As people progress in age past their 20's, and in some cases in their late 20's, they begin to lose a percentage of muscle mass every year. This percentage increases with age. Now here's the kicker: Strength training combats this genetic decline... cardio accelerates it. You see, in order to continue to increase muscle mass as you age, you must create lean, fast twitch muscle fibers. Cardio tends to atrophy (eliminate) fast twitch muscle fibers in favor of less toned, weaker slow twitch fibers. What's that you say? You don't care about your muscle composition because all you want in life is to be skinny? Well, cardio dosen't help that either!

Women who lift trim down instead of bulking up!

Lean, fast twitch muscle fibers require more calories to function then their slow twitch counterparts. So when you run or bike for miles and burn all those calories in the short term, you are actually making it harder for your body to burn calories in the long run. If, instead of running for an hour you chose to lift weights, you would create lean muscle in your body, and as a result every activity you do would require more calories. In other words, lean muscle will increase your basal metabolic rate! This lean muscle also appears to be more firm and more aesthetically pleasing. And you will be able to maintain this appearance into your old age. You simply cannot get this benefit from cardio. 

Most of us find ourselves in this
position for extended periods of time
every day, which is horrible for our
posture! 

Now let's talk about posture, which also tends to degenerate with age. Most of our lives today are anterior centric, or "forward leaning." From driving your car, to sitting at your computer, you spend a large part of your day hunched over with your shoulders rolled forward and your head sticking out forward like a chicken pecking for food. When you bike or run, you force your body to do the same thing only under a greater amount of stress! Just look at the next runner you see in your neighborhood if you want proof. This is horrible for your structural integrity, and for your overall appearance. Strength training, however, can correct this. I'll do a post soon about all the life benefits of good posture, but for now, just take my word for it... good posture is critical for long-term quality of life.

Next topic... let's address the concern that most women bring up to me... 

A lot of females believe that if they strength train they will bulk up like Arnold Schwarzenegger. This is simply impossible. Men have a much higher ability to gain mass and muscle due to their testosterone levels being far higher than those of women. Those "freak" female body builders are almost all on steroids. Women will actually appear thinner, and more trimmed down when they follow a lifting program. If you think you're different, you're not! Lifting weight burns both the fat surrounding your muscles and the fat within your muscles (and yes, there is fat within your muscles in the same way that there is fat in the middle of a nice juicy steak). This results in a trimmed down, toned appearance. Without the use of supplements like steroids and testosterone boosters, women cannot physically bulk up to "disgusting proportions". As long as females follow a healthy, calorie-conscious diet in conjunction with a proper lifting program, they will trim down, tone up and look sexier than they could ever look by doing mass amounts of cardio.

Biking, a form of cardio, is ineffective.

So cut the crap cardio and start getting more bang for your buck... lift weights!
