there are a LOT of misconceptions about nutrition and exercise that are generally accepted by most people.
The biggest for women is that they shouldn't work out with weights because it will make them look bulky and won't burn that many calories compared to cardio.
Both of those things are pure and utter bullshit. Most overweight women (or women in general for that matter) would be far better served by a decent weight training program (in conjuction with some degree of cardio) than they would be by cardio alone.
Weight training strengthens bones and connective tissue, something that's unique to that form of exercise (sprinting is the exception but who sprints?) and is especially important with the high rates of osteperosis.
Not to mention that cardio generally only burns calories *during* exercise vs weight training which burns calories during *and* after when tissue repair kicks in. Also,
every pound of muscle you add requires that your body burn another 20-40 calories a day (according to the most recent estimates I've seen).
So if someone adds 5 lbs of muscle (which is NOT that hard to do with a moderate weight training program and a few months or so), they'll be burning an extra 150
calories a day just to maintain that muscle (meaning you could go to a reduced maintenance routine 2 days a week or something). That might not sound like much but that would mean you'd lose over
FIFTEN POUNDS a year!
Contrast that with cardio where you only burn calories *during* the activity, because (again, unless you're sprinting) you're not really building much muscle (often times it can actually burn muscle depending on your caloric intake).
Finally, weight training also increases functional strength, which is much more helpful in every day life. Think about it, when do you jog or run other than when playing sports or working out? By contrast, how often do you shovel, carry groceries, pick up your kids (or your lover)? Exactly.
PS---Think about this for a second. Which group has a better body generally speaking,
marathon runners or
sprinters? Both are at the extremes, but the answer is obvious...sprinters (who engage in high intensity activity)! It's not even close. Lots of low intensity cardio just doesn't build the kind of body that *most* people find attractive.
Don't get me wrong, if someone wants to do it to build endurance or run a marathon, more power to them, it takes a lot of dedication and persistance! But if they think they're building a body that will have wide appeal, they're wrong IMO, as are the people who think that only jogging/walking every day is the best and only way (obviously some people have joint conditions and can't do high intensity exercise, I get it, and yes it's better than nothing).
