 20 minutes a starting point or is that all we really need….or does progression not matter for cardio as long as a steady state for 20 minutes every day?
