Thank you for this interview Gordon. Do you have any final words?
With cardio, just like everything else you do in the gym - or in life for that matter - resist the urge to blindly follow advice. Don't be afraid to be skeptical, and don't hesitate to pose the ultimate question, which is of course "why."
If someone recommends an exercise, a style of training, or a way of eating, ask that person to explain the logic behind the suggestion. You might find a lot of people who are willing to give advice. Before you follow any, make sure these people have good reasons to back it up.
