Core training is a concept that is often misunderstood. You regularly hear people discussing 'the best ways to get a 6-pack', or giving advice like 'make sure you use a Swiss ball' or 'add weight to your sit-ups.' Invariably this sort of training is labelled core stability training, but I would argue that the stability element is often forgotten.
Mindlessly staring at a question for minutes on end doesn't make the answer magically appear. All it achieves (if achieves isn't too strong a word in this context) is to make the question seem even more incomprehensible than it did in the first place. And it seemed pretty incomprehensible initially.
The underlying problem is that for women over 40, exercise ALONE is not enough to cause weight loss. This is not true for men. And it's less true for women under 40. But if you ask most women over 40, they will tell similar stories of exercise programmes that no longer delivered the goods when it came to weight loss.
I have written before that stress will eventually lead to people, who are normally vigilant with their diet, going 'tonto' - and losing control. Check: there is a wonderful photo of me gazing amorously at a slice of pizza like it is Monica Belluci. I didn't meet a single carb that I didn't like in Spain. Once I started eating badly, I didn't stop.
Alcohol is ubiquitous at this time of year. Abstinence may make you feel virtuous but can also be dull. If you do drink, I'd advocate men avoiding beer. Beer increases levels of an enzyme called aromatase. This converts testosterone into oestrogen and leads to fat deposition around the pectoral - the dreaded man boobs. Stick to a few glasses of good quality red wine instead.
