There are many totally different opinions on this subject. For some, it’s a common a part of their coaching, whereas for others, understanding on any empty abdomen is out of the query. In immediately’s weblog put up, we’re going to have a look at the three largest myths and present you the reality behind them.

Within the case of a high-intensity working session, like interval coaching, the share of power produced by burning fats is considerably decrease.
