Now here's a strange one that is for the ladies, only.
Studies have demonstrated that the 2-week period prior to the onset of PMS is one in which fat burning capacity is at a premium.
This is ironic indeed; because that's usually the period in which women don't want to workout; because their body and its emotional computer are preparing for PMS. However, studies in Australia have shown that women were able to burn off as much as 30% more fat in the 2 weeks preceding PMS.
The reason for this, researchers argue, is because this is when the female body's production of estrogen and progesterone are at their highest.
Since these hormones tell the body to use fat as a source of energy, exercising during this time can really pay off. The body will be inclined to target fat cells for catabolism.
