What is ''empty stomach'' cardio?

[Rodja]

Makes sense Rodja! thanks for this information. It's been awhile since I've done circuit training, but I can remember how much I wish I would just die at a certain point through! Definitely gonna start again.

Would it be a good idea to do Circuit training upon awakening? Since I can just drive to the gym. A good balance would be 2x per week Circuit Training on empty stomach and 2x per week sprinting intervals? or just replace sprinting with Circuit training completely?

And also what should I use as regards supplements? since that was something I was wondering about as well. The extra Virgin Olive oil is a good add or no?

I'm not a huge fan of it on an empty stomach, but it can be done. There is some solid research regarding ingesting a fat source to increase fat mobilization.
