Women should lift weights!
For two reasons.
1 - most women (but I appreciate not all) would like to lose a little weight. Endless hours on cardio machines is never going to help you do this. Lifting weights, combined with nourishing food, will. And it will leaving you looking fit and strong rather than just skinny.
If you want to put on weight - muscle's better than fat!
A great deal of the food you eat is turned into glucose and stored as glycogen is in your muscles and liver; the more muscle mass you have, the more scope your body has for storing that glycogen - the less gets turned to fat!
(By the way, those of you saying you can't lift weight becasue they bulk you up are misinformed. If you genuinely have the secret to how you can bulk up so easily, you are sitting on a fortune; men have been after the secret of bulking up without steroids for years, it just isn't going to happen.)
All women should be able to feel powerful, in control and like they could do anything!
It should be the law.
