Firstly, how am I to know whether I am jogging too much over a week? I currently jog for 30 minutes every other morning before breakfast, and I think that's about 3 miles. I feel absolutley fine after the jog and throughout the day, and I'm 16 years old. But I've heard some people say that certain amounts are too much, so is this okay?
After reading about HIIT and interval training I've decided to give it a try instead of jogging, but I was wondering how much variation I should add into the workout. Is variation simply there to stop things becoming boring and tedious, or are there any fitness related reasons for mixing it up? Should it be mixed alternatley (eg. bike, jog, bike, jog), or periodically (eg. 1 month bike, 1 month jog)?
Is HIIT still a good idea for the mornings before breakfast? Common sense tells me that there's more risk of making yourself ill or black out with no food inside you, especially when the intensity is increased.
Judging by what people have said regarding HIIT, am I right in thinking that statements such as "high intensity cardio builds muscle, low intensity burns fat", "low intensity cardio for long periods is better than high intensity for short periods".....are false?
